SOURCE: loud whistle on right side

ensure that your exhaust pipes do not have a problem. as you accelerate more explosion comes out the exhuast pipes and if there is a "hole" in it then the whistle will get louder as you accelrate more.

How to check auto chock ?

"chock"? Do you by any chance mean 'choke', as in a fuel enricher for an engine? Or do you mean some mystery vehicle or trailer that 'auto chocks' the wheels?

The Search Query for this is

'make model auto choke'

Such questions are impossible without 'make model (what it is)'. That should be in all questions, first 3 words.

Dies on exceleration

Have you had your fuel pressure tested? Low pressure and/or volume could cause the truck to idle normally, but not be able to take any load. There is a very high failure rate on these fuel pumps.

Loud whistle on right side excelerates as I excelerate. stops at 20-15 miles an hour

ensure that your exhaust pipes do not have a problem. as you accelerate more explosion comes out the exhuast pipes and if there is a "hole" in it then the whistle will get louder as you accelrate more.

Won't accelerate past 40 miles per hour

these jeeps did have a small problem with the tp sensor. i would also have the back pressure of the exhaust checked to see if you have a catalytic converter choked up.
