1989 4.3l problem
I have a 1989 s10 blazer 4x4. that has just under 200,000 miles on it.
the problem is under load or heavy acceleration it will have a engine pop. or stutter. it dont backfire. it just misses i guess is the best way to describe it. it has started doing it worse in the last couple weeks. and when it does misfire it will sometime be a single pop. or multiple pops in a row. it losses all power when it does it also. what will cause this.
