1.check ecu
since u already tackle down MAF

2. if you have turbo (u didnt mention) might be boost leak

might be your knock sensor or tps had same problem

Check:

Boost leak
throttle isnt stuck
BOV-if you have turbo
Boost controller
Fuel pump/injectors
TPS

If its non of the above might wanna look at possible blown gaskets.
Or check compression.

Ill bump this instead of starting a new thread. I have tried searching, but to no avail. My car (97 240 KA-T enthalpy tune) after warming up (driving 10 min) will just fall flat on its face and will not accel. Unplugging 02 made no difference, by passing the turbo and running N/A the car runs ok. Any ideas or help would be awesome!

Thanks!

Bryan
