COLIN WELLS

Thank you all for your responses to my enquiry regarding my Jaguar S Type. I can replace the Air Filter myself then if that doesn’t solve the problem I will suggest your other possibilities to the Jaguar Specialist. Best regards Colin

I own a 06 Reg. Jaguar s Type 2.5 V6 Manual. When I carry out hard acceleration in all gears the start of the acceleration is ok but as the revs increase suddenly the engine cuts but not completely stopping. The orange Engine management starts flashing and a warning is displayed - “Restricted Performance”. The Engine keeps running and the light flashing but I can only travel at low speed, around 30 mph. After about a mile the flashing orange light stops but is still displayed and the Car will then drive as normal. Under normal driving up to 70 mph the Car is fine but this problem only comes to light under hard acceleration. I notice it mainly in third gear but it will still happen in other gears. I took my Car to a Jaguar specialist and they changed the Spark Plug Coils, the Fuel Metering Unit and one of the Catalytic Converters. I still had the same problem so I took it to another Jaguar specialist who cleaned the Fuel Filter, removed the 2 Caps to access the twin Fuel Tanks under the Rear Seat and replaced one of the Float Mechanisms. He also replaced the Fuel Pump. After all this I still have the same problem. I have been told that in the Manifold there is a Butterfly Mechanism that can stick but don’t know if this is the case. Has anyone else come across this problem with the Ford designed 2.5 V6. I would be grateful of any relevant information to solve this problem.
