Jonester 0 Posted April 1, 2005 Upon starting my VR6 revs go from 500ish to 1500ish continually at idle. Then, when I drive her this continues but only whenever I come to a halt. The battery light is also flickering (brand new battery so no problem there) when the revs drop to 500 and she stalls constantly. Any ideas before I let some halfwit grease monkey loose on her???

Supercharged 2 Posted April 1, 2005 Have you tested the alternator?? You should get at least 14v across the battery with the engine running.. Quote Share this post Link to post Share on other sites

stevemac 0 Posted April 1, 2005 Jonester, Revving at idle (hunting) is usually, not always, caused by either a vacuum leak or an air leak. When the engine drags air in, possibly from a leaking inlet manifold gasket, it will display symptoms as you describe. Quote Share this post Link to post Share on other sites
Supercharged 2 Posted April 1, 2005 Steve, is there an easy way to tell if that gasket is leaking?? Quote Share this post Link to post Share on other sites
stevemac 0 Posted April 1, 2005 Steve, is there an easy way to tell if that gasket is leaking??Dead easy - spray some WD40 over the gasket while the engine is running. The engine revs will pick-up if the gasket is leaking. Don't be tempted to use brake cleaner or carb cleaner instead of WD40 - they're too flamable & may catch fire.

Chris VR6nos 0 Posted April 2, 2005 I had a similar problem with one of my VR6's and it was a failty MAF, changes it and it ran great from that moment. Chris Quote Share this post Link to post Share on other sites
