Ok, 2001 impala, just bogs down when u try to accelerate takes 2 to 3 minutes to get to 40mph hooked up a diagnostic machine at a parts store. Indicated bad erg valve and secondary fan. Changed the valve and the fan along with a new fuel pump. Again its more like to much fuel as apposed to not enough. A 40 mile trip back and forth took a half tank of fuel. Also they took the car to WalMart and had a battery installed, the idjits there busted a vaccum line; but I found that and repaired it. Where do I go from here i'm pulling my hair out!
have the same problem?
