Strange problem

I tried to start my Jeep this morning, and when i turned the key, it just kept trying to turn over. I gave it some gas and it started right away. As long as I kept the gas pushed down the engine would stay running. As soon as I left off the gas, the engine dies.

The battery meter shows that the battery has power when its running.


Any thoughts?

Check the Dash for codes.
If you're sure it's not tuneup related check out the TPS with a meter.

I replaced the TPS about 2 months ago. New plugs and cables within the last 4-5 and the air filter was recharged not too long ago. I dont have a code checker and I cant get it to auto zone in its current condition.

If you turn the key from the off position to the run position 3 times and leave it in the run position without starting the engine, the check engine light will flash codes and the odometer will display them. It will start off with a #12 and end with a #55.
The codes are called MIL codes.

You can also clean out the IAC valve.

I should mention that it does have a remote start, which I use pretty frequently without any issues. I tried the remote start today and after it didnt start, I then tried the key.

You can go though ZeeJay's 12 point check that usually covers 90% of not start and stall issues....

FIXED!! yay! Im not going to pretend to fully understand how this all happened, but what I think happened is this... The remote starter didnt fully start the Jeep and was stuck in some kind of "limbo state" as far as startup-procedures go. I tried starting it a few more times and eventually just tried to keep the RPMs around 2000 to 2500 or so for about 20 seconds before I was just going to let it die. Well it didnt die, it kept running! Something must have cancelled out the remote start portion, or I could just be blowin smoke outta my butt, I dont know, lol. Either way its fixed now, and I appreciate all the help and ideas you had, thanks a ton!

X2, my 98ZJ did the exact same thing a few weeks ago. The Jeep started hard this morning, as in the starter motor was spinning pretty slow. The battery had 12 volts, and no parasitic draw on it. Took the battery in, and it tested bad. These Jeeps are so bizarre when it comes to a batteries starting to go bad. I am thankful it happened now, and not when it is below zero out.
