My truck is still running really rough at idle. I was told by Justin at JDM I needed a reburn on my chip for my TR6's. Called back and talked to Sean and he said no. Maybe I had a bad coil or a vacuum leak. I am having no loss in boost so I doubt the vacuum leak. I have no SES light. Could it be the MAF I really don't wanna pull all my "stuff" to have the dealership tell me it is something easy. If I get on it afterwards it will run really poorly. But only for a a little bit then it clears out. But it always has a rough idle liek it is misfiring. But sometimes when i get on it it is smooth as could be. That leads me to think it is not misfiring. Anyone have any ideas>??? Wierd truck. HaHa. Thanks, -Mat- Oh yeah I was think maybe it is running to rich and fouled the plugs>???

 

There is some valve that is near the intake manifold,, i forget the name of it though, but i had a problem similiar, dealer fixed the valve by replacing it under warrenty and no problems since.

I'll try and go find my invoice,, lots of papers lying around here though

 

Thanks toast let me know. I bet if I take everything off it will run fine though. HaHa. Thanks. -Mat-

 

I think the item whitetoast is referring to is the IAC(idle air control) valve. It's bolted to the rt. side of the intake adaptor and has a 'tomato paste size shiny can' as part of it.

It can cause idle surging if it's dirty or worn. Unbolt it and clean it out with a solvent and shake it to see if the vane inside will move freely. A cleaning may solve it if the IAC is the problem. Sometimes it has to be replaced.

Also, what gap did you use on your plugs?

I gapped at .40. I think I may have fixed her though. I pulled the chip out. Started it up it ran smooth. Put the chip back in and it runs smooth. I am gonna take the computer out of the truck 2morrow and tape that sucker in there really damn good. I didn't get to hit it all because it was ****ty here today. 2morrow I will know for sure I hope. Thank you both for your advice I will let you know how I make out. Thanks again, -Mat-
