I got a renix 90 cherokee 4.0 automatic. It started cuttin out at first. so i put in a can off sea foam to help clean injectors. Ran great for about three or four weeks. Back to cuttin out almost dyin, and occasional surge. Put another can sea foam, no luck this time. So do I need to at very least clean inj, or possibly replace. Any advice dont wanna replace alot of sensor and what not if I dont need to. On a bugdet.

 

I have the same year and model as yours. I had this same problem a month ago. You need a new tps, but make sure you get yours at the dealership. Afrer that you have to adjust that tps with an ohmmeter. Good luck with that!

 

also check your vacuums, it may have a leak. get a nice cigar and blow smoke in the tube and see where it's coming from.

 

cool thanks for info
