Can anyone help me with an annoying boost problem please? , My small turbo escos is misbehaving . Basically, when I floor the accelerator, it is fine , it goes into over-boost (about 1.2-.1.3 bar)then drops into the windowed area (approx 0.9 bar) as it should do and holds. However, if I part throttle the car, i.e 3/4 of the throttles travel, the car will accelerate to the throttle setting, then if I hold it constant the boost will swing slightly over, then slightly under and slightly over again repeatedly . I have replaced the re-circulation valves diaphragm, and the turbo is brand new (2000 miles inc a new actuator), all the tubing to the the amal valve, actuator and re-circ valve from the inlet manifold is perfect, and I really cannot think what else it possibly could be Has anyone got any suggestions please

 

First thing I always suggest is get a code reader on it to see if the eec's stored any faults. This kind of problem is often because of a sensor giving duff information to the ecu.

 

will ive got a code reader at my house if you wana come round to use it mate, my code reader can also delete and reset the ecu so if it has got any faults we can delete them as well!! give me a call mate if you want to come round to use it

 

Sounds like an offer you cannot refuse Some garages charge silly money to do this.

 

that would be diamond byron will be some beer in it for ya , I'm home next week mon/tues

 

will its no prob matey!!! will be a pleasure!!! how about next wednesday?

give me a call and we'll meet at the same place and you can follow me back to mine, then afer were done a nice pint and a chat!!!

if its the same as the focus then it'll defo work
