Question about 2000 GMC Jimmy
It seems that when I first start and begin to drive the vehicle, the acceleration is very slow until the engine hits 3000 rpms. Then the vehicle will shift into second gear and begin to pickup speed as normal. This just started happening, and doesn't do it all the time but is happening more often. I don't think it's a transmission problem because I don't have any other shifting problems.
I've done all the usual preventitve maintenance. The vehicle is 4x4 V6 4.3L, has 76,000 miles and I've never experienced any major problems. Any help would be appreciated!
I have the same problem when i start it up it takes a while but then seens to pickup as i continue driving, and doesnt happen until i shut it off and restart again. My mechanic told me that it was not the fuel pump because if that was the problem, it would just break meaning; it would not operate basically when it wants to. It would just work or not no in between. I was thinking maybe it could be the the Master Airflow Sensor but i have to look more into that. If anyone eventually finds a solution comment on this add. Thanks

You could check the fuel pump i recently had some problems with my punp after i replaced it where i would get to 3k rpms and it would sorta shut down and wouldnt go past it untill i let off the pedal
