It sounds like you may have an intake leaking. You've replaced the major components so now you need to look for a possible vacuum leaking. The intake gaskets is the easiest part to check. Get a can of brake clean. While the engine is running, spray the brake clean on the top center of the engine. The engine may idle up or idle down or may smooth out. Try this and see what you come up with. If this does not solve you problem, let me know and I will help you figure it out.

Changed plugs, plug wires, distributor, and rotor. Grounded neg wire for battery. Engine still missing.Not a fuel injection miss, but a miss you'd associate with plugs etc.

Did you check the ignition timing ? It should be for manual transmission 20+/- 2 deg BTDC

automatic transmission 20+/- deg BTDC

FYI---One time i dropped a new plug before i put it in and did not realize that the gap have closed up and started a bad miss..make sure all plugs are gaped correctly....could be something else but you can start here...Hope this helped ?

Replaced plugs gapped @.035, wires, distributor cap and rotor. Have new distinct miss w/ gas firing out exhaust

Make sure all of the wires are on good if you have the 4.0 that #1 plug behind the altanator can be tricky, just make sure you hear a click on both ends

Motor missing on my 1995 3/4 ton chevy truck. Replaced wires, plugs rotor distributor cap and coil. Still misses

compression test the cylinders... could be gasket / valve leakage so its worth a try. if low readings on any cylinder then remove head to find out problem.

1996 chevy k1500 misses at idle and backfires while driving when you let off of gas. Changed plugs, wires, cap, rotor button.

Try cleaning your MAF sensor, and check your IAT (intake air temperature). A dirty MAF sensor can cause your engine to run lean and a faulty IAT can throw off your ECM's program causing a conflict to your timing and fuel injection pulse.

Thank you for using Fixya and good luck.

1998 chevrolet k1500 4wd. 5.0 liter.truck runs fine untill putting load on it.Pulling trailer uphill on long grade it starts to shake and miss.If you stay in throttle long enough service engine soon light...

Your ignitoin module may not be able to handle the work load anymore. If it gets hot, it will miss. You'll need to replace it. If you do a lot of towing, I suggest a performance unit from ACCEL or MSD
