Ignition breakup revisited
Since the summer I've had an ignition breakup problem. It only occurs under full throttle, at full boost (~8 psi). It will occur anywhere from 4000-7000 rpms. Basically the car will misfire for a moment, then feel fine, then misfire. When this happen it really slows the car down due to the lack of smooth revving while under boost. This only happens SOMETIMES. Sometimes it will pull nice and hard all the way to redline without a single problem. Here are a few things I know
1. It's not my bin
2. Not the distributor/ignitor. I swapped the entire distributor for a known good one and the problem still occurs sometimes.
All I can think of is maybe the plug wires. I was thinking that it couldn't be them because it only happens under full boost, but then I realized it could be happening because of high rpms, because I'm only in high rpms when under full boost.
Anybody else think that it could just be my wires? I don't wanna spend $50 to try it out and find the problem is still there.

hmmm just ohm out the plug wires, then youll know if those are good, the specs are right on the side of them of tolerable ohms, and i second the plug idea, temperature?, gap? seems funny that it peaces the ---- out at high rpms, sounds like a plug temperature issue, but hey could be the plug wires, get that ohm meter out

Re: Ignition breakup revisited
jago i had a similar problem back in the day with my old d15b vtec
when i floored it it would lag for 2 seconds then be fine
if you hold it at full throttle long enough itll go back to normal and it will only do it once every startup
I never found the problem but I would check the tps.
Are you throwing any codes? I never knew if i had codes because the person that sold me the car had unhooked the cel.
Plug wires do no solve the problem...
