PLEASE CAN YOU HELP. JUST HAD A TIMING BELT FITTED TO OUR CELICA.

(BY A DECENT GARAGE) AND NOW THE ENGINE IS KNOCKING . . LIKE "PINKING" . A FRIEND OF MINE HAD HIS H REG GT4 DONE BY A DIFFERENT GARAGE AND HIS IS THE SAME! ANY IDEAS ???????

THANKS

Pinking sounds like someone shaking a bag of marbles. You only normally hear it when you accelerate and its most noticeable when the engine is labouring. Does that describe whats happening?? Its caused by the ignition timing being a little over advanced. You have two options really, 1 try a higher octane fuel (optimax etc) if you dont already use it that is and 2 adjust the ignition timing.
