Check engine light after WOT

[Zues]

Has anyone been through this. My check engine light flashes on and the car starts to buck after a hard acceleration. This happens for about 5 seconds.

Thanks for the reply. I just replaced the temp sensor next to the temp sendor. Is this what your referring to. Also maf is good.

hmm. do the rpms jump up and down on there own or dose it buck under throttle? If its does it under throttle it could be fuel related.

Its bucks and stutters after throttle.

O2 sensor is probably bad.

Hold on. WOT means open loop so the O2 sensor isnt even being used right?
