Fuse Box 97 F150

This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and so not compensated for and can lean the engine out and can furthermore permit the engine to rev taking place later than not desired causing scratchy running. As its a mechanical oddity it tends not to twist on the anomaly fresh and you can sometimes hear a hissing noise past the engine running.

.

I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. like I unplug it and direct the motor, the car runs gruff and at 850ish. I can isolated guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much manage in the exchange of rpm though? I think it isolated adjusts it vis--vis 1k..

Hello the TPS does have an effect on switching the car into idle mode suitably I'd recommend to make clear the throttle plate is 100% closed and not slightly stuck following carbon. and later become accustomed the TPS appropriately that the IDL pin is continuous to the E2 attach similar to the throttle is closed, and admission circuit bearing in mind the throttle is just cracked. Don't badly affect more or less any voltages, the IDL entry is the really important one.
