iac

Hello all, So I had a couple of codes pop up a month or so ago. Misfire on cylinder 5, a couple of O2 sensors and a failure to reach idle code. I replaced spark plugs, O2 sensors, and things were good for a bit. Haven't thrown a code since. But I am having this weird revv problem. It runs fine...

My 02 TJ has been idling very poorly recently, I have a new throttle body (different thing), new TPS, and just recently cleaned my IAC with throttle cleaner and it did not help. My spark plugs all look fine and the jeep runs fantastic when it's driving and when it's up to speed it just idles...

A few weeks before, I drove my TJ thru a river, it wasnt that deep, (almost tire height) and when I come back from the trail, the idle was really high (2,000) and driving in 2 gear when I press the gas, it feels jerky, the bad ones, they make you jump in the seat. Back in the garage, I get a...

I recently rebuilt the engine in my 98 TJ with the 4.0. New pistons, lifters, push rods, gaskets. My buddy cut the exhaust off literally right after the manifold and before the Cat. I’m faced with an idle problem. When it warms up it idles around 1500-1700 sitting, and can get up to 2000 with...

Got everything up and running finally after a long winter. Went for a drive in the morning and everything was running smoothly. Then in the afternoon went for a drive and within 1 mile started stalling (I have a 2002 Wrangler X 6cyl automatic). I was able to shut down and restart, but kept...

I can't seem to win with my TJ. Just fixed a few issues and now I'm throwing a p1604 code. This is a communication issue apparently with the computer. I just completely removed and cleaned my throttle body and IAC so I'm thinking something during that processes may have caused this problem. The...

I've got a 97 2.5. I was getting a p1294 about not reaching low idle rpms. Read some threads that said either the IAC is stuck/needs to be replaced or I have a vacuum leak. I sprayed some throttle body cleaner through it while it was running, giving it some gas so it wouldn't die and some...

Hi all. Here's the story: I've only had my 2004 TJ for about a week or so. I purchased it used from a dealer, and overall it runs well. Drove it this morning, all was good. Several days ago, she did something weird: She whistled. Not a small whistle, oh no, but a large all out steam kettle...

Ok so on top of the key switch problem, There is a random stalling while trying to go through a drive through. Replaced plugs and still does it. Cleaned out throttle body. Still persists. Ordered tps and map sensor. Wrong ones came in. Few months ago I replaced the muffler and catalytic...

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...
