Alright this issue is weird
Over the past couple of weeks, every once in a while when i park the car and shut it off the engine DOES NOT shut off completely. It seems to idle at ~300 rpm but i have no way of telling since the tach is dead when the key is off. I recently replaced the fuel pump since it was due to be replaced (was making loud whining noises and groans on priming) and the problem is worse now (I also have a p0172 code as well as soon as the pump was replaced). The car also idles a bit rough when sitting as well.
If i "turn the car off" the engine seems to "idle" at around 300 rpm and will do so for atleast 2 minutes, i haven't tested any longer but it shows no signs of shutting down. The way I turn the car off is I pull up to a space, leave the car in drive, turn the key off (the engine will turn off due to car being in drive and not moving stalling the engine) and then put it in park.
Stuff I've done:
1) Tested fuel injectors (Did the resistance test with multi meter and listened to them with a screwdriver), all 4 were good.
2) Checked the 2 grounds by the driverside headlight. Both grounds showed resistance meaning they are good. I already did the common problematic ground under the passenger headlight. Going to do more research before I look at other grounds
3) Spark plugs were checked and were good.
Going to clean the throttle body this weekend.
I can post a video of this happening it's a bizarre problem to have in my opinion.
I have a 2007 Jeep Compass with 4x4 and the 2.4L engine. Any help/suggestions is greatly appreciated.
