I've had this to 2 different shops in the past week & still nothing solved(had it at a repair & a transmission shop). This monday its going to the dealer. I'm to the point that I'm fed up with this gmc junk box. Even though it's a gm 4cylinder piece of junk, it should not run like a 3cyl geo. It struggles to take-off & it defintely struggles to take-off if it has to slow down to a crawl then take off again. It deffinitely boggs down (holds back) when ever you give it gas or take-off. The cat, transmission, fuel system, map sensor has all been checked, tps & fuel filter has been changed. Engine cylinder head has been
re-done when I got it(I've owned this truck since june2011). My old 98 dodge neon had way more balls than this gmc/chevy junk box & it had 225000miles on it. Like I said, its going to the dealer monday, and if they can't figure it out, its going up for sale or the junk yard!
have the same problem?
