I can seem to get my 914 to not run Rich. I have checked Injector spray paterns, replaced cap,rotor, points, condensor,plugs, plug wires. and belive that my vacuum routing is correct. I question the integrety of the MPS. if i remove the vacuum hose that runs to it and clamp it off i get no change at all in performance. I was told by a co-worker that i should drill out the riviots and check to see if it is gummed up. I just removed it and am getting ready to take it apart, when out of curiousity I ohm checked the teminals and this is what i got : pin 8 - pin 10 350 ohms, pin 7 - pin 15 90 ohms. is this normal? does anyone know of any way to check the MPS. Or could any one do a quick ohm check on theese terminals to let me know if that is a correct reading? any help would be greatly apreciated.
