Formula still running really rich alright well im in the shop right now typing on his computer... and so far we've figured out that the car is running ridiculously rich. we pulled the drivers side plugs off the car and they were completely black, so we just replaced those plugs for now and when we put the new ones in it didn't help at all. the car sputters at idle and sometimes just dies out of nowhere. the left o2 sensor goes anywhere from 0.024 to 0.9xx and the right o2 didn't ever drop lower than the 0.024 but it seemed to run just a little higher than the left o2... we unplugged the left o2 thinking that it would be the problem and it still ran terribly. tried unplugging the MAF and still ran terribly. checked fuel pressure and it was fine. we have to have the garage door open to even run the car and it still fills the whole garage up with a gas smell. so far the only codes we have gotten were from trying to run the car with the MAF unplugged and the o2 sensor unplugged, but nothing else is coming up.
one weird thing was that the EGR was always at 0 and never moved, even while giving it gas, so we weren't sure how it really operated or when it should open or start working....
i replaced the distributor with a delphi one from thepartsladi on ebay because the car was backfiring badly and one day it just randomly died on me going down the road and wouldnt restart till i came back about 2 hours later, and before that it would take forever to crank to start and basically all the symptoms of the opti failing.... and the rotor screws were backed out of the one that was in it so i figured that was the whole problem... but it wasn't the case
we've traced and retraced the plug wires to make sure they were gonig to the right spots and they were

k you think that they would all be leaking or what? like would only a few leaky injectors really make a car run that rich?
man i wish i could hulk smash the whole damn car right now lol
this just doesnt make sense... could i have just gotten a faulty distributor or something?

. k so today i went and took a recording or whatever you want to call it off of freescan.... so i don't know if this will be much help to me but i have one of it just idling (or at least trying to) and then one of a couple revs just to see if anything looked out of the ordinary.... so if anyone reads these and sees anything messed up let me know
also, it said i had thrown code number 16, which said it was "low res" which i thought was an opti code, but i wouldnt think my new opti would already be messed up... so it may just be an old stored code that just came up.... but the check engine light wasnt ever on...
actually, is there any way to post an excel file on here? i cant figure out how to do it and i searched and it gave me a fast and furious thread lol

anyone know if thepartsladi on ebay is bad to deal with because i def. got a faulty distributor... finally my car threw a code today for the opti, so we are going to take it off and hopefully i can get an exchange from them.... don't really care to get my money back but i would def. like a new delphi distributor.... so i really hope they aren't a hassle to deal with

I would also check to see that your opti wire harness is not dirty or damaged. I think that could cause your code as well.

electrical harness 12106559 $55.19
But that part number doesn't come up anywhere.

hmmmm.... yeah on gmpartsidrect it says its like $300 lol.... you think i could just clean it with some electrical cleaner and it would be alright?
also, i finally found the number of who to call for thepartsladi and called them.... seemed like really nice people and said they were sending me a package tomorrow to send the opti back to them in and would send me another as soon as they got that one back... so im happy with the deal

What were the ECT sensor readings from the data log? If they are on the low side, that could make it run rich. Just another idea...
And EFI connection has optispark harnesses for $30 if you do need one.

hmmm.... yeah i do need the MAP but i dont think the TPS.... do you know off hand which one is below the MAP on that side?
or is the TPS actually it?
scratch that... just figured out what i was lookin for... i think that TPS pic on shbox should say left hand side of the intake and not right cuz you can see the TPS in the MAP pic...
but yeah i just ordered $65 worth of connectors so i should be good to go now lol
