well i guess i fixed my stubbling/hesitation problem that ive battled for 2 weeks now. new plugs, wires, iat sensor, opti, cleaned maf, multiple fuel injector cleaners and tanks of gas, and i still had the problem. so after some brain-storming with my mechanic we pulled off the wire that runs to the opti and plugs up by the #2 injector. i guess its called a distributor jumper wire? the wires on the end by the opti were melted and plastic connector was cracked, apparently to much heat.

so i went to a local gm dealer and shelled out 120 bucks for this stupid wire, atleast i got some vasoline out first, jesus. but now the car is running a lot better, maybe this was partly the cause of the low dyno numbers? ill post the part number later, if anyone may need it.

 

you're not talking about the coil wire are you?

 

no its not the coil wire, ive replaced a few of those. ill get some pics and a part number, gm called it a jumper wire. its on the passenger side.

 

might want to put a plastic wire conduit around it to prevent future occurances. I'm gonna go look at mine now that you mention this! LOL

 

You could have paid about half of that if you would have purchased through one of the GM parts contacts that are posted on this board all the time.

 

believe me shoebox i know, but i had to have it!!! daily driver.

 

A call to Jason or Dal with the words "overnight" would still have been cheaper.

 

thanks ill keep it in mind when i order my knock module!!!

heres a link to the picture of the end of the wire, the part number is 12130319 this is for 95-97 lt1s. my buddy has a 93 and his was different.

Anyone have pics of where this comes out of the opti and where/how it hooks back into the area near the #2 injector?

 

Nevermind, Shoebox had a pic up, and I just didn't know what I was looking at/for.

It plugs into the opti at the top, just back of the water pump. The disconnection clip can be reached with a longer standard screw driver, and the opti half can then be easily pulled off.

It is about 4 inches below the IAC connection, shown here:

The other end connects near the EVAP solenoid. See picture:

Thanks to Shoebox for the wonderfully helpful pictures, as always!

 

I dunno about 95+ but the 93-94 had a choice for the harnnes. either the full one like you got or a pigtail that you crimp for about 40 bucks cheeper
