Well, my stock waterpump started leaking on my opti so I decided to try to fix everything up on my own. I guess that was a terrible idea.

The car was running great for about a week after I fixed it and there were no leaks. The other day the opti started misfiring again, checked the coolant level and sure enough its low.

I have not had a chance to look at what leaked yet (hopefully just a hose) Do you figure my new opti is pooched? (Car is a 94, so it's NOT a vented optispark)

Might it survive if it 'dries' out for a bit?

Thanks!

 

Doubt it's bad.

 

How do you know for a fact that "the opti started misfiring again"?

 

Same symptoms as I was getting with the old opti. Car ran perfect for about a week after replacing the waterpump, then it started leaking again.

Low RPM stutter, idles poorly, no power at low revs, if I give it to much gas at low revs it bucks. A shop diagnosed the first opti failure, I did the labor to 'fix' it. Unfortunately, I guess I did something wrong.

 

Check the connections on the opti itself. It is possible that the rubber seal on the connector may have allowed coolant thru. That can cause misfires also.

 

Crap. I let the optispark dry out for a few days. Still misfiring horribly.

Just dropped it off at the shop, I'm looking forward to paying for something that I tried to fix but screwed up

Big boo at Chevy's design
