#24 of 27 2002 Avalanche by boggsy1 Sep 13, 2009 (3:47 pm)
My truck has been running "rough", loss of power, sputtering. Check engine light is on intermitten. I had Auto Zone read the code and it was a mass airflow sensor. I bought a new sensor and it seemed fine, the engine light went out. Today (one day later) my truck wont start. I thought I may have gotten a bad sensor so I got another one. I will try it tomorrow. Just wondering if anyone else has experienced this problem. Thanks!
#25 of 27 Avalanche or Toyota Tundra by chris_4325 Oct 24, 2009 (5:13 pm)
I'm looking for a new car/truck/SUV and here is my dilemma: I like Avalanche’s look, but Tundra’s reliability. Currently I have 1999 Ford F-150, and never had any problems with it. I bought it brand new and now it has 140K miles on it. Once a while I need a pick-up truck, and I’d like to enjoy the nice look of it. The bed in a new F-150’s appears much bigger to what I’m used to and I don’t like it. I like the appearance of Chevy Avalanche, but I’ve read that people are having some problems with it. On the other hand Tundra would be more reliable, but it is rather a typical pick-up truck. I might also add that my teenage sons dream of Avalanche. Can you advise me please which car to choose from, or give me some thoughts to start with? Thanks.
