I could use some insight on this problem. I just put all new plugs and wires on my 96 Z28 after having alot of missing and severe hesitation all across the rpms. Now it acts like it wants to go but still have a ton of hesitation and missing out. Is it the dreaded Opti or something else?

Any backfiring? Possible crossed wires and/or cracked porcelain on the plugs.

u say it was misfiring before u did the plugs and wires too???

rgemtb492

The backfiring was minimal. Only when its up to temp. It was misfiring before as well.

It started about 200 miles after a new set of plugs. I had E3 plugs and afterwards heard they weren't very good. So I did all new plugs and wires and there is no change in how it runs

sounds like it could be something else........and yea the e3's are garbage.....my old HCI 355 misfired with them in it i drove it to the end of my street came home pulled em out and threw em in the garbage............a $3 NGK runs great lol

It has $8 NGK's and I was hoping it would solve the problem. I'm trying not to admit that it might be the Opti. But, it is seriously leaning in that direction!

How many miles are on the opti?? It could just need a new cap and rotor.

I did the cap and rotor about 5 yrs ago or 15,000 miles ago.

Hmm... have you tested or even try swapping icm & coil ?

rgemtb492

I have not. I'm just compiling a list of ideas on what it might be.
