Message	I have a surging when driving at a constant speed (ie when not accelerating or decelerating). Its like hiccups when just cruising at speed (like when the cruise control is on), but it does not matter how fast or slow I am going as long as I am just at a steady speed and in any gear. This to me seems like a fuel issue. Could this be related to the lean-ness or you have any suggestions? I would come to your shop if I was not so frickin far away =0( 1990 300zx 2+2 TT White w/ Blue Pearl Stage IX+ "She may beg, she may bleed, she may argue with her logic and mention all the things I'll lose, that really have no value, in the end she will surely know, I wasn't born to follow."
