Just installed throttle body and found RPMs of engine not responsive when I let off throttle to engage clutch shift Revs dont seem to drop. Also just installed 3.73 gears and Detriot Rocker cams.

We checked our voltage before we started found 127.1 We ended up with 127.7 Would this make that much differance in throttle responce.

That should be fine. Disconnect the battery for a half hour and let the car relearn the fuel trims.

1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park) (automatic transmission) or the neutral position (manual transmission), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.

The vehicle may need to be driven 10 miles (16 km) or more to relearn the idle and fuel trim strategy.

I got a little known tidbit from a Ford ECU guy.

When you want to re-set everything put the key in the “run” position (but do not start) and pull the negative battery cable with the key in that position. He said it is the best way to make sure everything rebuilds from zero.

Make sure when you re-connect the battery cable the key is no longer in the “Run” position.

I used to simply turn the battery off when I parked in the garage (I have a switch that disconnects the battery) because the “learning” part of my ECU doesn’t appreciate my driving style and after a day of driving gets a bit fluffy. The next time I drove the car I turned the battery back on and drove away as normal and the car always ran great. Once I started doing it with the key in the “Run” position it ran better then I ever remember it running before. Works like a charm and I have done it for as little as 10 minutes with the same results.

Makes perfect sense... Will have to give that a try.

Si alguien puede traducir esto, se lo agradecería.

Yo he tenido el mismo problema,, se soluciono simplemente desmontando nuevamente la throttle y volviendola a montar apretando correctamente los tornillos en x, es decir, en vez de 1 2 3 4 en 1 4 2 3. Utilizar el apriete correcto 10nm. Saludos.

Not sure if its right but this is how Bing translated it:

If someone can translate this, would appreciate it.

I have had the same problem, fix simply dismantled once again the throttle and volviendola to mount correctly tightening the screws on x, that is, instead of 1 2 3 4 in 1 4 2 3. Use the tightening correct 10nm. Best regards.

throttle body adjustment

Tried 1.25 but engine wont idle at that. tried 1.27 seems to be working better. We found to always make sure stop is against idle adjustment screw before making adjustment.

That's why Ford should have stuck with cables insted of the drive by wire crap. It doesn't take much to though off the voltage. Have you made sure that your connectors are clean and making good contact. That might not help but sometime that can be overlooked.
