i got the timing belt done in my toyota avensis 02 d4d. the mechanic is happy that the timing and that is correct with the setup.. since then the car is lacking serious power there is not pep in its step if u get me. i not sure what the cause couls be the sympthons seems like dirty fuel but not sure if this could cause the thing to act like so. is there anything i should check out to see what the problem is. i was thinking of getting some injector cleaner to add with the fuel to clear up the problem of dirty fuel.
