Coonper 0 Posted January 14, 2008 I put my VR6 on the diagnostics recently due to a missfire at low revs and it said this... "idle air control regulation and engine speed sensor no signal" Any idea if this would be expensive, and how easy is it to fix?? :( Thanks in advance Quote Share this post Link to post Share on other sites
andygal 0 Posted January 14, 2008 speed sensor for get about...due to the fact the engine was not runnig. the other one sounds like your ISV. Expensive new (about £180???) but can pick them up 2nd hand fairly easily! Cheers, Andy Quote Share this post Link to post Share on other sites
Coonper 0 Posted January 15, 2008 Thanks for the reply. Could it be this sensor which is causing the missfire?? It only seems to do it at low revs. Quote Share this post Link to post Share on other sites
