Ecm data link problem on an 92 oldsmobile 88

SOURCE: engine check light is on

does the car buck on the highway when accelerating under a slight load?
i owned one of these exact cars,3.8 litre.
2 problems. one,the baffles braek in the gas tank,and if you run 1/4 tank or less it will stall in a turn.
mine it was a right turn.
2nd problem,the EGR valve was stuck and it would surge or "buck" on the freeway.
replaced the egr (exhaust gas return)valve and it ran like new.
if the egr valve is code 42,(i do not have the manual in front of me) you have found the problem
check the egr,it can cause the problems you have.

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. Raise and support the vehicle safely.
3. If necessary for access, remove the splash shield.
4. If equipped, unfasten the flywheel inspection cover bolts and remove the cover.
5. Label and detach the electrical connectors from the starter.

1. It may allow more room it you remove the right side cooling fan.
2. Remove the starter-to-engine bolts, then carefully lower the starter from the vehicle.
