Re: so.....i just bought a topaz
if you ran fuel injector cleaner and it magically cleared up, the injectors gota be horrible. id replace the fuel filter to, blow all the fuel out of that line, drain all the fuel out the rail, run alot more fuel injector cleaner like on a perscription for the car.
even think about flushing the tank.
possibly cleaning out, replacing sum injectors.
if you car jerks really bad it could be a sign of weak/broken motor mounts, espically the rear/front transaxle mounts. cheap and easy to replace.
if it suddenly drops to low rpms, make shure all sensors involving the air intake system are pluged in, theres no leaks in the vacume hosing. next up think about replacing the idle air control valve.
last, is the car an automatic and does it feel/happen as a shifting problem?
