I sprayed throttle plate cleaner around the runners and vacuum lines to no prevail. The code comes on now IN GEAR with brake applied. I assume its because the idle drops down so low and it sees low vacuum?

If you brake torque it in gear, the car hesitates, and pops both through the intake and exhaust. Like I said it does this when warm after warmed up. Could this be another OPTI issue?

I unplugged the MAP sensor and it seemed to run better at first but then had the same symptoms.
