I did the swap about 5 monthes ago and at x mas i got a got custom burned chip and it ran great up until here recenly. i have the 350 injectors and afpr. i checked the plugs and wires and the plugs are browna dn the wires appear to be fine they are about 2 years old. but my problem is that the thing feels like it has a dead a$$ miss. i can't figure it out. it only does it when i give it more than half throttle but when i put it on first gear and romp it from about 3000 rpm it doesn't do it. what the heck could be by problem. it seems to me like the computer is screwing it up but i have that chip to fix it and it was fixed up until here recently. could it be that the warmer weather is causing it to run lean and i need to bump up the fuel pressure? thanks

 

Did you check for error codes, yet???

 

do you still have the 305 knock sensor in there? is it a flat tappet hydraulic cam or a hydraulic roller cam? Is the distributer in the right tooth? Is the cat clogged
