1997 TJ sputters at idle but dies instantly when I touch the gas

[Zwc32]

Hello,

I have a 97 tj 2.5l 5 speed. It died on me this morning. It will start back, but barely idles sputtering badly, but as soon as I touch gas pedal it dies instantly. I don’t want to start randomly throwing parts at it, I was hoping someone can point me in right direction. Thank you

any codes? I recently had a similar problem in my Ranger and ended up needing to clean some sensors and the throttle body

Check fuel pressure?

Check for vacuum leaks?

Clean the IAC?

Thread 'How to clean your IAC (Idle Air Controller) valve'

Jan 2, 2016

If you're experiencing idle issues on your Jeep Wrangler TJ the most likely culprit (and the first thing you should check) is your IAC (Idle Air Controller). Often times the IAC gets very gunked up causing the Jeep to idle improperly. A simple cleaning is usually all it takes to get it running as good as new.

If you end up needing to replace your IAC valve (they do fail on occasion), you can find the part numbers (and the links to purchase them on Amazon) below:

2005-2006 IAC Valve (Part # 4861552AC)
1997-2004 IAC Valve (Part # 4874373AB)

There is no need at all...
