Just bought my cherokee 4.0 few weeks ago with a noise coming from the top end. Was reading a little and found that people have issues with sludge and u gotta clean a tune so I just started pulling things out and for some stupid reason pulled out the CPS gear. Now the motors misfiring at idle and sometimes while accelerating.

I read numerous posts on retiming it setting to tdc the finger in spark plug hole process and the toothpick. I did all that and it starts but after a few cranks. And then while driving it will be fine. Come to a light and it's shake, not crazy but noticeable. Check engine light on. Codes are P0353, P0352, P1294, P1391



Still have to get it inspected so I'm trying to get this fixed ASAP!

Thanks in advance
