i have a 1994 chrysler new yorker, i was coming back from target and i felt something interesting i was unable to accelarate over 5-7 miles per hour. everything was fine before its just happened. My check Engine light is not on. So i dont know if it is something to do with a tune up i know it is not my transmission cause my engine is not accelerating at all. So if anyone has any ideas if you could definitly give me something Thank you .
