Stalling when stopping and driving struggles to get power also.

do you have any problems starting it or just when its running? double check the basics like plugs, vacuum leaks and airway for blockages, check fuse box for any loose or blown fuses and relays. Compression test, fuel pressure (check injectors, pump and pressure test), check the wiring harness for the ignition system for any breakages or liquid getting into any connectors,  faulty MAF sensor. couple of things to check hopefully they’ll bring something up and you can fix it. bad timing could also cause the car to randomly stall but would have others symptoms too, if you've replaced all those parts though it might be worth checking it just in case.

Check the signal that your new cps is putting off pull the plug wire off your coil rig up a nice ground wire with 10g sold copper wire when it sparks it should be visible and sound something like a little tazer but slower .the issue is with the remanufactured parts the engineer's did do the mic work right some of the newer mopar sensors are off adjust with washers to correct. And remember to reset your ecu and if that doesn't fix it you might be experiencing ground strap issues and that is a esay fix install a big 3 ground kit. Best of
