Def a large spark plug gap, I think stock is .050 area?

That plug gap is way wide.

That is probobly a HUGE part of your problem. either re-gap or replace them

well guys it gets WAAAYYY better now....i replaced all the plugs with ngk tr55 platinums gapped at .050.. hasnt acted up yet the way it has before on a short 25 mile drive. it is cold out though. BUT, halfway on the ride the service engine light came on. when i got to where i was going i shut the car off for a minute or two literally and turned it back on, no service engine light. get halfway home and bam service engine light comes back. get home and go to flash codes and the fans turn on etc but the service engine light doesnt flash it just stays lit. this is really puzzling now.

certain codes can cause the ECM to ignore all sensors and it will kick the fans on. When I had a LT1 camaro I had a MAF code and it did that

yeah I just read about that and that I can't flash codes on the 94 I need a scanner or aldl cable... Lovely.

Still getting new icm though tomorrow hopefully. Anybody have the ability to scan this and live kinda close?

the jump the pins trick doesn't work on that?

do this: http://www.extreme-check-engine-ligh...%20Decoder.htm

You should be able to get one of the parts stores like Autozone to scan the codes for you for free.

Already did that...doesnt work. The fans just turn on but the service engine lite stays lit no flash or nothing. I looked it up and found that 94-95 Lt1 you need a code reader or aldl cable

The local advanced and autozone don't have the obd 1 scanner to use

You are correct, its obd1 and you can only read codes with a scan tool.

Free for the first 20 uses.

If you wanna buy a cable, lemme know.

Thanks bill and Ltb1ow you have another pm

Can you verify if you have a 12 or 16 pin connector?

a 94 can have either, I think, 12 pin being able to let you jump pins to flash the codes and 16 being required to use a cable.

12 pin still doesn't let you...and that's what I have

Ach, that sucks, my cable is 16 pin for a 95. Sorry

Thata what you need. I had to buy one form a member on here for my 94...and I downloaded datamaster for free. You get 20 recordings for free. Its a piece of cake to install and easy to use.

Thanks guys I'm gonna have to wait till Wednesday to order it and then for it to get here

Actually that's still the wrong cable I need the 12 pin one I swear I always get the car thats special

That one

yup thats the same one i found. thanks again.

took it for another 15 mile ride, ses light came on about 4 miles in, shut car off for 2 minutes, drove home and 4 miles into that ride ses light came back on. car seems to be running fine otherwise....

:scratch:

i gotta get that cable...

starting to think maybe a computer issue...

now the schizoness is back....only things i touched on the entire car tonight was i fiddled with the egr to check its operation and it checked ok, literally unplugged and plugged back in knock sensor and coolant temp sensor for computer, and touched the passenger side o2 sensor since the white wire that has the ground band that wraps around the sensor seemed fishy. now, no check engine light, tons of missing/backfiring.
