check engine light on PO443
I have a 96 Bronco with a 351 in it. The checkengine light is on and it has a trouble code of PO443 also the Overdrive light flashes and the engine seems to surge at 1200-1500 RPMS. The sirge quits if I plug the egr. Anybody have any Ideas of what to check? I have checked the VMV and it has the correct ohms resistance.
