Hey All,
I have a 2004 Suzuki Forenza, 5spd with ~45k miles. Over the last two weeks I have noticed exhaust fumes in the passenger compartment during this scenario:
-Blower is on
-Car is stopped for more than 3-5 seconds
-Only when car is fully warmed up
-Hot/Cold temperature selector doesn't matter
-recirc solves the problem completely
-What I had done:
-removed leaves and debris from intake between hood and windshield
-checked exhaust manifold for cracks
-checked exhaust pipe connections to cat for any leaks and/or soot
-Looked (the best I could) for vacuum lines or something that might have become disconnected
-Checked PCV
Does anyone have any other idea what could cause this all of a sudden and only when the vehicle is completely warmed up? This car does do most trips between 1 and 3 miles, stop and go in the Denver area. On another note, I had 10 gals of fuel that was 1 year old with a double dose of stabil in it. I change it out annually and usually put it in my truck. Truck was full so I put it in this car. I can't remember if the fumes started after that or not but it seems it might have been around the same time. Could that cause the problem? Car is down to
1/2 tank and I figure when it gets to 1/4, I'll put in fresh fuel.TIA,
Derek
