Hello,
89,000 miles, 4.3 VortecMy Silverado has been stalling and missing over the past few weeks. I have put new plugs/wires (twice, the plugs were burnt up both times), distributor/rotor (just a few days ago), a fuel filter, and adjusted the timing, yet the problem persists. What else can it be?
Thanks, Jimmy
You might do a fuel pressure check (about 14 PSI from pump and about
9.5 to 10 PSI from regulator) and check TPS and maybe MAPas well. Might check for some water in fuel too.----------------- TheSnoMan.com
Lean mixtures or preignition (spark knock)
