    Mine is doing the same. My fuel pressure is correct. I put a new camshaft position sensor and still have the same misfire. Verrry frustrating!! Mechanic said maybe the brain is at fault.

I've got the same problem - turned out to be the CSFI (a.k.a. the fuel spider assembly). GM put these piece-of-trash units in their trucks from 1996-2000 and they get coked-up with junk from the gas tank so the central electronic unit will actually shut off the cylinders one-by-one. Get it replaced - don't even bother trying to get it cleaned. It's expensive either way. But by getting it replaced you'll actually be upgrading it since the original units are no longer sold (wonder why)... You can get them cheapest from GMPartsDirect.com, or you can Google "CSFI to MPFI conversion."

My 1996 chevy 1500 has a missfire i have


Well, First i would have replaced all of the spark plugs and the wires, Then moved to the cap or rotor second, but in that case, did you check the spark plugs and wires, when was the last time they were changed? Maybe they were changed already and that's why you when straight to the distro? Is there a computer code for a misfire, or it feels like a misfire when it's running?

Start with fuel system. Listen for fuel pump humm at fuel tank No humm check wiring to pump for power. Then check for spark at plugs and wires. Remove wire from coil and hold near engine and see arch when you crank. No arch. Replace ignition Modular inside distributor cap or cap or rotor

1996 Chevy Express 1500 w/5.0 bogging only when warm.


The cylinder 7 misfire is likely a symptom of the problem, not the problem itself.

Typically, the catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream 02 sensor reading should be fairly steady. Typically the P0420 code triggers the check engine light if the readings of the two sensors are similar. This is indicative of (among other things - such as faulty sensors in the "emissions loop") a converter that is not working as efficiently as it should be.

I do not believe that it is a problem with a valve/head gasket or cam.
