Engine Performance problem
1995 Chevy Blazer 6 cyl Four Wheel Drive Automatic 175000 miles
I've replaced the plugs, wires, cap, rotor and distributor. I also cleaned the EGR and the idle air control solenoid. This did help but I still have a hard starting issue (not as bad) and a rough idle. There was AM radio noise but it dissapeared when I replaced the distributor. The plugs all seemed to be burning equally.
