sailor No question that would have a large effect on your problems.

Rule of thumb is to always fix known problems when found, then see what issues might remain afterwards.

callerid15 I just bought a 2001 ZX3 found the whole pcv hose to be collapsed. Could this be causing very slow acceleration. Also have the rough idle and stalling when I come to a stop.

Dave One Sorry to be lazy. Is XS4Z-6N664-BA good for the 1.8 Zetec-E as well as the 2.0? I fancy getting the heat insulated version?

Also if its the timing im just going to go buy another engine cost less and its at 280,000km im gonna test my egr and dpfe see if there is any change i have access to a mechanic shop just no help im relying on you guys so i can keep my wagon

MadFF When was the last time you replaced the fuel filter? It made a noticeable difference when I replaced mine.

beyond_theft ive replaced this hose, still stumble and rough idle cleand the maf and iac valve. I'm doing the mounts but i really dont think it will help. Scanned it has no codes ive tested the idle to figure out when it startes to be rough and sputter starts around 700 and stops at 1100 i used a snap on scanner. I think it is my timing belt could have jumped? i dont think its running lean cant smell unburnt fuel.. any suggestions?

qdeezie I installed the new hose last night and low and behold, the stumble is GONE!!! The car runs like a totally different vehicle now and it accelerates much better too.

qdeezie I'm another victim of the bad hose. I reached around the back of the engine and sure enough, the hose was collapsed. I used a pocket knife to cut it off and a screwdriver to pop the clamp. I'm waiting on my new hose (with the heat wrap around it) to come in.

I'm glad I found this thread.

Error code P2195 on 03 ZX5

Was getting error code P2195 on 2003 ZX5 Focus my wife drives. I replaced fuel filter, upstream O2 sensor, cleaned MAF and throttle, still no luck. I finally took to the 'net and found this thread. It turned out the rear PCV/Crankshaft hose was indeed the problem.

Unfortunately, today was a Sunday so I had no choice but to "frankenstein" a hose together that would work. I just used hoses and some elbows from off the shelf at my local Autozone. Hope this helps someone else, as the car is running better than I've ever seen it.

amc49 A bad TPS switch can really mess with idle and off idle too, just went there last week. Put a manual TPS on ATX to avoid buying the TB, works perfectly now and idle trouble is gone.
