First . The car has edelbrock performer heads, e303 cam, headers and an offroad x pipe. I have replaced the tps sensor and PCM. I cleaned the mass air sensor and idle air control.Its got new msd coil, plugwires, cap, and rotor. Its got new NGK plugs.
Now to the problem.
When the car is cool it skips very bad. It clears up "mostly" when the engine reaches operating temp but it skips sometimes too when its warm.
When i press the throttle to the floor. It comes completely out of the miss and runs great.
I tried to pull the codes from the computer but got some garbage think maybe i didnt do the test right. I got a code for the 4x4 switch was broke. I know thats not right. Some help doing the computer test will help to.
Thanks
