me and the girl went out to eat, drove there and her car fine, no issues what so ever. ate dinner came out, she started it ...very rough idle and rumble. she shut it off and it started right up. rough rumble continued. i told her try shifting into reverse. still did it. and when we were at a low speed coasting it continued. got to full speed 30-40 it was hardly noticeable. starting slowing down to turn, it was back

ses light came on when we were still in park at the restaurant, 30 seconds after the rumble...

what do you guys think? im lost. dont have a code scanner. will have to check autozone tmr but dont know if its driveable

any easy checks first? its up to date on maintenance

 

it smells like bad gas, exhaust mix. and still acceleration is very sluggish. didnt wanna drive it too much.

 

nevermind, got it to the shop. its never had a tune-up. I called it lol...shes at 125k, and i told her at 100k she shouldve had it done. luckily its a 4 bangers, less plugs lol
