Engine Mechanical problem
1994 Ford Ranger 6 cyl Two Wheel Drive Automatic 262000 miles
After a long dedicated 14 years, thhr ranger is beginning to act up. Have replaced fuel pump, fuel filter, spark plugs wires etc. But the engine seems to be missing firing on a cylinder when idling. When under power, it seems that the truck is going to buckle over and shudders very badly. The fuel pressure is good @45psi. The transmission has about 160000 on it. It was running ok till I decided to do some PM on it and has never been like before. Every mechanic has pointed in every different direction. The truck passed emissions with flying colors two weeks ago when the problem was intermittent. Now it is continuous. Compression in cylinder 3 is 75psi(as per the repair shop). What should I do next and what is the problem?
Thanks for your help.
