I have a 2003 tahoe that I never even questioned if it was flex fuel. Today I found the original window sticker that says it is flex fuel. Does that mean it will use e85. Also, if so how does that effect my performance.
Really odd as the temperature dropped the last few days, the idle has been okay, but now my info center says battery not charging. What the hell? Truck has run fine till now that the weather has dropped
In Texas and the last couple of times the weather has been lower than 50 degrees in the morning my girl has had a rough idle. Just at idle, she runs just fine as I drive and after the engine warms up, she stops having issues. 5.3 2003 tahoe.
Just did my 5204 yesterday and really like it for the price I paid. I also did the smart Start which was a simple plug. RS with alarm and security. Clifford is essentially the same system. Both are manufactured by the same company.
