to precede.... i have an idle issue where the car either has VERY low idle (like 200, or 100) or no idle at all (tach won't even move). also, once i drive the car for a few minutes, whenever i have to go back into first, it just dies.. does not return to idle..
with that said, i've been directed to check the TPS or Throttle valve switch.. finally found the switch, and using the Pelican tech article ive gotten to the point where i connect common to common (middle prong) and positive to "idle" prong. ..and... shouldn't it give me a reading?? i have it set to audible (the ohm meter) and i hear nothing once the two connections are made.. i even tried either side of the common prong to make sure it was on the right one... does this mean dead TPS? i know they're NLA and i don't really want to fork out the $$ to fix it as the car is for sale.. is there a way to keep my idle normal and still keep it drivable? dying at every stop sign or intersection takes all the fun out of 914 ownership as you can imagine.. |

thanks rand, makes sense.. so i guess when it dies it 3rd it is to be expected
Jim, i will (ughh) disassemble the thing again tonight and check the actual board inside. I wasnt getting a reading on the ohm meter when testing the pins so i really didnt know how to rotate it "until it reached 0" because it stayed at 0... so that is why i just set it in the middle, being the middle of the grooves.. not skewed to one side or the other. i will also double check vacuum leaks again (best way to do this?) |
