Ok I took my 02 ex to the dealer b/c it was running bad. It stalls and sputters at about 2000 to 3000 rpms when I'm just crusing. They have been looking it over and think its the egr valve. My check engine light never came on. If it was the egr would my light come on and does this sound like it could be whats wrong??

Find a new mechanic. EX's dont have EGR valves

you sure?? http://www.7thgencivic.com/forums/sh...&highlight=egr

It's an important part of the emissions control system. Most likely the light would have come on. If you find a place that has an odbII code reader, have them plug it in and see if you have any codes stored in the ecu.

Ok. They still have the car so I'll see what they say about it tomorrow

Without the check engine light on, the dealer tells me to go home and there's nothing they can do. In a way, it's very hard to isolate the problem you're having without a code. It could also be related to a number of intake sensors like iat, iac, tps, etc. Or it could be the egr or something totally different.

Have you done the obvious stuff like air filter, fuel cleaner, plugs, and that stuff?

had plugs not too long ago when the problem wasn't so bad. It didn't seem to help any. Got some chevron with techron and it didn't help. I've got a CAI and the filter seems pretty clean its not too old. Hope they will figure something out b/c they warned me it would be $90 for the diagnosis

not all problems with EGR will light up the check engine light. there had been a few cases where the 7th gen civic sputters and jerks, without any engine light and error codes.. but just a change of EGR solved the problems.

I once had sputter problems and it was narrowed down to faulty EGR and recent, the jerking problem resurfaced. our local dealer took 1 and a half days to find out that the injectors are choked. the symptoms are very similar in both cases, with the car jerking at cruising rpm.. EGR usually (not always) comes with the check engine light, but the choked injectors don't.

hope this helps.

Are you sure that you quite possibly might not have gotten a bad tank of gas. That has happened to me and others in 7thgens. Possibly even carbed up 02 sensors. Maybe the EGR valve. It can be a number of different things.

Honda just called and I got the samething you said gearbox. "We can't figure out what your problem is. You've got all this performance stuff and it makes it harder on us" (CAI, a/f gauge, and alarm are the only different things about under my hood from every other honda they see, makes for a good excuse) They said they wouldn't charge me for it though. Now I've just gotta see if it will make it to my parents house. One of my buddies dad is a mechanic there and I know he'll try to figure out exactly what it is before he just jumps in and starts swappin stuff

Oh and thanx for all your advice. I'll pass it on to that guy and see what he thinks

 
Rep Power: 813

I bet it could be the a/f gauge. Those things have been known to screw up O2 sensor voltage. Check the oxygen sensor.

 
Rep Power: 286

ugh yea I thought about that. I didn't know if they ever messed anything up. I also hooked up one of those stupid *** vtec lights. And about where the light comes on is around my problem. I'll watch the light when I get my car and see if I can find a connection

 
Rep Power: 813

A vtec light should help you determine if the problem is with the vtec system (like solenoid, ecu, etc). It should come on between 2800-3000 rpms depending on throttle position. Take off the air/fuel gauge and replace the O2 sensor if it's bad.

its not an excuse, its just the truth. mods make troubleshooting problems a pain in the ***. it creates many more possibilities on what the hell could be wrong and caused the prob

I went and talked to a performance shop earlier today and a guy said it sounded like an O2 sensor. He said b/c it was running lean when it was doing it that the O2 sensor was probably bad. He said that it could be reading lean then spraying the motor with so much gas it won't spark right. It does backfire a little too and it could be the extra gas being burned later. I thought I remembered reading on here that an O2 sensor would cause the check engine light to come on but he said it wouldn't always. His wife's car had the same problem so he knew what to look for. Having a torn apart rx7 and a few crx's and some other imports sitting in there my guess is he knows what he's talkin about and I'll probably trust him over a n00b postin something. Thing that sucks the most is he said they run from 100 to 250 new I'll let ya'll know what I find out. Thanks for the help

dude, an o2 sensor cost $37 from http://www.hondaautomotiveparts.com/

$100 - $250 for an o2 sensor is crazy expensive! unless its a wideband! -- Jeremy

i have a 2001 ex. Mine started sputtering on me about a month ago and i blew it off. It only happened when i was at constant low rpm speed. well the other day my check engine light came on so i took it to autozone they gave me a code of 1491, but they couldnt tell me what it meant bc it was a "dealer code". So i took it to the dealer today and they found out that my EGR valve is bad. So yes vtechs do have egr valve, the only bad thing is that it cost 1 bill for the part. Labor was going to be 120 bucks but i told him i can do it myself. Now i have to find some forum that tells you how to change an EGR valcve. If anyone has a link please post need it in a couple of days. If any other questions feel free

All Hondas suffer from stuttering and jerking at low RPMs under light load. Happened to my '02 Odessey at about 30K miles. One dealer said nothing was wrong, another dealer said it was a common situation and they all did it and there was nothing that could be done. Finally, after many discussions on the OdyClub forum http://www.odyclub.com I stopped at another Honda dealer and told them to change the G*D* EGR valve. By then, it turns out that they had a service bulletin describing the problem to a "T" and changed the EGR valve under warranty.

I would guess the i-Vtec engine in the Civic is of the same basic design and they ALL have EGR valves! Change it, it will solve your problem!!!

Our D17 is a VTEC-e not a i-VTEC. It's a lean burn with VTEC on the intake side and the engine runs 1 valve per cylinder for the first 2000 rpms and then goes to 2 to redline. You know, for your info.

Changing the EGR solenoid is a very easy procedure. Its located on the passenger side of the engine right next to the thermostat housing. Its the large black canister with a plug on the top. There are 2 (i think?) 12mm bolts that hold it on. You'll need a gasket scraper and a new gasket too.


edit: I think they're 12mm.

well i just bought a a/f gauge , does it end up messing my o2 sensors?

 
Rep Power: 0

It can, I would'nt use an A/F gauge unless you use a seperate O2 sensor for it.

I've had one on for almost a year and it hasn't done anything to it yet... YET..

who said theres no EGR? Are they stupid or just retarded?
