Hi there, Ive been running open header on my b18c1 for 2 weeks now and started to have an acceleration problem about the 12th day then the 13th day couldnt hardly get th e car to move and it idles like crap. got a code 3, replaced the map, got a code 10 replaced the iat, got a code 10 still(shrugging shoulders)(reset ecu) is it possible the o2 sensor is crapped up because of this? I replaced the fuel filter and plugs. could it be the dizzy? im clueless on what to do now. thanks for any help. right now my car is at a shop and they are going to look at it. Ill tell you monday what they say.

 

I'm curious as to why you are running open header at all.

There are lots of problems with running open header for long periods of time. With an open header you leave the engine internals open to more air. So once you turn the engine off the internals of the engine cool much faster than had you been running a full exhaust. There is a possibility that you have done this.

 

that is a small chance though right? i mean there is still the full lenght of the header(itr) that will gradually heat up the incoming cold air after shutdown. however if this is the case how much damage are we looking at possibly $$$?

I dont want to run open header its just after the swap the cat didnt bolt up to the header and now the new hight flow cat I order for the greddy still wont work with the header. So im still open header. I mean people do this all the time even up to a year and have no engine damage. so I hope im not the few and unproud.

 

well i hear about people ruing open header and messing up there valve seals

 

would the broken valve seals cause a similar problem to this?

damn, u can't run open header?

****, on my camaro I was running open hooker headers and it didn't sound bad at all....didn't know u couldn't do it on these 4cyls...probably has to do with back pressure...anyways.

If it's how these guys described it I would suggest putting an exhaust on and seeing what happens...otherwise change the dizzy...and from there I'm not sure, maybe an O2 sensor.

 

thanks. man all these sensors, dizzy, and whatever else really adds up in the wallet. THis good deal on the swap is quickly becoming a money pit. I was reading in one of the posts to put foil around the o2 censor??? will it work?

Yeah a swap is rarely just the engine, u always wind up paying for extra ****.

 

I've heard of warping valves when running no header, but with a full length header i really don't see that even being possible. its probably unrelated to the open header

 

well put on the rest of your exhaust and reset the ecu and see what happens then youll know for sure whats going on

I really hope your right. although it sounds like something is really bad.

for sure??? I highly doubt it. Car is at the shop now anyway and they cant look at it till 2morrow

 

Open header isnt going to mess up your valves, only runnign without a header will do that. its probably all a huge coincidence.

 

hope on;y the best guy, i ran open full length header for a year and a half and nothing ever went wrong, seriously i love the feeling of the high end you get just worry bout messing up anything.... just the risk i take i guess

 

yep maybe the vibration knocked something loose or out of place or maybe something like the fpr, fp, or maybe the tps is really bad. I checked the tps, new map, new iat. tps read .44 closed and about 4.5v open. that seems reasonable right?

 

y dont u just go to a muffler shop and have them weld the cat to a flange and bolt it up?

 

Yea what he said. You spent the money for the swap and you said you got a good deal on it. Take the money you saved and get an exaust on the thing. A muffler shop will have you in and out in just a few hours. Are you driving this car like this, meaning an open header? You wounldn't get down my street without getting pulled over. GL with the problem.

 

muffler shops wont work on this thing bc of no cat. I already have a greddy evo2 exhaust and a greddy style high flow "CAT" really just another reasonator. and I cant seem to find the right flange that will work with this. its an itr header any ideas on a compatible flange?

havent been pulled over for the noise but did for going through a red light with a loud header

Just an update, these guys at the auto shop are saying the timing belt is loose for whatever reason(tensioner maybe?) belt is pretty new. there is no compression at all and possibly engine damage. they want 270$ for the timing realignment and already charged me 50$ for a stupid compression test. Ya Im out of there like a fat kid in dodge ball. car is either going to my friends house or back to mine for my friend to help me.

You have no idea how pissed I am right now. I need some support you guys!! Youve been great so far!

at least the towing is free (woohoo mom works the tri A's)(AAA) not AA

when i did my swap i had **** like that happen and i cept swaping out sensors with my friends. and then it got worse when i went to obd1, so i replaced the fuel pump it got a wee bit better, then replace injectors with some oem type r injectors and /problem solved

just letting you that i had a similar dilemia, but it might not be what yours it doing

 

ya not exactly(dont know for sure) the same thing. who knows after the timing adj. they might find the engine doesnt still run properly. could be some valve damage or piston maybe what else could go wrong?

 

Don't mean to sound like an ***, but that work that the shop wants to charge so much for is easy **** that I think anyone could figure out...especially someone who works on their car, it's basic ****.

Why don't you get the helms or even a cheap book from autozone and fix the stuff yourself. If it works, you saved yourself a shitload of money, solved the problem, and learned something.

If it doesn't work, you saved a shitload of money and still learned something.

 

na man your right. I even have friends who have done it before and could help me. only problem is when they can help. your guess is as good as mine. and in the meantime the parents are nagging the crap out of me cause im using their ride alot. so it comes down to lack of patience from parents and me not wanting to push that since my *** should be out of the house by now anyway. lol. I would like to learn just not enough time it seems.

 

my god this post is so ******* retarded. a duha duh duha

 

timing reset and engine is running good. im going to ask why this belt skipped in the first place? as long as its not damaged im fine with that
