Went through the MOT (German equivalent ) today with no real problems, started the car to drive back home and it wasn´´t running right at all. Sounded and felt a little like when one of my injectors died recently, just not so drastic. alot of vibration on the gear stick and the car is only slightly sounding like a tractor, hesitates when accelerating from idle but runs fine when going over 2500 rpm although when you accelerate you can feel the power isn´t there although boost gauge shows full boost.

 

Could this be another injector on it´´s way out or is there something else I can check ( when the engine cools down ) that might cause these symptoms.

 

As always. any help or suggestions are greatly appreciated.

Cheers Gary, my concern this morning was that it might fail. Then I pass the MOT and the car starts to die...things that make you go "hmmmmmm"

I´ll do that once the engine cools down..cheers for that Paul.

 

I should of however mentioned that the spark plugs (NGK´s) are only about 1000 k´´s old, as are the new coil pack connectors and new injector connectors. Changed out 2 injectors a few months back and she was running sweet ever since...until today :(

Cheers for that Berrica, but she does rev over 2500 with ease, it actually responds better when over 2500 rpm. I guess the best way to describe it would be that she responds and drives as though she were running on 5 and a half cylinders,,if that makes sense. :confused1:

 

anyway..checked all the spark plugs and they´re all fine, as are the connectors. I´´ll check the injectors tomorrow and see what I get there.

I have had somthing similar on both my zeds. I never did get to the bottom of it as it is intermitant. I did suspect o2 sensors. Mine does this on part throttle from time to time, putting your foot down solves the problem and all is well. But mine does the thing where its showing positive boost but just doesnt pull. Most strange!

 

Althogh if yours is running rough/vibrating maybe its the ptu?

I have a series 2 PTU in the car for a while now with no problems at all. Is there any way to test the PTU without swapping it for another one ?
