So, I finally got off my lazy azz and stuck my hand down into the engine area, and sure enough, my hose is collapsing ... so I'm off to the Stealership. I know I can get it cheaper online, but I figure after S&H and my time waiting ... its not worth the savings. Gonna get some MAF cleaner while I'm out and clean that up also.

Yay, new hose in. And man, that factory clamp is a pita. I have the newer hose with the metal heat shield around it. I'll post a picture up of the 2 different hoses in a bit. Haven't had a chance to do enough driving in the "zone" to see if the problem has gone away.

Talking

Many thanks to those in this forum!

My 2000 ZX3 Zetec popped a PO171 and then started idling rough and stalling. I tried fuel injector cleaner, replaced the air filter, fuel filter and PCV valve no change.

I am definitely not a car mechanic type, but I kept looking, finally found out where the other end of the PCV hose connected and felt around under the air intake and found the hose, it had collapsed. I got the the hose from the dealer, old style no heat sink, and replaced it a few weeks ago. That clamp is a bear! If not for the clamp, it would have been a ten minute job. Once I had the hose out, I could see it had collapsed and was cracked.

My car is now running great! Steady RPMs at idle, no problems.

One question: Is the other end of the hose, the one that attaches to the metal tube that goes over the block, is it suppose to slide over the bump on the tube? I didn't get it over that, but I secured it with another hose clamp.

Thanks,

Dave

This information is awesome. 150,000 miles and I have been living with the CEL going on and off for a while, stumbling at idle, irratic idle, stalling, sloooooow a take off, It's gotta be the hose. I'm going to check asap.
