Recently my focus has been acting a little funny. Earlier this week the engine started to stall out whenever the car has been in park or neutral. What happens is that whenever the car is idling the rpms drop so low that the engine just stalls. Even when I am driving and I go to neutral it stalls too. There is no check engine light on either.
I just replaced my spark plugs (not the wires though, they are ok) and changed the oil and filter but it didn't help.
I also recently had my mass air flow sensor replaced about 2 weeks ago so my initial thought is an air flow issue however I can not find any holes in or tears in the tubes. There doesn't seem to be any issue with air filter or boot either.
So I thought that maybe it could be an issue with the idle speed control valve or a faulty sensor. I'm thinking about bringing it in to napa or advanced so they can use a scan tool, possibly come up a code. I'm not sure if this will work, however, due to the fact there is no check engine light on (which is in perfect working condition).
So basically I just wanted to know if anyone out there had a similar issue and how they dealt with it. Also if anyone had any advice.
Also I have a crappy cold air intake that the previous owner bought.
have the same problem?
