Hello All!

I went to check my engine codes today, and this is what the auto zone scan came up with:

P0171 - Fuel Trim; Bank 1: System Too Lean
P0102 - Mass Air Flow (MAF) (G70): Signal too Low

I also had P1296, but I just replaced my coolant temperature sensor.

From my reading it looks like cleaning the MAF may help, does anyone else have any suggestions? Does one cleaner work better than the other?

Thanks!

I would go ahead and check/replace vacuum lines first. You can try to clean the MAF but know that they are over sensitive and a simple bump can blow the sensor.

what kind of air filter do you use? Do you use a normal one or an oiled filter?
