I know the 160,000 mile injectors are seriously hurting performance, and the pump was rebuilt 30,000 ago, but the shop did a really bad job on it. Lift pump works I'm pretty sure, but don't know how to check it, i can hear an electric fuel pump run when I turn the key forward. Timing chain slack is probably there at this mileage. I turned the IP slightly to the drivers side, with really no results about 1 month ago. The advance piston in the injection pump is not working right, it sticks, sometimes you will get a sudden surge of power and it feels great, then it just dies out and back to normal.
