thanx guys ,well i took ur advice and went and got a test done on car,2 faults came up -

partical filter

exhaust sensor on rear of manifold

ive been quoted €450 euro for the partical filter and €120 for the sensor

now the guy in the garage before he put it on the diagnostics took it for a drive and said he dident really see it been down in power!

he put it on the computer and it went thru the various tests and during this it kept revs at 3000 revs for 3 minutes-the guy said this was to clear the fault with the paertical filter,at the time it done this loads of blackish smoke came outa exhaust

so he tested it again and watever reading he got in 1st place which i think was 530 was down to 0-

he said that the sensor at the rear of the manifold was faulty as it stayed at 140 throughout the test so dat needed to be changed

at the end of it i was charged €40 for the test,the guy said to drive it for a couple weeks a see how it goes

problen is i dunno what to do now ?there is a slighly more power in it now

do i change the exhaust sensor and what difference will it make ?

and will it give me more power?

also can this sensor be changed by myself ?-is it easily accesable ?

cheers paul
