hello,,,im hoping for some help with this problem on my 2000 cherokee sport. it started with 1 code on my actron pocket scan,p1391. i replaced the cam/crank sensors. becouse it would stall out after driving a few miles. after replacing both parts went for another drive it didnt stall out but started missing bad,,whole thing was shakin,,shut it down for a few minutes and started an drove fine.(same with above stalling). i replaced plugs and boot caps, it drove alot farther this time but died again,,set for 5 minutes and drove fine. but popped alotta codes,,p303,,p1391,,p0351,,p0352,,p0353,,plus a few others that were on the computer my reader didnt see. any help? PLEASE

0351, 0352, and 0353 are coil rail defects. 1/6, 2/5, 3/4.

When you changed the plugs did you make sure the coil rail connector was securly connected.

Did you clear the codes by disconnecting the battery negative cable for about 5 minutes after changing plugs?

1391 should have been fixed by repalcing the cam and crank sensors.

Look for a new rail in your future.

i didnt replace the plugs myself,,it was sub zero temps. and no garage had a mechanic do it. he is baffled by all theses codes. when i erased codes the first time with my pocket reader,,the next popped as a missfire and erased it with a high end reader, but every time it screws up on me it sits a few minutes and drives fine. after the plugs,, it drove the farthest b4 poppin codes. thats when 1391 came back with the cyl.3 misfire and rail codes. the rail is only $140 from jeep dealer but i wanna be pretty sure thats the couse,,its starting to get very expensive

Did you verify that the coil rail connector pins and pin cavities are not corroded or damaged, and is secure?
