hello i have a 01 grand cherokee 4.0 it has 200,000 miles on it and 30,000 since the engine was changed the problem that i am having is at speed i am having intermitten stalling and or almost stalling sounds like it runs on only a couple cylinders if i put the trans in nuteral and turn the key off and back onit will fire right back up and run i have already replaced the crank position sencer and the code is still showing crank position sencer and coil pack 1 2 and 3 the crank position sencer that was installed was from the dealer please if you know what to check and or what it could be i would greatly appeciate the help and thank you in advance

 

ok i just instaled a cam position senser that however was not the problem i did find the problem though and it was the ground cable that goes from the motor to the fire wall was in bad condition changed it and that seems to have fixed it for the time being i hope that this helps sombody in the future

 

Thats good to know, thanks
