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! |

Don't know about the Rich/Lean situation because I have not checked it with an analyser...Don't know anyone who has one...But I think that is the problem, Rich/Lean...
I must disconnect the inlet temp sensor to get it to run at all... I agree with the resistor in line with the CHT...But I was under the impression that the Resistor situation was only applicable to the 2.0 motor...I think I have a line on a pot setup and I would like to slave it in to gauge the change in performance... Finished the re-sealing of all vacuum areas last nite and it drives pretty good after 180 degrees...This morning it was better, but still spittin' and sputterin' until I got to work because the 20 minute drive warmed it up... 2-OH! |
