'01 GT - Misfire/stauling

[rene9797]

Hi Everyone
I am very new to this forum thing and do not have much knowlege about cars, but I thought I would pick some of your brains. I have an '01 Celica GT /Manual - 46k, with all scheduled maintenances. For the past 2months it has been in and out of my dealers shop with a misfiring & stauling issue. They have replaced the fuel pump/filter, plugs and wires, engine computer, 4 ignition coils and the cam sensor. As of now, the problem has not been fixed. Has anyone heard of this happening or have any insight? Any comments would be greatly appreciated. Thanks
