It was me who said my Multi jtd was revving up to 5000rpm. There was at the time untill today a fault with the following parts, throttle potentiometer, Mass airflow sensor, a temperature sensor and finally the EGR valve. The symptoms at the time of taking the car to the dealer was below 2500 rpm it crawled...literally crawled along. At about 2500 rpm it took off like a scalded cat to about five thousand revs, the wheels, on damp roads on the day, were spinning uncontrollably, due in part I would imagine to the throttle potentiometer playing up. Plus, at the end, the amount of smoke coming out the back you would think the car was on fire! When at the dealer we all agreed the car was unsafe/unfit to drive. Due to circumstances I wont go into, the car had to be trailered to another dealer twenty miles away for work to be done other than the diagnostic work to determine all of the above faults, with the exception of the EGR valve. Once the sensors were replaced the car drove well until it got hot, at that point we had the smoke problem again!
This was yesterday diagnosed as the EGR valve and was replaced today, (Sat). (Well done TJ Vickers of Telford) The car now drives beautifully and performs as it should. I have just come down the Telford Queensway and it accelerates straightaway up to about 4800rpm without any hesitation. This is not something I normally do I must hasten to add. It was because the car was freshly repaired and had to be thoroughly tested...officer! I normally never get above about 2500 rpm unless on the motorway which is why I never realised untill the throttle pot went that the car was faulty.
Finally, if your car wont pass 4000 rpm, two thoughts, are you trying cos it should and throttle potentiometer! That is exactly like mine was this time last year when it went then too! They are not proving to be that robust!
