datsun40146 Posted December 23, 2008 Share Posted December 23, 2008 Hello Hybridz! It’s been a while since I've posted but I bought another 280z from Cali and let me tell you. I will never buy another east coast car again. You haven't seen rust free until you've seen this car and I got it for a song. This car would’ve cost 5,000 at least on this side of the country. Anyway that was the preface. The car was a weekend driver in Sacramento and I had it shipped to Ky. It drives GREAT except for an issue that I can't track down. When you take off in the car in 1st is has a multiple bad stutter/hesitation at around 2 to 3 thousand rpms. This only happens on takeoff and it will do this if it’s warmed up or not. I can free rev the car all day and it will sing right to the red line. I changed all the filters and added an inline fuel filter (Fram g3). I cleaned all the contacts and adjusted the valves replaced the plugs, cap, rotor ect. I am just about out of ideas here. Does anyone know what would cause the problems I am having? One more unrelated thing; this car hates cold weather do you think the CSV and or the by-pass valve are bad? I think that in Cali they would never be used. Anyway that’s it. Thanks Quote Link to comment Share on other sites More sharing options...

datsun40146 Posted December 29, 2008 Author Share Posted December 29, 2008 I have cleaned the afm to no effect and have already ajusted the tps and watched for movement as I worked the throttle. Quote Link to comment Share on other sites More sharing options...
FlatBlack Posted December 29, 2008 Share Posted December 29, 2008 It only happens in first gear? Have you taken the black cover off the AFM? Quote Link to comment Share on other sites More sharing options...
