There must be an issue somewhere if you keep blowing optis, i run my car to 6500 a lot, and have a lot of track passes on my opti. I've only had one go out on me since ive owned the car (3 years)

 

yea my car sucks lol, I need to either find someone to look at it or sell it as is, I have no time with school starting up.

 

What do you gap your plugs at? You might want to close up the gap a little bit and lessen the resistance.

 

my last set i had at.046 i put these at.047

 

lower it down to .040 or run .035 like i do, it will make it a little easier for the spark to jump.

 

Might want to look at the tune and lean it down at idle and just above idle.

 

You can tune the car to stay in open loop at idle, therefore being able to adjust the a/f, but off of idle (moving) is going to be closed loop and isn't adjustable.

 

it was tuned by pcmforless. I just went on a hard run and she ran perfect as far as plenty of power and no misfires... but i did throw a ses light solid this time, i will have to go and get it checked out. maybe i fouled an o2 sensor or my mass air flow sensor when i was having all those backfires. If it is a question of tuning i will send my pcm to bryan herter (pcmforless- tuned by them as of right now) and get it leaned out... he can do that right?

 

If this opti blows i will be closing the gap on my next plugs, or if i get a lot of miles ont hese plugs i will close it in on the next plug change.

 

what would be the advantages of that? Would it kill my gas mileage? and would she even run well?

 

I was just stating what you COULD do. I honestly don't think you need to take that route and that something else is wrong with your car. Keep digging, you'll find the problem. The only way to get information from the O2's is the know your short term fuel trims when the car is missing. That will be an indication of something. It has to be something that effects both banks to foul all the plugs (ie coil, opti, icm, pcm, etc.)

 

it is no longer missing... when i am up at college tomorrow i will try ro find time and get it scanned to see what the code is. i had a joy ride last night and she ran perfect.

 

Ya can gap the plugs at .035 with NO ill effects. That will save your opti also.
