326 code

[mclark]

Has any one found a fix for this code. Replaced egr valve and vac line, dpfe sensor, hoses and connector, solenoid. Cleaned the ports and egr tube, what to do next. The car runs great, except when car changes first gear, if I do not accelerate out of first gear the car starts to stumble or sounds like it starts to miss fire, once i accelerate it goes away. Any info will help. EEC have been reset but code returns.

326 is an electrical problem, not a mechanical problem. the code says that the voltage in the dpfe circuit is lower than expected - in other words the supply has a high resistance preventing enough voltage from going to the circuit, or there is a short or partial short in the circuit that drains off more voltage than expected.
