Car was fine and then it wouldn't stay running one morning. Disconnected MAF to let car run speed density mode and it ran. replace MAF and no further problems.

Reluctant to start but turns over great, stalls intermittently, idles higher RPM than normal and surges when accelerating. Pulled the MAF sensor connection and everything evened out. Planning to replace very soon......

Stalls Intermittently, as if the key were taken out of the Ignition. No Consistent Condition leading to stall.
