for the TPS, it should be between .96v and .98v. You can adjsut the throttle screw but you should do so, then readjust the TPS to the voltage stated earlier so it knows that is idle and not part throttle.
For the timing, it's just the same as the old cars. It's got a distributor, and you turn it clockwise to advance timing. For exact time setting you want a timing light. It hooks up to the #1 spark plug wire and flashes a light on the harmonic balancer that will light up at the exact time the harmonic balancer passes by a pointer and whatever number the pointer is pointing at, thats what the timing is set at. You have to start the car to do this, pull the spout connector, and it helps to rev the motor a little bit while doing it.
And it is EFI, but it is not Mass Air, it's MAP
