99 Pontiac HELP!

My car does not accelerate as fast as it should. The throttle has to hit 4RPM and then the car accelerates into the next gear. When I go down hill. The car picks up power but the meters on my dash all shut down and hit zero like car is turned off. There is also no engine light turned on, or overheating. Help me out, what might this be...

Welcome to AF!

You mean it doesnt shift untill 4k rpms??

If that's the case then Id take it to a trany shop, that could be a serious problem(s).

I would also have the trany fluid level checked !
