Changed spark plug
Check engine light is blinking. On and off. No passing speed. Vehicle is heavy
Rough idle and hesitation. Cleaned PCV and found a crack in the elbow that attaches to the trottle body. New hose and problem gone.
changing spark plugs - the old ones have over 100K on them
Code cylinder 8 & 4 misfire. Changed coil & spark plug on 8 & 4. Then code cylinder 7 * 3...changed...then code cylander 1...so changed all. Then code for crank shaft sensor...changed it. Now code for MAF Sensor.
