Just replaced opti-spark, waster pump, plugs, plug wires. Car still runs like crap. Do you have to reset the computer somehow ?

 

It would be a good idea to clear the computer. This will reset the long term fuel corrections, which could be pretty well screwed up if you were running with misfires. Find the "PCM BAT" fuse - end of dash panel 93 & 94, under hood box 95 and up - and, with the key in the "off" position, pull the fuse for 30 seconds, then replace it.

No guarantee it will run any better, but worth a try.

 

Thanks....I am calling the mechanic now to tell him to try it.

 

Time for another mechanic?
