Anyone have the specs on the resistor that is used on the 74, 2.0 head temp sensor? I have a lean condition and need the sensor....how many ohms?

Spoke with another friend of mine...factory trained wrench from back in the "day"....suggested that the MPS adjustment would be better. Not that I'm, a D-Jet whizz......far from it. I mostly did carbs and cams when confronted with a T1 or 4 motor, more power, grunt, grunt, etc. Stock always equaled "loser" in my book.....things change, right? (IMG:style_emoticons/default/dry.gif)

BUT, I DO remember that futzing with the MPS by taking off the epoxy on the back and adjusting it was always the sign of a "boogered up" system.

If it had a fire, I would suspect all the sensors.
The MPS could be leaking, or it could have gotten to hot inside and futz up something.
The ECU could be the same situation.

Krusty is the man...make him figure it out,...or are you being a CSOB...
One thing to test, if he has the Bosch FI tester, it checks every sensor, and validates all the wiring and proper settings of each sensor.

The tests probably would take no more than an hour or two and it also checks the ECU...so its probably a good way to start ruling out the ECU and faulty sensors.
It does check the electrical functions on the MPS...not the vacuum...but the vacuum is what you change when you turn the screws...the elec needs to work for that to have any affect.
