Friends 95' S-10 2WD Vortec TBI 4.3 The problem is magically overnight it started running like [censored]. Cranks, fires, but seems to run on only4-5 cylinders. So I've checked everything, fixed a few problems on the way but still hasen't fixed it. New plugs, fuel filter, gas, plug wires, coil, air filter, cap/rotor. I can drive it ok if I drag the brakes and keep on the gas. It runs ok with throttle and a load, but not at a idle. Got spark, got fuel and its smooth on the road. Engine code 32 is coming up, EGR system. Need some input, Thanks Guys! Displacement, cubes, and did you say you drive a riceburner???
