Today, I drove for a while and when I was parked to see the map, the car was shaking, so I was what the hell and looked at the RPM guage, and it was dropping to zero and back up, drpiing to zero and back up.
I thought it was nothing but random thing that happens. so I put my car in reverse, but while reversing, car shook and died. never happened before, so I turn my car on again, put it in Drive, and drove. but it wouldnt go over 3000rpm and doesnt want to go from first gear into second or third gear.
damn it.
also, sometimes when I am on Park, RPM bounces around sounding/shaking like it's gonna die soon
What could be wrong?
engine oil, tranny fluid seems alrite. checked to see intake filter but looks clean.
I had resgenator taken out for 2 days from stock intake and put it back on but still having problem

not sure about civics, but maybe one of your vacum hoses poped off, check your spark plugs too maybe? althought they wouldn't fail just like that.

Reset the ecu, make sure there's no engine light. Otherwise it may be a sensor or you could try raising the idle rpm.

ITS your MAF sensor dude ......or MAP whatever they call it

REP please

yeah.. but what about the map sensor? has it gone bad? or it needs cleaning?
I resetted ECU but after test driving, it came on again
also where would I locate vacum hose?

 
Rep Power: 811

They are all around, mainly around the throttle body. Just make sure they're all pushed in and clamped. Get some TB cleaner and wipe inside the TB (you can open the valve with the lever to clean inside. Might just be dirty. It could be your tps or map sensor, in which case its new throttle body time. Get the code checked for the engine light first.

code was checked and it said O2 sensor problems
cant remember but I think it was
P0130 O2 Sensor Circuit Malfunction
or P0135 O2 Sensor Circuit heater Malfunction

Then replace the o2 sensors.

isnt it like couple hundred dollors for O2 sensors? ahh.. I guess trip to Honda dealer
one thing I am thinkin is that my dad used my car last nite into town and got 94Octane gas, which I dont normally get. Also it happened after I took the resegenator off for two days and rained today..... this is giving me too much stress

 
Rep Power: 811

Don't worry. Yea getting that gas was a bad idea, but just run it out and go back to regular. o2 sensors aren't that expensive. I think you can even get some from an auto parts store. I doubt its over $50.

gearbox, by re adjesting idle RPM, do you mean doing it by adjusting the tottle cable?

 
Rep Power: 292

02 sensors are a few hundred from Honda. They are cheaper if you buy them from the states but good luck getting them to ship to Canada. I thought the same that they couldn't be that much but the guy at Honda told me different

 
Rep Power: 0

but I doubt it's idle rpm thing tho cause while I was in highway doing 110, suddenly felt shake and rpm dropped. I tried punching the gas, but nothing happeded. or is it just my ECU putting car into safe mode?

 
Rep Power: 811

ya safe mode when the engine light comes on. By idle I mean adjusting the set screw to raise rpms by opening the throttle plate more. It's prolly not that tho cause everything should be computer controled. If you need an o2 sensor I could see how much they are here and ship it to you if it ends up being cheaper.

 
Rep Power: 292

I think it was like $30 in the states and over $200 in canada. I don't remember if it was that high but I remember it being alot higher then in the states.

I will check local stores and let you know the price
Majestic Honda sells it for $35 I think
went out to garage and tried everything but still nothing.
there were one more thing. this ghetto alarm setup by me. I connected some wires to RPM wires but never had problems. I just cutted it out but still having same problem..
maybe I should just bring to Honda or a shop

 
Rep Power: 319

hmm i dunno what that could be. Ive had a cel for my high flow cat for a while and i noticed so drop in performance but my car never dies or anything. I dont know what that code is but check what everyone else said. Maybe you shorted one of the wires by hooking up ur alarm system. How long was the engine light on?

Off topic: viper ur a rep ***** if ive ever seen one "its ur passenger seat....rep please" LMAO...haha

it was on from this morning... O2 Sensor can break with water +hot? cause I have vented hood and water dropps on to the header possibly 02 sensor

 
Rep Power: 811

yea water can ruin it. Why not cover the vents when it rains?

 
Rep Power: 0

hmm because I never had that problem before..
thanks for the help that you are giving me Gearbox

seems like this thread is problem that I am having. I should PM him askin what happened next.

ok, i just read this after i replied to your PM. Check the stuff I told you about (primary O2) but I would also check out your sensor wire that goes into your airbox. (IAF or AIF or something like that?) If you just recently took your resonator off, maybe that wire got pulled out or damaged? Also, maybe try Putting regular gas in there, the higher octane gas could be messing it up. Definitely reset you computer after checking everything out. Pull you negative off your battery for around 10 min and then put it back on, start you car and don,t touch the gas for 5 min.

I got my o2 for around $225 installed last year I think...I would have to look for the invoice.....and that was at Honda.

 
Rep Power: 315

Wonn Young, dude thats SUCKS!!! Try what everyone said, if nogo, than goto Honda. They'll definately tell you whats wrong... but for a hefty price.

Still not working
I feel like Shandon bahaha just kiddin man..

Upd-Ate
It's Moving but something is Fked up. so I went to honda in Bank st. thay are like "OK sir, your car will be looked at on wednesday, 2 weeks later and it's $51 just to check the engine code + $$ for other inspection." said fkit and I went to Ottawa honda, where I usually go and I talked to the guy for while trying to find out whats wrong with it, he suggestes to try find it on my own cause if I bring it to them it's still $51. So I drive around and problem got bigger so went to some random shop (one infront of Bestbuy in Vaniea) and the owner did a testdrive of my car, gave me some ideas and booked an appointment tomorro morning. probly gonna get charged $100 just to find out whats wrong.. I wish I know what's wrong and be able to replace it on my own.. damn it..

 
Rep Power: 319

I feel your pain...i payed the 50 bucks for my 02 sensor problem. Ive had "similar" problems but never has the car died or not gone over 3000. I dont know what to say man.

 
Rep Power: 0

don't go to any honda dealer. you can get the code checked for free at part source. the dealers are a55holes!

can you still drive it? are you coming out tonight? I'll check a few things out for you if you want, or if you are available during the day maybe i can check it then.

does anyone here have a code reader? jim?

 
Rep Power: 563

I wish I had a code reader..

only time I had a problem with RPM's was when the oil shifted in my pan and the VTEC wouldn't kick in due to lack of oil....sorta like a rev limiter....car lurched like crazy.

^ That was on the way up Gatineau Park Rd right.
