Message	Mine will dip on idle if I lightly tap the throttle while it is still cold. If I try to drive it before warming it up, it will "buck" on me a few times until I let off the gas and then hit it again. However, if it is warm, none of this happens. It is fairly reliable other than when I do quick stops and then it stalls (I blame the DOOLZ for that part though). I have Nismo 740cc injectors, dual intake (DOOLZ), and a Specialty Z chip in my ECU. It's been happening ever since I got the car put back together after the rebuild. It does have some boost leaks that I am trying to track down but, at the same time, it is running lean as per the dyno sheet. I'm concerned because, once the boost leaks are fixed, it will be even leaner. I have no idea why it would be running lean with new injectors and a SZ chip. I really need to fix these issues soon. How similar is this to your issue? ----------------------------------------------------- Never Play Leapfrog With A Unicorn!!! Do yourself a favor and just worry about your own car. I don't see what everyone is so worried about anyway. If someone else wants to perform a modification that you believe will destroy the value, cheapen the Z32 or whatever you can't sit on your hands about, wouldn't that make your tastefully-modified, white bread Z32 more rare and valuable? -- BradZ (FL) on December 23, 2007 at 12:19 PM The unicorn gets its revenge... -- Scotts94z32 on September 19, 2006 at 11:12 AM CLICK FOR DETAILS ABOUT BUYING A ZAMA POSTER!!!!
