I have recently developed a severe hesitation problem. Cyl 1 shows
> compression of 120. Other 3 have 150. If I squirt oil into 1, it
> also shows 150. There has been no change in compression or vacuum
> (18) since before the problem, but the hesitation and missing started
> suddenly as I was
> driving last week. Prior to this, I ran smoothly at all speeds up to
> 85 mph., although the engine had been a little weak, I consume very
> little oil, except at sustained very high speeds,
>
> Now the engine idles nicely, but hesitates under load under any
> driving conditions. I removed the #1 spark plug wire and grounded it
> to the block. Car runs much smoother now on 3 cylinders at all speeds
> than it had been on 4 with one missing..

------------------------------ Look inside your distributor cap for red dust. If you find it , do a google(groups) search for 'red dust'. I think your timing belt has jumped a tooth. Did you ever tell us what kind of car it is, or the mileage ? ? ? 'Curly'
