Well, this weekend, because of the threads dealing with the Racor and what it is supposed to prevent, of course I took my inlet tube off, and took my air box apart to get at the turbo inlet. Well, I put everything back together, put a new filter in the air box and drove around town a bit doing errands. This afternoon, the Check Engine light illuminates. It stays on except when the engine is turned off. The Jeep was running fine. I shut it off after coming home a couple of hours later. After about 30 -40 minutes, I had to go out for some more errands, and I tried starting the engine and it sounded like it was running on two cylinders. I shut it off and restarted it. Got all 6 this time, except I noted the Electronic Throttle Control light was flashing. SO I drove to the in laws place downtown. The light extinguished, but now the remote start will start the engine and it runs for about 17 seconds and shuts off. Tried it 2x in case there was a gremlin fooling around in there somewhere. Did it again. Never before had that happen. Guess the Jeep is going to the dealer tomorrow.
Sorry to hear this. Never read about anything like this that I can remember. Interested to hear what you learn. I'm just kind of learning about these Jeeps as I go. Not a tech by trade. And a pretty novice wrench turner also. I hope it's not a big issue.
so there I was.... OTW to the dealer... when lo and behold the Check Engine light went out. the Electronic Throttle Control warning light had stopped flashing earlier... so WTF? I don't know... everything seems fine now... Even remotely starts and stays running.
A few weeks ago, we had the 'Throttle Control' light flash a few times as well. The manual actually suggest taking it to the dealer for service. They had to replace the unit and now it seems fine. Your dealer can just hook up the scanner and it will know the lights have flashed. They will replace it no charge under warranty.
Hi, don't know if anyone will read this a year after all the other postings, but anyway. I have a 2005, 5.7l Grand Cherokee and the ESP and ETC lights came on. Took it to the garage and, hey, no fault codes. I had no throttle at all. It has happened 3 times on start up. Bit of a bummer. I also have a 3.7l Cherokee that I absolutely love. My husband convinced mt to get it converted to LPG. What a mistake. Don't ever get it done!! Just enjoy the Jeeps as is.
