Rough running, misfiring and rough idle is driving me crazy! It seems to be getting worse. Not sure how long the truck will idle for in the future.
Vacuum reading is 14 inches but timing is OK. About 9 degrees and wavers slightly when I open the throttle.
I have checked the all the vacuum lines I know. Perhaps the camshaft sensor in the distributor? Vacuum leak in the heater flaps? They are sometimes slow to close and bleed hot air when I want cold. No hissing though around the dash.
Thanks
