Have it checked for misfire codes,,you got one!!

Need to have scanned for codes. Can get a free read at autozone then post result. Probably a misfire condition or exhaust flow issue.

what I found is the timing chain cassets wear over time and the slack in the timing chain causes the mis fire on cyl 1&2 between 1500 to 2400 rpm at a slight load.

Only problem is there are eight (8) different engine options!!

this would be on 2.3 4 cyl 2007 automatic 4x2 @220,000 mi.

If that is the engine option that the truck in question here has in it (no idea) that may be a possibility!
