1994 ford ranger has started bogging down... and losses power whats the problem? on 1994 Ford Ranger

doesnt loss power always but is doing it more often. almost seems like its about to die if going up a hill.

Asked by for the 1994 Ford Ranger
Does it have a rough idle and seem to clear up at higher rpm's? Check the compression in each cylinder. My 2.3 had a chipped valve in the #1 cylinder. It still ran, but the idle was rough and it lacked power. It got worse the more it ran because it caused the plugs to foul.
