Had throttle Body Replaced, Brand New, And now saying (coded) throttle spring is weak. Why and how do I fix it? I just had the throttle body replaced and mechanic drove it. He said it was good to go. I drove it and stepped on it a little and noticed less power then CEL came in. Took it back to mech. And he coded it saying that it is a weak throttle spring. It is a brand new not refurbed TB. Can the spring be adjusted?

Was this a genuine throttle body fitted or an after market unit, I say this as you do often see after market units that do not work as they should even if they are new.

I believe it was p1260. The throttle feels soft too. Not as responsive even in sport mode.

Diagnostic help
Throttle return spring is too weak.

Checking the wiring
Jiggle the wiring harness at several points and in different directions to detect intermittent breaks and short circuits. Observe the multimeter, diagnostic tool or test lamp during the check.

Proceed to Diagnostic Procedures See: Diagnostic Procedures Diagnostic Procedure

I would return to the installer and have them re check there work
