Reading that Map deal makes me want to noodle with mine. My high mileage engine has lower vacuum, wonder if I could get an mpg or two if I alter it's feed....

HE HAS AN OBD SYSTEM. HIS REFERENCES TO USING THE 02 SENSOR DO NOT APPLY TO RENIX. FUEL PRESSURE AND INJECTORS AS WELL. I do think the map is the same though.

Increasing the input voltage increases the output voltage and decreasing the input reduces the output voltage.

Heck maybe I'll be the "Guenna pig", again and just put a resistor in my Map feed too. (the 225 ohm in place of my Iat at least didn't hurt, and seemed to help MPG) Anyone else pushen 300K is welcome to try with me!

Your connector at the map still have the clip or has it broken off?

Look at the inside of the connector. I'm wondering if there is a pin pushed back in, not clamping tight or the like.

All the pins are good nice and straight all stick out about the same. Could a bad ground somewhere affect just the Map sensor?
