mfi or efi m8 ? If mfi spray some carb cleaner into the metering head.

 

i had a similar problem, only happened when the car got warm. i put in a new idle speed control valve (auxillary air device) and its been working fine since.

check the hoses on either side of the valve as one of mine had come loose causing an air leak.

 

its MFI and its fine when you first start her up but when warm the problem start's were is the iscv situated as for spraying into the M head i take it you mean take off the air filter and spray it on and around the flap?

mines the other way around

idles once warm but cuts out when its first started for 5 mins

 

its underneath the inlet manifold at the back of the engine bay.

its a bit fiddly to change it over especially from the top of the engine but i managed and im mechanically inept at the best of times!

 

mine was doing the same thing after trying too get it right for about an hour took my filter off and the flap was caked up in sh*t cleaned it off with carb clean and it runs spot on

 

anymore for anymore?

hi patto

in all the years of tuning rs turbos i have never had to change an auxillary air vavle as long as the m head is clean, you have clean oil brether pipes and the dipstick has not come out. all it will need most of the time is the base mixture setting as this is a mecanical system a can go out of tune very quikley the best thing to do is to have it all set up on a rolling road for the best resault.

 

thanks for the replies im gonna spend the day 2morrow checking all the pipes and cleaning them up if that doent solve it its time to take it to a tuner. have found a hole in my rocker cover gasket and theres oil spewing out so maybe this wont be helping!

Nice one m8.

 

after i thought i had cured my idling problem i now have the same problem as Patto had.

Where can i get some carb cleaner from or can i just use something like WD40 just to clean all the crap from the inlet pipes.

 

ok took the air filter off earlier and cleaned as much as possible but can anybody tell me how to get rid of the black gunk which sits on the bottom of the metering head. looks real mank.

 

I disconnected the cold start valve on mine, makes no difference

 

You can get carb cleaner from any factors m8.

 

managed to get some carb cleaner off my mate who works for wurth in the end. gave the 'flap' a good clean, am yet to test it out due to rain stopping play recently.

went to halfords and they were fucking useless as always.

pointed me in the direction of the nearest polish

my idling problem is real intermittent though, it will go through a period of idling really low then sometimes it will rise again.

am gonna give my k+n filter a clean as well see if that helps....

 

A good couple of sprays should be enough m8.
