93 xlt 4x4 please help me

[doodypants]

When i start driving it feels like theres no power in it. its like it never shifts or something but it does eventually get up to speed just very slowly even if i floor it. and my abs light is stuck on. Someone told me something about a governor may be stuck and its going to cost me around 600 cash to fix it. please if you have any other suggestions let me know.

lift the wheels off the ground and check to make sure the brakes aren't dragging. The ABS unit in my '91 failed so I by-passed it using a brass fitting from Autozone. Total repair cost was $2.50.

Do a search on your problems. It could be anything from tranny to plugs & wires. You need to get a better idea of your problem. Start elminating things.

Would a bad crank sensor have anything to do with it? and also i think i need whats called a knock sensor because if i put regular gas in it i get loud ping but with premium gas its fine.

A bad crank sensor could cause low power, but it is also often associated with a no-start situation or other misfires. In many/most cases, it would also be associated with a trouble code (CM 211, 212, 214 see BrooklynBay's list of EEC-IV codes in the EEC-IV forum).
I suppose it depends on exactly what the problem turns out to be, but if it's a transmission problem, there isn't very much computer control over the A4LD, so I wouldn't expect a CKP to contribute much to a transmission issue.
Are you certain you have a knock sensor? I didn't think any of the 1st gen 4.0's used a knock sensor. Do you get a KOER 225 if you neglect the "goose" test? Do you get a KOER 225 if you perform a good "goose" test? Regarding the pinging, that's a fairly common issue with the first gen 4.0's. Do a search and you should find a lot of information.
