AHA..
OK,
TPS is throttle position switch.
First, lets go through what you have done.
The dwell needs to be set perfectly on this motor, not close enough.
The timing needs to be set while at 3500 rpms.
If and only if that is perfect will anything else make a real difference.
The TPS.
Take off the air cleaner assembly.
Now you are looking at the throttle body.
On one side the throttle cable hooks up.
On the other side is the TPS.
It has two screws, one on either side that you just loosen, dont take them out...and you can rotate the TPS a little bit in each direction.
Once you think you have it right, turn key on, be quiet.
Get you head inside the engine compartment.
Be quiet
slowly turn the throttle while you listen for very small clicks of the injectors. Count the click..I cant remember...but I think 21 is the magic number you are listening for.
Its important to have a click as soon as you move it...and be able to go all the way through the range to WOT and have all the clicks...
Look at the pelican parts web site, there should be a technical article...
Or go to Brad Anders site on the Rennlist (search google for brad anders and djet) he talks all about djet and how to tune it.
Its well worth the time to read his site.

Rich,
Thanks. I didn't have this problem with my old motor. Can a new motor cause this type of problem? I am using a dietributor off a 75 2.0. Might using the wrong distributor cause my problem? I got to go now . I'll look in tomorrow morning.
