what havent i fixed in my gmc sierra 1500 4x4?

[Derek Snowfall]

I bought a 97 gmc sierra 5.0 4X4

I feel like my truck is driving so slow.i think somethings wrong with it still because i drive 2 differnt types of trucks for work. i will be pushing down the gas and my speed will decrease if i push the gas down to fast. if i wanted to do a burnout(which i dont my tires suck) i couldnt because i would have to release the gas quickly to let it catch up. its some sort of delay and a unusual idle. im really hoping you can come up with an answer cause i have put so much work/money/effort into it. And everyones telling me that the only reason it drives like crap is because its crap with wheels. and im starting to beleive please help!!

ive replaced a drive shaft(hole), catatilic converter(was dead),fuel injectors,gas sender (dead),gas tank(hole),spark plugs,sparkplug wires,radiator(hole),fan belt,belt tensioner,adjusted distributor cap,all brakes,power steering hose(hole)

after all the parts i put into it its still has some problem with it. after Replacing my gas sender it felt like it made a good difference but not the difference i was looking for.

Seperate questoin: When its in 4x4 it runs fine STRAIGHT but if i turn at all i get this weird rubbing like noise. and thats turning both left right and backwards. if i turn less slightly the noise reduces.Also i my 2wheel drive Low doesnt work. i THINK it blinks then turns off not sure. I can live without 4x4 for poverty sake but i dont wanna take my trucks balls away. can u help us?

Clean or replace your MAF and MAP sensor. You also may want to treat your Sierra with http://www.seafoamsales.com/. This will clean out any carbon in your engine that is robbing from your engine's performance.

As for your 4wd issues, sounds like your front axle actuator may be sticking and will need to be replaced with the updated one that is out now. The old actuator is thermal activated and are known to stick in the winter time, the new one is not and work in any temperature throughout the year.

Good luck and let me know if you need more information on the new front actuator and don't forget to check the front differential fluid if not replace it.
