I recently replaced the complete exhaust from (after) the manifold to the end of the tailpipe. There is still a leak from the last adjoining gasket. I am still getting error messages on my OBD11 scanner. Errors 325;441; 450. Could this indicate a faulty PCM. This in my '97 es 300?
Those codes are Evap system codes check the Evap purge solenoid or vapor pressure valve on the tank ect. I hope this helps. Take care.
