    Aldl....which ports are for torque converter lockup??

    Can a switch be connected between the 2 ports on the ALDL and switched on when I'm on the highway, or will it fry something? I replaced my solenoid and the pressure switches and it still won't lockup on the highway. I have checked the brake switch adjustment on the brake pedal too. I'd like...

    87 GN pings while hitting 2 red boost lights

    It was the hose off the waste gate T and the hose going to the passenger valve cover. I'll have to go to the dealers and see if they have the shaped hose, otherwise it's 3/8"OD and 1/4"ID.

    87 GN pings while hitting 2 red boost lights

    Thx, I'll use up the 15 bucks I put in the other day and go back to using 94 but I'll try Petro Canada 94.
