After i have been driving my car hard or for a while it seems to get a miss. I have a loss of horsepower between 2000 and 3000 rpm and when i am in overdrive and i hit the throttle down as far as i can without downsifting there is a jerk or stumble about a second apart. I was wondering if this is a miss and what can i do to fix it. Ignition? vacuum hose? injector? i don't know.

 

well when overdrive is on you won't get as much power as you will when it is off, thats all i can tell you, I don't know if you are feeling that as one of your power losses. The car will jerk when your messing around with your overdrive while driving.
