My car is not driving very nice when cold it's lumpy unresponsive and generally not nice when its cold at normal speeds.

Also it's making like a howling noise at about 3500 rpm, it's not loud but I was just wondering if its normal

Any ideas please.

 

Forgot to add its a 2005 sti ppp

 

Do you have a aftermarket bov fitted?

 

No mate standard apart from ppp

 

You had a check around the engine? I had similar symptoms after the hose on the recirc valve came loose.

 

Worth checking all other hoses as well mate.

 

CTS coolant temp sensor

 

Just had a good nose around and there's nothing obviously loose or split so I'm stumped lol

Once its warm its fine

 

Ill get this looked into tomorow, cheers

 

Would that cause a howling sound? Can it be dissconected to diagnose that its the problem?
