Henny 0 Posted July 15, 2005 G60Dan, a vacuum leak will cause this, also a non-closing throttle switch will cause an erratic idle... (had both of these just after I did my engine swap :oops: :lol: ) Quote Share this post Link to post Share on other sites
G60Dan 0 Posted July 15, 2005 a lot of the time is stables it's self. It's just every now & then, mostly when cold the idle drops & then tries to compensate & then drops again and so on. Never enough to stall, just enough to be annoying! Quote Share this post Link to post Share on other sites
