I have already sent this to Brad Anders, but I decided I would like your opinion as well...
Going thru hell with 1973 - 1.7 D-Jet running awful from 0 to 180 degrees (oil temp)...Bucks, snorts, spits, unstable RPM, all before 180...Runs OK (not great but OK), after 180... Newly rebuilt MPS (Bleyseng), switched ECU's with known good unit, no help... Newly purchased from Pelican, Head Temp Sensor shows 3.16 OHMS...Old HTS shows 3.65 OHMS... Currently re-sealing all intake runners, plenum, TB, etc. looking for vacuum leaks...While I had the Thermo-Time sensor off the block, I checked it with an OHM meter both hot and garage temp (approx. 75 degrees) and got no reading at all...Indicating to me that the unit is open... As I read the wirnig diagram, all the Thermo-Time switch does is complete the ground for the Cold Start valve and therefore would not effect starts in 70 degree weather... Is that your intrepretation of the Thermo Switch...If so, I can eliminate that as a possible source of my trouble... Thanks, 2-OH! |
