[DML] Took car out on first drive in 1 1/2 years, not without problems, though

["Matt Spittle" <supermatty@xxxxxxx>]

So finally, today I took my DeLorean that I bought in July 2003 out 
for a drive for the first time since September of 2003.  The car 
starts fine, idles fine, revs freely up to 6000 when parked, but when 
I head out onto the road it will drive up to about 3000 RPMs and then 
doesn't want to go any further.  Depressing the accelerator just 
makes it sputter.  It is a 5 speed, and to drive it around, I've been 
just shifting early with it.  Top speed is about 55 mph.  

Here's a list of what I did:
-replaced all engine vacuum hoses with silicone ones, replaced W-pipe 
gaskets and o-rings, replaced injector seals, replaced o-ring on 
mixture assembly, all 3 brass screws are closed
-re-gapped all spark plugs to 0.031", I know this is larger than 
specification, but I also have the MSD Blaster 2 coil, so I thought I 
should be able to space them a little further.  
-Completely cleaned out fuel tank, checked every injector by placing 
them in a bottle and jumping the fuel pump; all seem to spray 
correctly.  
-New distributor cap, new 8mm silicone spark plug wires, new ignition 
coil (MSD Blaster2)
-checked that butterfly valves are opening fully 
-gas is 87 octane, and tank is full 
-pick-up hose assembly in fuel tank was replaced with john hervey's 
pick-up filter, baffle being used is a large tuna can (bill robertson 
style)
-frequency valve is buzzing happily

Is there anything else I can do?  Like I said, the car seems to run 
fine until the engine is under load.  For that reason, it seems like 
a vacuum leak, bad RPM relay, or any type of fuel starvation 
shouldn't be the part of the problem.  
I guess I should also mention that right now the car has no oxygen 
sensor, and the exhaust manifolds are connected to straight pipes.

Where should I begin?

thanks,

Matt
