Hi all
Trying to diagnose a P0172 Fault Code (Check Engine Light) on a 98 S70 Non-Turbo 96k miles. So far, with the help of a write-up at Volvospeed.com, I've found that the Cheap, Brittle corrigated plastic tube that goes downwind from the Air flow Meter has several small cracks when the band clamp connects. I'm toying with either of these ideas:
1. slap some epoxy on it and call it a day.
2. Fab up a new hose. The dealer (Brentwood Volvo) wants $30 for it!!! Ouch!
Any thoughts on this??

The other potential problem is the Rubber elbow that goes on the rear of the Intake Manifold by the power steering pump. I looks as though it is really soft and sucked itself closed. That's only a $2 part so I dont really care about replacing it.

Please tell me your thoughts! Am I barking up the wrong tree? Gas milage is not too good since the Fault Code popped up. Please help!

Hi Guys, can you tell me if youe Check Engine light came on with these vacuum leaks

I had a code - don't remember the number - regarding fuel mixture or trim. Car sometimes idled a little rough. The fresh air hose had several cracks. Put in new hose bought from dealer. Code has not returned in a year. I would not patch the hose as whatever is used might get loose and get sucked in under manifold vacuum. Also the hose needs to flex as the engine moves quite a bit as load is applied/removed.

same code, later suddenly became p0102, i'm buying a new MAF

Suck it up and save you the headache...buy the $30 hose. I seem to have the same problem but don't know the part number. Could you tell me what it is and I'll see if it could be gotten for less.
Regards,
MIJ
