What engine do you have? How many miles are on it and when was the last time you had it tuned up?

I had the same issue with my 88. i went thru the whole ignition system but it turns out there is just a bad ground in the harness what i did was just have a ground from the battery to the core support and that helped bring the ground back to the battery. if you have a distributor module give that a shot sounds crazy but its the hole ohms law B.S but it works

I had the same problem with my 1988 F150 for a long time. Had several places look at it but no one could find the problem. Finally had a mechanic tell me to get a new set of spark plug wires. That took care of it for a while and then I noticed that the engine heat shield around the spark plug locations was missing on one side of the engine. It kept melting the same spark plug boot after only running a few miles. I had the shop who left it off replace the shield and the problem never happened again. Hope that helps you. It nearly drove me crazy.

Some general thoughts - -
when you try to accelerate, a couple of things happen. The engine shifts sometimes, and you put it under a load unlike when it is idling.
Is it possible a wiring harness or a hose is moving when you accelerate ? Is it possible the fuel pressure or ignition module is not good enough to handle the engine under load ? Is the EGR opening early or something causing a vac leak and a lean fuel mixture ?

Why my motor miss during acceleration?


MISSING CAUSED BY MANY THINGS LIKE BAD SPARK PLUGS, WEAK IGNITION COILS.STOPPED UP FUEL FILTER OR FUEL INJECTORS.WEAK FUEL PUMP.CHECK FUEL PUMP PRESSURE SHOULD BE 44 - 50 PSI.LOW CYLINDER COMPRESSION CAUSE MISSING.

Random cylinder miss firing. i changed coil packs


Have you changed the spark plugs. I recently changed mine in an expedition and tried using the E3 plugs which were about $56. I don't see any mpg difference but I can tell a difference in take off or during acceleration. My opinion is go back with a basic OEM or Bosch platinum. Also make sure that the COP is seated good on the plug. I would also recommend using an Di-electric grease to coat the inside of the COP. Hope this helps.

Swap the coil pack to another cylinder if it is individual. If not, you should be able to pull the wire away from the plug and hear it fire. If not, you have a bad coil. If so, I would look at doing a compression test and possibly a leak down test.

Intermittent engine miss


There are to many things that can cause the miss fire and when does it happen?? During acceleration or idle. Here is a link for you to retrive the DTC codes and hope this will add some light to the end of the tunnel. http://www.troublecodes.net/GM
Good luck and keep me posted. Did you try cleaning your MAF which can cause miss fire if your engine is running to lean.
