Re: 2003 TJ Stalls after ECM replacement
Having the right ECM is not all of the picture, you have to have the right program and limp home resistors too. Iím running a 305 TPI out of a Pontiac Firebird. The same ECM is also used for an S10 with the 4 popper but with a different memcal.
In your case, itís probably flash memory rather than a memcal chip. Unless the ECM came out of the same vehicle with the same engine and accessories, you may have to have it flashed with the proper program.
