Default injector swap: check engine light?
Swapped out my injectors to some 703's and reset the ecm. Idles beatifully. Awesome throttle responce but once I let off the gas after accelerating it almost dies

Any ideas?

Have you allowed for 50 key cycles? Until then, drive it like a baby. Also, check to make sure you haven't fouled out a plug. #6 (back plug) is usually the culprit if you have.

Thanks for the help. Got home today after 10hrs of meetings and decided to work on the jeep to unwind. Plug came loose during the install. Runs better than ever
