94 Pontiac Missing Sign up here!

Had some problems with the ignition control module and coil packs a few months back. Replaced both and fixed the problem for the most part. Plug wires and wiring were all good as well. Missed every once in a while but not constant like it was. Now it's starting to miss again. It's not as drastic as it was the first time. Very subtle almost like driving on a rough road. It doesn't miss if it's in park or neutral and idling or if you rev the motor up. It only does it from around 45mph and up and only if I'm accelerating. Possibly injector or spark plug related?

Are you sure this is engine at all? Try duplicating roughness/missing just in drive brakes on hard duplicating the load just a bit - don't go nuts and in a safe place. If nothing it may not be engine at all, T Hammer Time Ultimate Carjunky / Moderator Feb 19, 2014, 9:35 AM Post #3 of 3 (1135 views) Re: 94 Pontiac Missing Sign In Yes, it could be either of those but the first step is identifying which cylinder is doing it and that won't be easy because OBD1 doesn't track misfires. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
