1999 chevy lumina multiple codes Sign In

I have a '99 Lumina (car) with a 3.1L and about 80,000 miles on it. I just purchased it so I have no history on it. I am an ex-mechanic of 15 years and im now disabled due to brain cancer among many other health problems so I no longer have access to Mitchell on demand or All data. Im getting a slight hesitation when I start to accelerate - very slight - and I keep getting the codes P0102 - MAF or VAF A circuit low input, P0135 - 02 sensor heater malfunction bank 1 sensor 1, and P0443 EVAP emission control system purge valve c fault. Other then that, the car runs great! Past experience is leading me to think its a bad computer since they may all share a ground or 5 volt reference signal from it but ive never been one to guess so if any of you could help me link these problems or just help me in any way I would really appreciate it! Thanks guys and what you do for people here is an awesome thing! Keep it up! Everyone needs people like you.

Well nevermind - I found it - someone for some reason removed the 15 amp ecm fuse that controls those 3 things. I put one in and the codes are gone and no more hesitation! Its official - Ive seen it all! Always start with the basics! Thanks guys!
