Engine Performance problem
1990 GMC C1500 V8 Four Wheel Drive Automatic 293000 miles
hi there could you help? My truck is a 1990 gmc 4x4 1500 with 2930000 kms on it. This started when I would go through a carwash, now it happens when it rains. So I replaced the sparkplugs, wires, cap and rotor- still does it? If and when I can drive it when it gets hot it runs o.K. And after a couple of days of driving it will be a little better but sometimes when I start it up the idle goes up and down then stalls? And again once its warm it will idle, put in gear runs rough- bad take off? CAN YOU HELP?
