So doing some VOM Tests (proly should have done sooner) I found that the

Throttle Position Switch was not Making Contact @ Either Idle or WOT & Temp Sensor

had No Continuity, Swapped in used T’B’ & Temp2 & Finally got good running,, Not

Perfect but OK enough for now ~ Owner arrived in town & after some driving some

around ABQ that Eve & the following Day, headed North to Colo ~ Got to where He

wanted to be the following day but not without some grief ~ When transitioning to

Slower conditions after longish Hiway Speed stretches the Eng becomes UnHappy &

will stall & then after some period of time will start again & allow more Drive Time ~

I suspect that possibly the Used Temp2 Snsr might not be reading correctly on Hot

End of Scale ~ Any other ideas appreciated ~

        Another Oddity > Coolant Level Warning Light Flashes Constantly with Key On

Even with Connector Jumped & Relay 43 Removed ~ Any ideas on that ~

        Ended up with 

Orig ECU

Used Harness > Orig Bad

Used Dizzy > Orig ?

Used ThrottleBody > Orig TPS Bad

Used Idle Control Relay > Orig Bad

Used Temp2 Snsr > Orig Bad
