I have replaced the maf sensor and the camshaft positioning sensor but my car still stalls and it can be at any speed, the scan the repair shop did turned up the two codes for the sensors I replaced and, another for the quad driver module. If I replace the ECM would this possibly fix my problem or is the quad driver module one of the chips that has to be put into the new ECM?

Hi clydels,

Thank you for the donation.

The quad drivers are integral part of the ECM and if the ECM is replaced, there is nothing that you need to do.

Fronm the description, the possible cause could be a failing ignition switch cutting power supply to the ECM and engine components. when this hapopens, it could cause the trouble codes to be registered.
