Spykee 0 Posted November 19, 2003 hi, i take it you have a G-60 then?? what year? when was it last serviced? mine is doing the same at the moment but i am guessing that its just in need of a service cos its been garaged for a bit! check the points and the distributor is ok if not clean it all up etc... and then see if you get the problem? don't know if its what you are looking for but its worth a try! :wink: Quote Share this post Link to post Share on other sites
W3RKD 0 Posted November 19, 2003 to check if the co pot is working take it out of the top intercooler pipe and on the bench prise the blue bung out and put a multi meter across the two outer pins, this should give a reading of around 500-600 ohms any thing much more than this ie.. 1250etc and i would say the pot is dead... try adjusting it (the screw un the bung you have removed) this should change the reading on the multi meter if it dosent also it is dead..(by the way the meter needs to be set @ 2k ohms) hope this helps..

Dubcharged 0 Posted November 20, 2003 Sometimes the CO Pot is set to very high resistance ie 1250 from a garage so doesnt automatically mean its dead, just try adjusting it and it shoud change resistance. Quote Share this post Link to post Share on other sites
