Air Filters
Air Filters
Yes..I have to ask this question I posted a few days ago that my car was hesitating when I accelerated from a stop and also that it wanted to stall at lights. I received a couple of responses to that saying that it might be my crankshaft position sensor. MrMiata found one on Ebay for me which I purchased and then he walked me through installing it in my car. That didn't solve the problem so he just wondered how my air filters were looking. I just looked under the hood and don't see it..maybe if I pulled it out of the garage I'd have better luck locating it . I'm assuming there is a cabin filter and it's probably on the underside of the glove compartment. I'm driving a 2005 limited if that information is necessary. I checked the forum before I posted but couldn't find anything on changing the air filter. If they look okay, then I'm unfortunately heading to my mechanic this morning. Thanks in advance!

Re: Air Filters
The intake filters are in the shiny-plastic-looking cover over the engine. You pull up on the back of it, it will pop off and then you disconnect the two black hoses at the front.
Taking the assembly off hte car, turn it over - you will see the two covers, one on each side. Remove them using a screwdriver. The filters are inside the housing.
The Cabin filter just filters air to the cabin - has nothing to do iwth the engine.

Re: Air Filters
I doubt it is the filters, unless you live in a real dusty area and they have not been cleaned lately. I say it could be a fuel filter or pump. It is hard to say though.

You'll need a torx bit, probably size #25, for the screwdriver. Make sure it is the biggest size bit that fits the head of the screw.

Re: Air Filters
Well, they do look pretty bad. And they will affect your overall performance and fuel consumption. So no one else has suggested cleaning the Mass Air Flow sensor, either. But I'd give that a try too, as well as checking the battery. Do you still have the original white one? If so, a voltage drop can give the computer problems and affect the throttle function and idle.

Re: Air Filters
Here's a general link on the MAF -
and another on actually cleaning one.
This was not done on a Crossfire - I think that it's VW - but the principles are the same. Don't worry about the clamps, etc. Watch the process and you'll see the similarities from the air filters and on. You can probably just spray the internal parts sufficiently without the full disassembly.
Just managed to find a K&N but they have to order the second to pick up later today. I also picked up the mass air flow sensor cleaner and throttle cleaner. Wish me luck because I am nervous about the last two!

Re: Air Filters
If the battery is white, it's a Varta and PROBABLY original.
They are supposed to punch out the year and month of purchase, that's how you know when the warranty starts, so yes, there should be indication of install date.
The fuel pressure regulator and fuel filter are all in one unit. They sell in the aftermarket world for about $30. I've never tried changing one, I think it's four hoses and four clamps, not very involved, but there will probably be pressurein the lines when you loosen the clamps, keep that in mind!

Yes there is a constant pressure in the fuel line.
This may be of help and there are many other places here that discuss fuel filter changes as well.
I've heard the clamps can be quite tricky and this filter and pump are located together underneath the car in front of the right rear wheel

Re: Air Filters
But that video link said that you can tell if you need a new one if you unplug it and the car acts normally..or almost normally, although I'm not sure what almost normally means. I was hoping, if I do this, that I could drive it because that's when I notice the problem. I wouldn't even have to get out of my neighborhood to hit a few stop lights/signs to know.
Re: Air Filters
I wouldn't worry about all the testing. Do your best with the aerosol cleaning process because it won't hurt anything to clean it as part of a general maintenance item, put it back together and go for a drive. This is a simpler thing than the fuel pump and fuel filter, and you want to eliminate the simple things first. If this fixes it, problem solved. If not, you can look into the next issues.
