How about all the other sensors? Verify EVERY sensor, verify computer outputs--timing advance, etc.Vortec 5.7 from 1998 K2500. now it stumbles and backfires with low power. No check engine light or codes.
Fuel pressure looks fine. New fuel. Put scan tool on and watched live data for O2 sensors and they appear fine.
Aluminum is an excellent conductor, better than brass. Aluminum is used for electrical wiring when copper is too expensive--for example, the 50,000 volt high-tension power cables that go across the country.Not likely! Start with a good cap and rotor. They are known to burn through internally and crossfire even though they look ok externally. I personally have had the best luck with MSD with brass terminals. The aluminum terminal factory ones are a terrible piece. Aluminum is a poor conductor and it overheats the insulating material, breaking it down.
I'm not sure that my code reader can see individual misfires. It did tell me a specific cylinder when I burned through a spark plug wire.How about all the other sensors? Verify EVERY sensor, verify computer outputs--timing advance, etc.
Don't look for misfire "codes", look at misfire counts for each cylinder.

The issue is that aluminum is more-likely to build up corrosion where the arc jumps from the rotor tip.
The Vortec caps are particularly succeptible to cross-fire, due to having the high-voltage pathways crossing each other inside the molded-plastic of the cap.
Exactly aluminum oxidizes, becomes a poor conducter, gets hot and causes stuff to melt. Had a house completely rewired to rid it of alumimum wiring before it burned to the ground.How about all the other sensors? Verify EVERY sensor, verify computer outputs--timing advance, etc.

Which is the better option for you?Don't have access to one.
My code reader has some live data usage.
I was hoping to get some things to try before sending it to the shop. Definitely not opposed to sending to my favorite shop but they only get stuff from me if I can't figure it out. If it would just give me a code as a starting spot, I would probably have figured it out. I am pretty decent at general stuff but this one I just don't know where to start.Which is the better option for you?
Get a usable scan tool system, or take it to a professional?
