I have a 2003 Tahoe with a 5.3 with 80,000 on it and we just drove up the Alaska Highway and when we got to AK the "check engine" light came on. So I had it scanned and the code came back as "fuel difficency" on banks 1&2. I cleaned the mass air flow sensor but it is still missing at idle. Once I accelerate it runs fine! Any ideas? Thanks!
have the same problem?
