Chevy Suburban C1500 5.7L-Misfiring gets worse as vehicle heats up

Asked by Kaceycole85 Mar 17, 2021 at 12:38 AM about the 1995 Chevrolet Suburban C1500 RWD

Question type: Maintenance & Repair

I've replaced the computer, just about every sensor you
could think of, fuel pump, fuel lines/filter, the 2 fuel
injectors, and probably a couple more things I can't think of
right now. Thinking it could possibly be something to do
with the exhaust(clogged catalytic converter), or maybe the
coil? Looking for ideas of what I should replace next.
Thanks in advance!

What about spark plugs, wires, or distributor cap and rotor? A clogged cat will cause a bog in power not a misfire.

Yeah, I did all that too. Hmmm... Wondering if it's the coil or something in the motor then. Replacing coil and whole exhaust next.
