i have a 95 auto esi.
this car has been sitting for a while from the pervious owner who boosted wrongly.(positive and negative inverted)
and both the ecu and tcu were died.
i replaced both the computer and changed the spark plugs.
the car is running now, but it break down sometime when idling and seldom when the car is running.
i also put a bottle of injector clearer in, but the result is not so obvious.
what is the next thing i should do
should i change the timing belt?

thx @_@
