Hi All
I have a 1992 se 1500
about two weeks ago on start up I noticed (heard) a misfire after the engine warmed up the misfire disappear to my relief
Well it has become progressively worse
I have replaced the spark plugs ( it actually sounds worse)I have checked the spark on each plug and they all seem to be operating Stumped!
I need some advice on what the next step should be
Any assistance will be much appreciated

Check the petcock.
More than likely the diaphragm has a small hole in it near the bottom.
If it does, give thanks to the ethanol devil.
