3. Start engine and let idle for at least thirty seconds.

4. Disconnect Throttle Position (TP) sensor harness connector (Brown), then reconnect it within five seconds. Wait twenty seconds.

Have rechecked the air hose between MAF and throttle body for vacuum leakages? Try cleaning the MAF as well.
