I finally got my motor in the car. I have it started and no more leaks. I am now having a problem with the engine dying if you open the throttle too quickly or if I shift it into gear. I am guessing that I am having a fuel issue?
I don't have a vacuum pump. So testing the vacuum with the volt meter is difficult
I did break out my volt meter and do as much as I could with what I had. Here is what I found out.
Pin A (Which is the red wire) is exactly 5.01 volts dc. (this looks good) Pin C (which is a black wire) is a ground (also good 12v to battery positive)
On to pin B (Green wire) which is the one that changes in response to vacuum.
With the key to the run position but the engine off. Pin B is putting out 1.25volts dc. From what I am reading, It should read close to 5 volts at this point.
When I start the engine and check pin B, I get some weird behavior.
The voltage at pin B likes to hang around 3.5 volts with the engine spinning about 1500 rpms. (It was cold when I started my test combined with this problem I am having)
When I open the throttle... It never drops bellow 3.5 volts; however, I did see it jump to 4.5 volts sporadically. Theoretically, as vacuum increases, so should resistance at pin B?
Do you think I have a bad map sensor? I think I do but just want confirmation before I go throw another 40 bucks at the problem.
Some information. I deleted my EGR and have a reprogrammed PROM installed from phonedawgs to delete the solenoid and lower stock idle. The engine is timed 10deg advanced. I have not had this new motor on the road yet.
