I have a 95 Ford Ranger 4x4 V6 4.0. The problem is the engine is idle rough. No power from starting til 15 m
I have changed spark plug wires, spark plugs. The manual saids to look for vacuum leaks, I don't find any. cleaned air filter. Could it be the timing gear is worn? Or better yet, give the engine a compression test. Not burning oil, it's got 250,000 miles. Got any suggestions?
