Help! 95 Blazer Vortec V6 idle problems
My 95 Blazer 4.3 Vortech V6 CPFI (63,000 miles) idles like crap, but runs fine when driving. I have replaced the fuel pump and regulator, Oxygen sensor, Idle Air Control Valve, as well as completed a tune up. The right bank of spark plugs were fouled out, leading me to believe the CPFI is leaking and in need of replacement. But before I dump this kind of money into this CPFI, I would like to know this is the problem. Does anyone have any ideas on this? Help is greatly appreciated.
