Ok Guys IA just want someone elses option on this. My car is hard to start, It cranks fine, but when it fires, it stumbles really bad for a few seconds then the rpm hols steady @ 2 Grand. When driving i have to keep a LIGHT foot, anything more then 1/2 throttle it will back fire and pop BAD along with lost of power. I have a set of new MSD wires and a set of Rapid fires I am going to put in tommorw. Should I change the opti-spark too? From what I read in my search that is a CLASSIC TELL TALE SIGN. Am I correct in thinking? Thank Once again, John

 

Yeah it sounds like your opti. But before you replace it i would do the wires and plugs first. Also i would check you coil out. If all is good then more and likely its your opticrap.

 

scan it and see what codes are there if any,Jake

 

Opti, number one lt1 problem since the beginning

 

I was wrenching all week end. Plug 2 ,7, and 8 were ORIGINAL!!!! the wires were too!!!! I changd the Blugs ( Bosch Non Palt.) MSD 8.5 wires. Coil ( MSD), Ing. Moudle, Dist and Opti spack.. IT RUNS LIKE A RAPED APE.... WOW.. Thanks Guys

 

heh i know what u mean i just pulled Bosch supers outa mine, and put all new wires on and damit, it runs like the worlds coming to an end

 

Glad you fixed it! Sure feels fine to have some horsepower!,>Jake
