Shaggy 0 Posted December 21, 2005 I have got my Piper 270 cam in now, and its been in for about 500 miles now, just wondering how lumpy the idle should be with a cam like this, i have noticed when warm that it tends to idle a little rough... like its miss firing ever so slightly etc etc, it runs almost perfectly apart from that. the car hasnt been properly setup by darren and G-werks yet, so i should think this might help it a little? eveything is lined up and the timing set correctly. Maybe i am just being a little to paranoid 8) Quote Share this post Link to post Share on other sites
CorradoVR6-Turbo 0 Posted December 21, 2005 High lift cams will never idle as smoothley as stock.Was it just cam that was changed or other head work? Quote Share this post Link to post Share on other sites

Supercharged 2 Posted December 21, 2005 May be just the nature of the cam but see what Darren says... Quote Share this post Link to post Share on other sites
