It through the code P0300 which is a random cylinder misfire. I have platinum four plugs in the motor. I have also tried changing the ignition control module, which didnt work. I don't see any spots where the wires have arched. If the A/c is on the problem is worse, as well as going up hills. I am not sure what it could be. Has anyone had this problem before? Anyone know what it could be. Someone told me it might be the PCM, but that is pretty expensive to replace. If anyone could help I'd Greatly appreciate it. Thank you all very much for your time.

Anyone that uses the plat 4 will have them problems.
Pitch the plat 4 in the trash can and get the good Ac -delco plugs the ac -delco book calls for.
If that does not do it post back and someone will help you.
