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
