My 92 gmc jimmy sle 4.3 liter engine keeps dying after driving 7 miles or when engine eats up good.
I had a shop change fuel filter, fuel pump,
and a fuel tree or rail I suppose. It still dies
after a while , before it dies, I give it gas and
it loose power.
Check for a clogged catalytic converter. Do this test at night let vehicle idle for 5-10 minutes then look at the converter if if start s to turn red converter is clogged.
