Guest frazman Posted March 2, 2008 Share Posted March 2, 2008 Hi All, I have just aquired a Supra TT and it goes very well. However occasionally the turbos aren't coming on and she's flat as a pancake?! When the turbo's are on boosts/holds boost very well. It has been suggested that may be problem with the sequential valves? Are there any local owners on here with some technical knowledge who would have a gander the old girl for a drink? regards fraz Quote Link to comment Share on other sites More sharing options...
dwayne Posted March 2, 2008 Share Posted March 2, 2008 does it happen when you drop down down a gear? Quote Link to comment Share on other sites More sharing options...
BASHTHEBISHOP Posted March 2, 2008 Share Posted March 2, 2008 Is it auto or manual? Quote Link to comment Share on other sites More sharing options...
Guest frazman Posted March 2, 2008 Share Posted March 2, 2008 thx folks it's a manual box and i've only just got the car and only done about 30 miles - doesn't seem to happen when dropping down (out of interest what would this suggest if it was happening when dropping down?). Most of the time it pulls like a train but every say 1 in 10 bursts of acceleration it will be flat/very slow acceleration with no obvious turbo kicking in - seems to happen mainly in 3rd gear from my brief analysis from short drive. Will try to get some more miles in tomorrow to establish when the problem is occuring more accuratley. n.b the previous keeper informs me the car had been sat up for a while Quote Link to comment Share on other sites More sharing options...
