The 5.0 in my crawler started backfiring, running rough, and very little power the other day after I pulled it out of the garage after working on the rear suspension. I couldn't get it to idle up without it either backfiring or stalling out. When I first cranked it cold it was fine - even power braked it (not enough to spin the tires but enough to put a load on it).
I let it cool and it cranked and ran fine again.
Cranked it again tonight after work and it's still good.
I did leave the battery off of it for a couple weeks while I was welding on it and I know the computer has a learning curve, but I am starting to think this is more heat related.
Where do I start looking? It has not thrown any codes. I could not tell you my timing and have no reference with the explorer serp on it. We timed it by ear when we first started it and I haven't had issues with it before.
