    If you have linkage from the pedal, look for where it's binding. If it has a TPS, it may need cleaning or replacing.

    I was having problems with the throttle lever I just got it welded could that be the problem? A mechanic said it’s probably the fuel pump.

    It depends on where it's welded. Work it from the engine side, see if you notice it hanging up.

    Fuel inj. pump does that when they start to go bad later on it will red line the motor, they are cheap to get a rebuild one?

    L10 would be a PT pump. Sounds like fuel pump is sucking air.
