Hi guys, I need your help. I just bought a 2008 wrangler with 45000 miles and thought it would be wise to do a full service. Unfortunately something must have gone wrong somewhere along the line because after the oil was changed (my mechanic initially used Mobil XHP) the car started showing the "change oil" message and refused to rev after which I asked a friend that had same car who advised that I used Mobil 1 so I had my mechanic replace the oil but it's still the same situation. Now am worried and don't know what to do, don't want to go the trial and error route on the car cost that might mess some other thing up. Please help, am freaking out this car cost me a lot.

Try a manual reset for oil light if it still does it then have it scanned for codes. See pic

It seem like the something got bumped off such as an electrical connector, please the check the throttle actuator plug and the crankshaft angle sensor.

Get back to me please,

Best, Ken
