would it throw a code and not make the check engine light come on?

 

It can. First time I had one go south it would only be problematic at low RPM loads when fully warm. No codes, nothing, but the new opti cured all.

 

Awesome I'll run down to autozone now. I just changed the tranny mount for an energy suspension one, the one that was in there was SHREDDED.

 

Autozone can not scan your car.

 

Check the tranny mounts, and maybe even check the bolts on the shifter, definitely check the opti but I do agree with fastbird that it is an odd symptom for ignition failure, but the opti on those cars are wack and can cause all sorts of problems and results of a scan can help point a finger or two..

 

well i guess its good to see hes on top of things...lol

 

Yeah I know Autozone can't scan my car, I just got back, lol. Any idea who can scan an '93? How much are optispark replacements?

 

where do live??? if so i have a matco determinator scanner i am in seabrook,nh border of nh and ma

 

Wow it'd be hard to get much further and still be in the US. I live in Portland, Oregon

 

Would it be worth it to go to the store and buy one of the $28 Equiis readers to have one on hand?

 

you have a 93, you dont have to scan it, if it has a check engine light you can just use the paper clip and flash the trouble codes on your dash, come back here and ask, im sure someone can tell you what the codes mean

 

See my sig. I have every code description and diagnostic chart for 93's scanned
and posted on my website.

 

dude ive got a '93 with a 6 speed in it the car is a trooper engine and transmission wise and ive killed the car at the track mine was studdering at 1st gear and fine in all the others........ive done basically everything to the car myself and kno everything just about i would bet u that either ur distributor is bad bc its non vented or that one of ur injectors is semi clogged or clogged get some of that injector cleaneer stuff and stick it in the gas tank its like $20 if thats not it id go for a distributor.......the 93's are alot more basic then the other lt1's if u need any other help lemme kno my email is snowboarder4601@aol.com good luck

 

The check engine light isn't on

 

I'm just curious, but how does the opti being a non-vented unit have any bearing on whether it's bad or not?? From everything I've seen a non-vented opti will outlast a vented opti more often than not.

I'm also curious as to what makes the 93's a lot more basic than the other LT1's?? Last time I checked, save for a MAF and couple of other minor things it's an LT1 just like the rest.
