Wondering if this could be a result of a MAF failure. Car stalls out while in gear at 70 mph, is jumpy under acceleration, and check engine light is intermittent, code scan revealed P1545 - Throttle Position Control Malfunction.

Problem happens intermittently, especially in colder weather. Also, occasionally, when stalling, the dashboard lights up like a christmas tree with all the ASR etc lights staying lit.

Thanks for your help,
