Hey everybody, I am trying to chase down a vacuum leak somewhere and I'm wondering about the booster near the firewall? It has a little play in it where the 90* elbow mates up with the metal part. It's not much, but it moves in and out and I'm wondering if this could cause a leak? Or is this normal? There isn't all that much oil there that would indicate a leak, although I've read on here they are prone to it. I have some pics of what I'm talking about and am going to try and post them. Thanks.

 

Not sure if you can see in the pics. Thanks again.

 

OK, so now that I look at the sheet from AutoZone more closely it is code P0456, small leak detected in the EVAP system. What does EVAP stand for and where is the best place to start looking for that?

 

The vacuum pump is a known problem spot on these engines. Mine was loose and leaky for months and never gave me a code. EVAP leaks are leaks in the evaporative system that traps and burns off fuel vapors--basically one of the many emission control systems in the car. For a small leak, try the N80 valve (also called the EVAP Purge Valve). It's not expensive, easy to get to, and a part that fails. If you

This might hep understand the system:

 

I replaced the N80 valve. Pretty easy btw. When I checked the code with my torque pro it said I have a pending code p0444. I was able to clear the CEL yesterday after the valve replacement, but today it threw the code p0444. Anyone know where I should check next? It a 2.0 btw.

 

Sounds electrical. Double-check the connector as well as the wiring in that vicinity. May have a broken or loose wire.

 

Ok, thanks. I'll take a look this weekend.
