I know that. I am thinking maybe I didn't tighten something up enough.
My car was stalling, so I took it to a mechanic for a dianosis, they said it was the MAF so I replaced my MAF 3 weeks ago and it ran fine. I did not disconnect the battery to reset the computer, however the check engine light did turn off immediatly. After 2 weeks my check engine light came back on. I took it to autozone and they said the mass airflow sensor was bad. I did not get the codes. Since it was only 2 weeks old I exchanged the MAF and installed a new one in Autozone's parking lot. On the way home my car ran rough, as I got it home it stalled. I took the MAF off and tightened up some bolts and it started fine, but would idle rough. It stalled out a few times but started up right away. It ran fine for a few days then as I was going to work (on a slight incline) the engine lost power. I would slam on the gas and got little power. I went from 35 mph to 10. I was able to get back to the car after work (Thank God for friends who come to the rescue.) My friend tightened the bolt on the clamp that connects the MAF to the hose (air intake?). The car started and I drove it home with no issues.
Could the issue have been I didn't tighten the bolt tight enough or could it be something more?
