    87 P30 5.7 TBI Help please

    You are not going to be chasing power you are chasing ground the fuel injectors are controlled by ground from the computer so if your control wire( ground wire for the injectors) is shorted to ground then it will also cause this problem!

    Driveline vibration help

    Well check your pinion bearing normally if it was that bad you would have alot of noise. Put this thing on Jack stands and get it to speed and try to get a visual on it.
