hi i have a wrench light on my ford escape and i changed the throttle body and did not solve the problem and i calibrated it.. it can idle all day and rev it up but sonn as u move the vehicle forward the light will come on. any suggestions anyone?

 

Have you had a chance to have your vehicle checked for any codes in the vehicle's computer?
Might help provide some direction.

 

Some systems have what is referred to as a bias voltage sent to them to run a quick check on system integrity before the vehicle even moves.
It would appear your vehicle has detected a fault in the system that is causing the wrench lite to illuminate. It would be a good idea to either check or have it checked for possibly something other than a questionable throttle body.

 

i have agood snap on scanner and i scanned it a few times but no codes show up at all weird.

 

Can you post the data stream readings , (RPM, coolant temp, fuel trim,TPS, all the data it can provide at idle and at 2500 RPM ?
We may be able to spot a problem if able to see that info.

 

 

 

thats all at idle if that helps now i will send u at around 2500 rpm

 

 

hope this helps short term fuel trim does not seem right
