i see that a few people have had this in the past and wondering if anyone has resolved the problem. everything i read about this problem im having the same thing expect my car goes into limp mode and the car will not pass 2000rpm. disable o2 and closed loop also. only happens on decel. if i turn my car off and back on it no longer comes back on. even if i decel. happens only when the car has sat over night and i warm up then drive for 15+ miles.(note the car has been fully warm before driving away) tomorrow im going to log the data and see if im able to catch everything in action.

Do you have a O2 sensor connected to the ecu?

no o2 hooked up to the ecu. the wide band is't hooked up to the ecu ether.

If you hook up something, the problem will be gone.

still had a problem with the mil even though i connected my wideband up to ectune. not sure but disabling closeloop+ve correction (stock) seems to have keep the o2 error/limp mode from coming back. car has been running fine so far for about a week now. will update if it comes back on.
