Just slow down a bit and explain

 

1. What engine exactly it is i.e. what bhp

 

2. Describe "power loss" in more detail - does it have initially have full power and "trip" into limp home mode when you try to accelerate. Or is there no power all the time?

hi

it runs realy well for about half to one mile then it goes into limp mode or if i push it uphill or on flat 500 yds and it goes into limp turn ign off on and it resets for same amount of time if on motorway as long as i dont push i can get 70 no prob as long as its flat

i think its 110

Hmm....similar problem as GSMGUY.....

 

It could be

 

1. leaks/restriction in the vacuum system

 

2. Turbo actuator mechanism problem (sticky)

 

3. Turbo (Boost) Control Solenoid

 

4. Leaks/restriction in the Boost Pipework/Intercooler

 

First, check your air filter is not blocked. Has it been changed in the last 20k?

 

Second, check all the vacuum pipework and fittings, are they all connected? Take the pipe off the ATM connection on the Boost Control Solenoid and see if it makes a difference, if it does then the faults somewhere in the vacuum pipework.

 

See this thread and this thread for further info.

 

Let us know how you get on....
