I think I already know the answer, but want to run it by the board and all it's collective wisdom.
My son called me this AM from inside his pickup in downtown New Orleans. (It was 30 deg. F outside at the time.) I didn't get the greatest of details from
him but I think I got the gist:
-Apparently his gas pedal would not come back up after he started the truck, and the throttle was fully open by the revving he described.
-He also mentioned the cable was slack when he manually lifted up the pedal with his hand. (is this possible?)
-I'm not clear on how long he let the engine run at such high RPMs, but I think he may have started and restarted it a few times.
Anyway, while on the phone with him, he said it "fixed itself" and all was normal now. I stayed on the phone with him while he was driving to work and all
My guess, and hope, is that the throttle linkage(s) just need some oiling and that the cold weather made things "sticky" for a bit. I would like to address
this problem so it doesn't happen again; or in a more dangerous circumstance.
I'm going to advise him to put a little engine oil on all the moving parts he sees at the throttle linkage, including any exposed accelerator cable parts, unless
you folks give me reason to think otherwise.
Since I'm inexperienced in most things mechanical, your insights are of great value concerning all things Isuzu.
