I was driving on some back roads and floored it in second, well the rpms shot up to 6k right after shifting in second felt like the trans completely slipped a gear. then it got stuck in third, I had to slow down and it is now stuck in second. I get to a light and stop well now i'm stuck in first. Right now thinking crap i need to find a way home. so i drive it like that finally it shifts to second for a while and i'm able to slowly make it back running lights and such (it was late no traffic). then i get back and grab my code reader well when i plug it in the stupid cel turns off! dammit. so i go drive it around again, the idle is surging all over and acceleration is messed up sometimes will go, other times really slow. it feels messed up but the cel doesn't come back so i go home. its shifting normally now but something doesn't feel right. Now sure what to do...

almost sounds like your tranny is on its way out ...

a lot of people's auto trannies have been going out lately ... A LOT.

Dam that sux!! So is the check engine light on?? Seriously I think this car is really not worth it no more. Just get a used tranny at a junkyard and sell this car......

 
Rep Power: 363

or swap ... hehehehe.

 
Rep Power: 812

as soon as it revved the light came on but now its off and shifting fine, just not driving fine. im so pissed cause the car was feeling awesome the last few days everything good with the new intake. i thought at first its the tb but i've been using it for months with no problem and the cables are all a bit loose too so its not that.. nobody will buy my car its been in a big accident and more. i wonder if warranty will cover whatever is wrong. i got too much into this car to just give up.

 
Rep Power: 363

perhaps you blew a fuse or a sensor got disconnected?

 
Rep Power: 346

Oh yea, forgot about that accident you had. Yea it sux to just give up your car like that but if it just keeps on givin you problems i dunno. I must sell my car before my tranny warranty is over cuz i know for sure and i have a really good feeling that the rebuilt tranny isnt gonna last........

 
Rep Power: 812

ya this is retarded for honda to make such a POS and not do anything. I baby this car so much for the past 4 years it had 10k fluid changes, even a trans cooler. I've maybe floored the car 10x since i've owned it. I thought it would last over 10 years but so much for that one. when i was driving home it felt like the throttle cable snapped almost but the car was still moving and rpms were up. when i parked it was idleing at 1500rpms.

 
Rep Power: 363

yeah... you already know that 7g auto trannies are notoriously bad.

I suggest getting a manual trans swap ... or even better and only a little more expensive is a K20A3.

just thought of something too ... it also does sound like a very bad vacuum leak. Check all connections and hoses especially around the intake mani and throttle body!

 
Rep Power: 346

Haha, I went to a used car dealership and they only want $7k for my car

 
Rep Power: 812

i don't know how a vacuum leak would happen but i'll check. i installed the intake and everything was fine, then out of nowhere it happens. tonight when i was driving it actually still felt normal til i floored it and ruined everything.

if the car is shifting fine when the light goes out, you more then likely have an electrical problem somewhere. possibly a bad connection on a part or a intermittent failing component. or possibly a vacuum leak. make sure everything in the engine bay is hooked up and installed properly. other then that I would drive around with the code reader plugged in and as soon as the car starts acting up and the cel comes on, quicky try to see what code it is.

let us know if you do find out the code.

Dont start replacing anything untill you find out why the light keeps coming on. and dont assume the tranny is messed up. You know as well as I do that a small electrical problem or simple mechanical problem can cause the tranny to function iratically. As well as the vehicle.

This happened to me very recently, getting off the freeway I only had second and then it moved down to only having first, then my transmission when completly out, sucks

 
Rep Power: 0

My cel came on too but then went off but my car kept losing gears and the light never came back on by the way

 
Rep Power: 812

well if its the tranny i need to drive it more so it goes out. i'm not letting this slip by warranty. i'm gonna take it out again after work tonight. streetglower, electrical failure seems very odd for something to just break for no reason unless i got struck by lightning or something. what i don't understand is how turning the car off and then back on completely changed the problem from trans not shifting to idle surging. the cel was throwing at least a few codes they kept popping up faster than i could read and then disappeared in a few seconds. i'll try it again.

 
Rep Power: 453

electrical failures happen all the time. Most every part on a car today is controlled electronically. Most parts are electronic. if the ECU is throwing several codes, I am 99% positive that the problems you are having is related to why those codes keep flashing. Remember the thread I made awhile ago, anytime the car starts having problems and the check engine light comes on, it is usually related to that. Now if you had all these problems and there was no check engine light, then you would have to do some diagnosing to see exactly what was happening. But since you have codes that are flashing, once they are retrieved, you can diagnosis based on those codes. If the trans isnt shifting right, you may have some codes related to the tranny or possibly from the TPS. you may have a failed sensor or may have a failed solenoid in the tranny or other problem.

But if it is under warranty, I would take it in and have them fix it for free.

 
Rep Power: 812

yup you're right. 0123 TPS sensor voltage high. The stock TB is going back on today. I swear you can't do ANYTHING to these cars without screwing it up. looks like its back to just intake and exhaust at least they can't cause any problem theyre just a bunch of pipes..

 
Rep Power: 314

why dont you put your coad reader in the glove box???

 
Rep Power: 363

that's very odd how a tps problem would cause your tranny is act weird???

well ... I'll tell you first hand that k20's are mod friendly ;PPP

 
Rep Power: 812

well tps tells the tranny how hard you're pressing the gas which then determines how it shifts. when i floored it in second it got confused and downshifted back to first or something. we'll see what happens i'm relearning the idle with new tb.

 
Rep Power: 302

Gear... did you doublecheck all those ground connections from the engine harness? Flaky grounds wreak absolute havok with this car. Especially when YOU touch it Just kidding.... but if you touched the intake, double check those wires again just to rule that out.

 
Rep Power: 812

okay it seems to be fixed now and alot slower but at least the intake and exhaust are doing fine. i don't think i'm getting any more mods after this. its not worth paying and then paying again to put it back to stock and realize you're going in circles. but everything works now no cel after flooring and smooth idle. thanks everyone.

 
Rep Power: 812

i actually had those off the day before making sure there wasn't too much rust. they all look fine. haha yea no more touching or modding. i have a few things like plugs and voltage stabilizer but they don't really count. also i noticed on the old ported tb the tps was way off center. i know it had to be cause the plate is bigger but maybe it sprung a leak or something. lousy civic. i bought it thinking they were made to be modded. boy was i wrong.

 
Rep Power: 0

good thinking, im just going to stick to exterior and keep up with my fluid changes, btw i forget how do you do the idle relearn thing

 
Rep Power: 0

gearbox, it might be lousy, but u know u love your civic lol

 
Rep Power: 812

its working fine now but man it feels alot slower! i wish the dumb car would take the mods. but yea i'm done with exterior and now engine too. i'll just maintain it and see what happens. no way am i getting a turbo like i planned the car can't even work by itself.

idle learn is just driving car around til warm, turn off, pull out FI ECU fuse or battery, put back, start car, idle 10 mins without touching gas or accessoires, turn off, turn on, drive.

 
Rep Power: 453

well at least you didnt have to waist your time taking it into the dealer.

 
Rep Power: 812

ya especially considering the dealer is over an hour away

 
Rep Power: 0

can you not adjust the tps on the 7th gens? if not that sucks. if you can like every other honda, you should be able to set to the stock setting and work with your idle screw and throttle stop to find something that'll work for you.

 
Rep Power: 812

ya ideally. the tps is held with some weird screw/rivets that can't be taken off. otherwise i would've played with it and set the proper voltage. the problem with the bore is the idle adjust screw doesn't work anymore. the lever just sits against the tb. so it wouldn't have helped trying.
