Don't know
I was driving on the freeway, I dropped my speed from 70mph to 30mph due to traffic. I
tried stepping on the gas and it wouldn't pick up speed over 45mph. Transmission fluid is
at full, oil in my engine is full and coolant was full. Didn't over heat but my check engine
light turned on. The truck never gave me signs that it needed some sort of mechanical
work it ran perfectly. I want to know what could've caused this problem. My truck is a
1997 DODGE RAM 1500 5.9 Automatic transmission
