P1294 (Target Idle Speed Not Reached) Help

I just checked the error code and it read P1294. Is this really bad? I have to drive 250 miles back home tomorrow. Can I put off fixing it until I get home?

You will be fine driving it. The only thing is the idle will not drop down as quick when you let off the gas- usually idles high. I would bet it's the IAC causing it. Cheap and easy fix. 2 torx screws and a plug in that can be accomplished in about 5 minutes.

P1294 (M) Target Idle Not Reached
Target RPM not achieved during drive idle condition. Possible vacuum leak or IAC (AIS) lost steps.

Listening to the jeep, I now hear a "Whistling" noise since I got the P1294 code. Does this mean I have a vacuum leak and probably NOT an IAC problem?
Thanks,
Danny O

You can check for a vacuum leak by having the engine running and spraying carb cleaner at various spots on/around engine, especially intake and vacuum hoses etc. and listening for changes in engine idle. If you spray and the engine revs up a bit you've found where the vacuum leak is at it suck in the carb cleaner.

I ended up adjusting the throttle a bit. It's not recommended, but it worked. Every now and then I get the code when a cold front comes in.

This has happened to me a twice and both times it was the intake manifold gasket! Try spraying carburator cleaner at the gasket if it starts to low idle or die than that's the problem just another thing to think about!

I'm getting the same code and I have no idea what to do.

I put a new IAC valve and TWO new TPS sensors in because it seemed that the first one that I bought was junk, then rewired the crappy wiring that I found behind the TPS so that its really clean now. I also took off the throttle body and cleaned everything... sprayed carb cleaner to look for vacuum leaks and got no change in idle whatsoever so I dont think its a leak.

Right now I have the new TPS disconnected from the throttle but still plugged in and im getting a 6.7% reading on the computer.. shouldnt it be zero if its not actually connected to the throttle? I just put this TPS in - if its reading high, could I somehow have another junk one or is it maybe an ECU problem? Im totally at a loss at this point.

Help a girl out, please!
