Jonathan1976 0 Posted July 19, 2006 I've just had the fuel metering head reconditioned and the guy at Southern carburetters tells me there is an electrical misfire and its nothing to do with the fuel metering head. This only happens when the engine is at idle revs drops from 1000 to 300rpm and then finds itself again. Only happens when the engin is warm. At higher (2000rpm) there is nothing at all. :twisted: Quote Share this post Link to post Share on other sites
Crasher 3 Posted July 19, 2006 Get a fault code report. Worn injectors can cause an inexplicable idle misfire when they get very high miles on them. Quote Share this post Link to post Share on other sites
Jonathan1976 0 Posted July 20, 2006 UPDATE: I've been told it could be the coil and amplifier unit? The fault code showed up with nothing. Quote Share this post Link to post Share on other sites
Guest Posted July 20, 2006 Check the timing. Make sure all the cam and crank pulley marks all line up, and that the dizzy is retarded to the correct angle. (im assuming this is a 16v?) Crank was one tooth out on my VR, and cams didn't line up on the girlfriends polo, both causing an erratic idle. It disappeared once corrected on both cars.
