TubbyZ Posted February 3, 2020 Share Posted February 3, 2020 Hi guys, This problem has been getting worse on my car to the point where it's shown new symptoms. I have an 07 HR 350z. When warmed up the car sometimes judders / bunny hops very intermittently (like once every 30 or so times i set off). The other day though I was driving at around 80 and put my foot down, my car just juddered and didn't pick up any speed. It didn't seem to go up in revs so it wasn't like the clutch was slipping. Could this be the differential? Sometimes when I put my foot down there is a delay before the power kicks in like a second or so like it's sluggish. I really don't know how to explain this to garages and what they could check because I've had it checked over before and they haven't found anything wrong. Thanks, Toby Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted February 3, 2020 Share Posted February 3, 2020 It could be numerous things including cam/crank sensors etc. However an up rev tune may fix your issue,. Take it to a 350 specialist who can perform the uprev tune. Quote Link to comment Share on other sites More sharing options...

It makes some strange noises too like clunking when changing gears. Unsure if it's possibly the diff? Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted February 3, 2020 Share Posted February 3, 2020 Take it to a 350Z specialist for an informed diagnoses as it is only guesswork from where I am sat. All drive train parts are in stock if required. Quote Link to comment Share on other sites More sharing options...
