2014 Jeep Patriot Sport 2.4L ~134,000 miles
Nov 30
Nov 30 - Dec 6

Any help would be most appreciated. Thanks for reading.
Nov 30
- First time seeing the ETC warning light (lightning bolt) which was also accompanied by the traction control light (no check engine light); when first cranked that morning.
Nov 30 - Dec 6
- ETC and TC lights come on when first cranked accompanied by rough idle and the RPMs fluctuating on their own slightly; but all of this goes away after a moment or two.
- Periodically while driving on level ground or downhill, and with no other apparent rhyme or reason, the ETC light would come on first and about 5 seconds later the TC light would come on.
- When slowing to a stop or driving slow (5-10mph), the Jeep would slightly lurch forward and the RPMs would jump up and down a little; this was sometimes accompanied by the ETC and TC lights, but not always.
- Sometimes while sitting in park with the vehicle running, the ETC & TC lights would randomly come on and the RPMs would fluctuate a little, but they would go away on their own eventually.
- Without fail, every time the ETC & TC lights came on while I was driving, I would just have to give it a little gas and they would disappear after about 2 seconds (which is why I feel I never saw the lights while driving uphill).
- I never experienced a blinking ETC light during this time, and I'm not sure if the Jeep went into limp mode because I was typically up to speed when the lights would come on, and as soon as I accelerated they went away.
Dec 6
- Installed new throttle body
- Symptoms became worse immediately upon ignition
- The ETC, TC, check engine, and 4WD warning lights came on, accompanied by a much more pronounced rough idle.
- Put old throttle body back in after cleaning it up a bit (though it didn't look very dirty)
- Reverted to same behavior prior to installing new throttle body (periodic appearance of ETC & TC lights that go away with a little acceleration)
- Check engine light stayed on this time, but it was cleared by a code reader
- Significant improvement - only saw the ETC & TC lights a couple of times during these few days and they seemed to be appearing less frequently as time went on
- I assumed simply cleaning the old throttle body did the trick....but then...
- About 9pm, while going about 15mph and approaching our driveway, all hell broke loose - the same four warning lights that had appeared when we installed the new throttle body came on (ETC, TC, check engine, 4WD), though the ETC light was now blinking and it was clearly in limp mode at this time.
- Decided to drive Jeep to work (30 mins) and see how it behaved.
- Drove normally for about 15 minutes before the flashing ETC, TC, check engine, & 4WD lights returned along with limp mode.
- Pulled over and shut off engine; lights and limp mode gone after restarting (check engine light persists)
- This occurred a total of 3 times during my 30 minute commute this morning.
