potentiometer please Help
Please Help guys, 1988 300 ce, When I force the first gear start the car doesn't accelerate till 2500 rpm then it goes with gusto, If I let the car start in second gear from a dead stop, it is lifeless till 2500 rpm then takes off again.
If I push the gas slowly down from a dead stop it slowly accelerates till the pedal hits the 3/4 mark then the car takes off with the same gusto as a down shift from second to first, even though it's in second gear start, If I force the first gear start from dead stop, again the car feels week till I hit the 3/4 mark with the gas pedal then it takes off again, The last part is the gas pedal is way more linear when the car is cold, there is no snap in acceleration @ the 3/4 mark. If I tap the gas from a dead stop the car will leap forward when cold. This problem with dead gas pedal only occurs when the car is @ operating temperature. I was thinking this could be the airflow sensor (potentiometer) ???? is what I was kinda looking at as the problem. The car idles great and doesn't misfire, Thanks in advance for any advice you can offer.
