Check engine light on. Code p01101(MAF) cHECK ENGINE LIGHT RESETS ON ITS OWN ONCE IN A WHILE. Replaced MAF sensor and air filter. Cleared code with code reader. Same problem. PCV checks ok and can't find any vacuum leaks using carb cleaner. Engine runs fine but after a few drive cycles after resetting code, I'm still getting 2 incompletes on the monitors. Oxygen sensor heater and evap system. Purge solenoid is good and gas level is half tank. wiring connector on MAF sensor also appears to be okay. Any ideas what is causing code intermitantly and incomplete sensors?
