: 1993 STS running rough P053 Code

12-03-06, 09:32 AM
I have a 1993 STS that was running fine till yesterday when the car started running rough especially at idle. Can someone give me a list of things to check for a P053 code(Distributor Signal Interrupt)? I have looked at past posts and have seen the coil packs, ICM, plugs, wires and fuses mentioned. Are all these related to the P053 code? I was wondering if a good start was to pull individual plug wires from the coil and see if there was a difference in the car idle? Thanks for any help you can give me
