So my 98 celica gt has been throwin me this code for about 2 weeks now and its not staying away.
I have cleaned the port on the throttle body, cleaned the vacumm line ports on the throttle body, replaced egr valve, tested the vacumm modulator (item to the left of the egr with a filter in it), and tested the vsv which is a purge solenoid on the lower part of then engine (ecm tell it when to allow vacumm to open egr i did all of this and yet i keep getting the code now my last suspects are either the map sensor or ecm now with the map sensor im sure it would run funny and all if it went bad, but the car runs fine and ecms dont go bad often so can any one help me, im taking any suggestion at this point. |
