TF has not been used much since Xmas...
Last Sunday went out in it(65 miles) and it is playing up, seems very slugish and wont excelerate then suddenly it will be ok and drive normally for some miles and and then be slugish again..
Last year I did the Head Gasket(and Oil Rail), new coolant pump,belt and tensioner, spark plugs and leads, oil and filter and OAT coolant..
No Fault Lights and no Fault Codes on my Scangauge......Any ides?Cheers.

Update:-I suspected it might of been a coil pack playing up, so today swopped the coil packs off the ZR and fitted them to the TF together with some new spark plugs....
Took the car out and tested but it is exactly the same, got home and noticed the idle speed was a bit erratic(850 - 960 rpm).....left if running for a few minutes and the revs evened out at about 930 rpm....
Then the engine light came on, checked with my 'Scangauge' and it shows a PO170 Fault code which is Fuel Trim Malfunction(Bank 1).
Cheers....

On the 45 / ZS theres a large connector somewhere in throttle body area that can play up and cause allsorts of trouble. DFon't know if the TF has same connector?
