[QUOTE="redbullet, post: 437616, member: 19555"] You may have a worn cylinder. Check the compression on each cylinder. Harbor freight has two test kits. I found the slightly more expensive one to work better. Depending on the severity of the results you may be in for a rebuild…or if it is minor try using a quart of Lucas high mileage oil stabilizer with each oil change. My 2.5 has slightly low compression in one of the cylinders and it loves when I put this Lucas engine “honey/molasses” in it. Dang, just re-read your post and it stated you checked compression…now my only suggestion is marvel mystery oil…kidding. How about clogged catalytic converter, vacuum leaks, cracked manifold.
