Car runs perfect normally, but sometimes after a couple of hard pulls it has trouble idling and sometimes dies. It always starts right back up with no problems.

The car never used to do this so I dont belive its something with the tunning. My bet is I need to change my plugs, but while im waiting for a new set to arrive I thought I would ask. Currently running BKR7E's @ .024 gap. They have been in the car for 500 or so hard miles.

Thanks,

i think you are correct on the plugs, on a hard run on the decel they may be loading up a little.

Any pain in running the plugs until the new ones arrive besides degraded performance?

hmmm... im no d series guy, but im running ~16 psi on a t3 60-1 @ 9000 rpm with a bone stock ignition and plugs gapped at .030. Unless your running really rich (which according to ur dyno your not) a full boost run should clean off the plugs.

What is your AFR when its stumbling?

platinum00

Not sure on the A/F. I dont have a wideband installed unless tuning. The narrowband is useless but it say RICH .

im going to let someone else chime in here, i dont want to tell you the wrong thing. But reasons like this are why i keep an extra set or two of plugs around

platinum00

With ya... what are you thinking with the A/F.

The plugs were gapped so low because I was having serious issues blowing the spark about above 24psi.

thanks for the help

i am gapped either .018 or .020 cant remember, but i was blowing out the spark at 28 psi as well.

yeah .024 is not that big of a gap i run .020 on my DD, it stumbles a lil after hard pulls idling but it doesnt die or anything....

I would wait for the new plugs...

got them today. seems to be better, but its raining so i cant really get on it.

Ran the car pretty hard today. Put about 150 miles on her

Idle is still not heathly sometimes. I cant really find a pattern to it yet.

Could the IAC cause this? I guess I need the wideband hooked up to see what the A/F is.

its possible that something under heat is twisting/warping causing a leak, or a bad pcv vavle

Maybe, but its random and normally if I shut the car off and turn it back on idle is perfect again. PCV system has been removed and replaced with catch cans.

I will try and check my vac hoses when it happens again and see if I notice a leak.

Thanks for the input, keep it comming

I've had this same problem with my car for a while now. I've put new plugs in it and replaced every vacuum line on the car and it still does it. I turned the idle up to about 1K just so I wouldn't have to play with the gas so much at lights.

That's weird. I idle very well after runjing hard, but just cruisin the idle is a lil bumpy at least til I hit v-tec a few times then it purrs like a kitten at idle. Very confusing and sometimes frustrating.

mine does it too. i just let car coast in gear and quick shut it off and turn it back on again.

platinum00

well I decided I need a new paint job, so the car is ripped apart again. No glass, moldings, lights, etc...

Might be a couple of weeks before I get her done.

If no one has a solution, I will buy a Wideband and post of the readings to help.

It sounds like a couple of people are having this problem, so at least it's not just me
