sluggish supra

[Riddick]

sounds like fuel injector clogged or sticking, bare in mind that the timeing is correct? have you had it scoped to be sure? another thing is spray the intake with brake cleaner well its running to see if you have a vacum leak, sometimes you cant hear it but its there, wireds? cap? rotor? look at all your ignision stuff make sure its all good, not half ass stuff, i got my car with 3 differant types of wires on it, pull the wires as the cars running make sure there all firing, do the basic stuff, look for compresion, look at the fuel pressues, you may have a fuel pump going south, make sure the pump holds pressue, hook up a gage and see if it drops after you turn the key off? if it dose that means fuels bleading back into the tank or into the engine threw a stuck injector.
