need help

[ElectronBlue]

K this is my problem hoping someone can help me out..

Well my car is running fine and everything... its the spark plugs and ignition wires are fine even doubled checked with my old ones... this just started to happen now... when i step on the throttle and open it wide two fast it laggs like crazy and doesnt want to gain any rppms it like studders at a certain rpm.. just as if thers no fuel.. i checked and fuel pressure is fine and everything.. but if i ease into the throttle the car runs fine... My thoughts are it could be a Disty problem or fuel filter... any input??

I had this problem. It turned out my disty had weak spark in higher RPMs. I have no idea how to check for this. I Gave in, bit the bullet, and took my car to the stealership, because I'd used ALOT of time trying to figure out the problem.

Right awn!
Unless yours is a brand new disty, you should do the HEI mod.
If it is brand new, you should do the mod to the old one, and keep the good one just in case.
