is the Service Engine light on? Does it feel like you still have a misfire?

Light comes on at first then goes away after car warms up. Not sure what the light is yet just started 1 day ago for the light. Misfire gives a shutter to the throttle response, rpm acceleration is smooth just no vehicle acceleration. High rpm low acceleration. Going to get car and check the light now.


No light, vehicle acceleration was slow to 50 then started to decelerate after 7 miles could not keep car abouve 30mph once pulled over car would shutter and act like it wanted to die. (500 or less rpm shutter)
