Just bought 94 SLS with 65,000 miles.
At WOT from a stop, there was some serious surging as the motor went through the gears. Two bottles of Chevron Techron later, and WOT is completely different: Smooth power through the gears up to 100 mph.
Cruising at 45-75 mph, I still feel a bit of surging whenever going up an encline. 600 mile highway trip and a very slight surge is still there at the speed limit. (about 24 mpg average for the 600 miles, same as my TTA ).
Any peculiarities I should know about as I chase this symptom? I'm thinking I'll inspect and replace plugs and wires, fuel filter, air filter as needed. Anything specific to this Northstar engine I should know?
Its OBDII, will need an upgrade to hook turbolink up and check things.
TIA
