fse boost valve on a non turbo car, What does that do. Has the car just started doing it or have you fitted any mods, then its started...

i had a 2l sport before and fitted it with boost valve and i had nothing but problems with it and never managed to set up right. it didnt like induction kit on it ether. is ur fuel filter chocked?

The power loss is due to the "non turbo" I personally would try reomving the boost valve and if that dont cures the problem then try the induction kit.

scoobypezz09

right , ok ill try the fse boost valve tomorrow and if not try the induction kit after and ill keep you posted.

i bought the car with all the mods on it , and have only owned it a couple of weeks .

thanks for all replies :-)

If it has a immobilizer, it might be worth getting it bypassed. My old sport developed a missfire and wouldn't run for longer than 3 - 4 minutes at idle without stalling.

Turns out the security system was on its way out, and strangely enough more of the same unit followed on other cars.

had a diagnostic done today and it read a fault with the right hand side lambda sensor ?
needs replacing apparently ?
would it have that effect on my car ?

thanks again in advance !

Yes. Could well be that then. If not you have ruled something out, it's all part of the fault finding process.
