Alright, I know I have posted this 100 times, but im hoping for some new eyes and fresh ideas on this…
I did a 2.9 to 4.0 swap into my 87 ranger
The Ranger is a manual, the donor (a 93 expo) was an auto.
I got the right ECM (one for a 93 manual) everything is hooked up, we have tested all of the sensors, they are all active.
How important is it to have the voltage directly on to what the book says? for example, if you are supposed to have 5 volts running to your TPS and you have 4.6 or similar readings like that…good or bad?
Vacuum tests show that I have good pressure, 20psi with NO movement in the needle, rock solid.
Ive got GREAT compression on all cylinders.
But the thing idles like a son of a gun and runs rich, and when you drive it the idle gets higher and higher and higher…if you turn the engine off and then try to restart it, it won't start right away, Im thinking its flooding when idling, so I have have to put the pedal to the metal and clear out the cylinders.
We are so close to getting this thing running cherry, but we just can't figure out the last step. It's somewhere in the wiring, I am 99% certain on that.
Im using the ranger truck harness and splicing it to the expo engine harness.
