3 check engine codes

P0171 - Bank 1 lean
P0101 - MAF sensor
P0174 - Bank 2 lean

The truck is running fine, what little I drive it. The light has been coming on and off for the past couple months, I finally remembered at the right time to plug in and check codes today. Am I correct in guessing the MAF sensor code could very likely cause the other 2 to trip as well?

yes, any unmetered airflow can cause all 3 codes to appear.

Thanks. Now the trick is to remember at the appropriate time (like when I'm home and awake) to clean the MAF sensor. No worries, I have the special cleaner for it from previous vehicles

If that doesn't get it, look around for a vacuum leak.

Cleaned the MAF and cleared the codes. Drove the truck the past 2 days with no light coming back on. The econo-box Saturn got a couple days break since we were dumped on by the snowstorm and they don't plow the streets, so anything 2wd has a real hard time getting anywhere.

thanks guys
