Well a while back, i replaced the opti because the car still had a high RPM miss. Then a few days after that, a coolant line leaked onto the opti...a week after that happened, the car ran like crap...the whole car shook at idle, acceleration, everything. I could see every single spark plug arching at night. Took off every wire and checked with a digi multimeter, all were fine. Also no signs of burnt wires. So I assumed it was the opti. I put in another opti(that was used, but was fine when it was taken out)...and the car acted exactly the same(except for now the SES light is on)

You think I just have 2 bad optis and should get a new one? Or does that sound like something liek maybe a opti harness?
I cant find any bad grounds or anything. What should I do? Anyway to test for a bad ground?

 

First off, put in some new wires. Just because they're not useless or anything, or check out fine on a ohm meter doesn't tell you a whole lot except that they are working, but with high voltage ignition, instead of the kind of puny ohm meter, your sparks are going everywhere to the plugs (as in your electric light show)

It is possible to have two bad optis, it's happened b4, but I'd change the wires b4 I went through all the work and expense of opti again, at least see if it helps. New wires can never hurt.

Keep us posted. --JBird

 

i had a torched wire and i think that when it grounded to my car it screwed up my opti, cause i replaced the messed up wire and its still doing it.

but im going to replace the plugs and wires.
