What happened today :

For the past couple of weeks, I had my car parked until I took it out this morning, it was driving fine, I had my foot on the gas paddle going at around 60km , suddenly the car stumbled like it wanted to quit on me again. So I pressed harder on the gas, it was OK for awhile, then I had to go uphill, did the same thing. Then the check engine light came on. So when I got home, plugged in the OBD II, got the code P0102, and the previous code P0201 which I had before was gone. The car felt like it wasn't getting enough gas, fuel pump not pumping enough fuel. But the code is for Mass Air Flow, Try deleting the code with the OBD II, but it came back after 30mins, and same thing happened again. What is going on, new cide , old code no longer exist. What is going on, what is the problem with my car..........????

 

Checked out the MAF sensors and they are working properly, but still getting the same OBD II code, what else could it be, ehat should I check next..????
