the key on ,off trick may work
but be warned the keyone off trick does clear some spark failure codes and will not tell you the extended codes, of the factory DRB tool. so the INNOVA can be a "revelation"

Investment grade TOOLS. if ever there was.

I THINK FUEL INJECTORS ARE CLOGED
If you think they are dirty the easest way to clean them from home run it till it only has a quarter of a tank then go to the parts store and buy 3 can/bottles os SEA FOAM (red & white can) dump in tank and drive it like you stole it.
Engine light on and burning to much gas and
You need to get it to a dealer or other shop that has the diagnostic tools to accuratly diagnose the issue. You will spend more money guesing at parts than you will at getting the test ran. If you get a clear answer from the dealer come back and we can help you with any questions you have about what they said or how to make the repair, but trying to guess at your problem is not the way to go, there are too many things that can be the issue for anyone to give you a correct answer with out a diagnostic check.
Stalls and won't idle
This is a very common problem with pretty much any Chrysler product and 95% of the time it is usually 2 things. First thing to do is of course clean the throttle body and the IAC motor (Idle Air Control) motor. Second thing is a little strange but is most is the time the problem. When working for Chrysler Dodge Jeep for many years I saw the problem on almost a weekly basis and it will seem kinda crazy but it does work. You need to have your battery checked and most likely replaced. That's because there may be a dead cell in it that is causing the ECM and PCM to lose it's memory settings. Which causes the jeep to crank like normal but not idle and go dead. The battery will seem plenty powerful enough but this is normally the fix. Hope it helps. Thanks
