I have a 95 z28 with 150k miles on it....i have a stumble hesitation in low rpms...tends to get way worse when the car has been runnin for more then 2 minutes....it sometimes dies when i first start it up but i also have no torque to even do a break stand burn out ....it's running like a pu$$Y!!!! i found a vented opti spark off ebay for 70$ ......its got 15k miles on it and its in great condition...is it worth it?? thanx alot

 

I would probably just buy a new one for about 100 bucks more......just my thoughts

 

You can buy an opti from O'reilly's for $140 and reuse the cap. Or buy the complete unit from Jason Cromer for $200.

 

I would just buy a complete new opti, you dont want to reuse a 150k cap and rotor, you will see what I mean when you pull the old one.

 

Yeah, thast for sure...when i replaced mine, with who knows how many miles on it, it had an inch of grease, oil, and dirt caked on it......REPLACE IT!
