Hey so i started my car this afternoon. All was normal untill i put it in reverse and the check engine light came on i dont have a code for it havent moved it since the light came on. the oil temp gauge isnt reading anything and the trans temp seems to be running on the low side (67 degrees) but its also about 55 degrees out side to day. the trans ran a little rough this morning when i ran it but no light was on then so i just took it slow and steady, and she eventually ran pretty smoothly the rest of the trip untill just now the light came on engine sounds normal just got the oil changed and tires replaced and am afraid small town mechanic screwed me over and did something to the car so i would have to go back over and over again. im new to lerarning cars and am very anxious to mess with anything so any info you guys can give or better questions to ask would be great!
