ok so the problem is probably the pcv thing right? well here is some interesting info from my recent case of the chivers. When it started doing it i let it run all jerky for a bit then turned the car off and turned it back on. It was gone not a sign of jerkyness remainging. so would that mean that it was something electronical or could it still be the pcv.
Seems like a lot of us are having this problem i wonder why it has never really been dealt with before. |

So anyone got anywhere??
ok news update from me PCV changed, all hoses i could find related to PCV system or vacuum hoses- changed...(still could not locate some ) pcv system works now, no oil dipstic poping up... like wow all should be cool now (i had about 5 vacuum hoses in terrible condition and all PCV related hoses) but nah.. car idles even worse now... but i ve done good 10,000kms since it started to idle rought... so something goes worse progresivly im still trying to locate another 3-6 vacuum hoses (i disconnected 1 accedenly while changing the other one... so trying to find all of them and check) ok so far i can only advice to make sure u have ur 2 vacuum hoses going off the throttle body top (the left one is thin about 4mm inlet the right one is thicker and is 1/2" inlet) as they matter so much for how the car opperate [left one goes to pressure regulator, unplug it and car sounds like V8 holden and consuming hell lotta petrol, unplug the right one u hear whistling and car dies immidiately] i had both hard as stone... so good idea to check them anyway also here s the pic of vacuum diagram. Could anyone tell me what followings are for: (on the picture) EGR valve EGR vacuum control EGR solenoid valve VC tank Purge Control solenoid valve Check valve Canister Actuator Induction solenoid valve would be usefull to know.... |

sputtering and rough idling
Hi
This is my first post. After reading about the sputtering and rough idle several of you describe I decided to share my own problems. This has been going on for almost 2 years and started after I changed the spark plugs. In contrast to what I've read, the rough idle does not happen soon after startup but only when the engine is hot. The worse thing I can do is multiple short errands over a few hours. That gets the idle very rough and makes the car shake. No difference if I change gears or stop and restart. Roughness disappears when I hit the gas and is only seen at idle. I've read elsewhere that it's easy to damage the coils when changing spark plugs and since the timing works out, I'd like to blame that. But from what others say, changing the coils might not fix anything. Any suggestions would be greatly appreciated. Simon |

and i ve got no clue what it can be.... i guess the only thing i ve got left to do is change the sparks back and think the new plugs were factory damaged or something.... even tho i can suggest i damaged coils but it seems to be petrol problem and not separate cyllinder... anyways what ive done is described above... so far its not going better |

ok so mine started randomly spark pugs were still old. Get this though my dad took it to a mechanic to replace the belts and he mentioned this problem. dude drove it and said it was "vapor lock" now i dont know if i really by this or not but could it be? if so how do i take care of it.
p.s. so the dipstick getting pushed out is the pcv valve? |

I just meant the dash lights came on when it stalled - she does not have a check engine light.
I am thinking of trying temp sensor swaps next.

I'm checking the vacuum with a gauge mounted against the windshield right now (pathetic, huh?). Pretty soon I'll contact a psychic. Don't know if you have exactly what I gots, but the temperature sensor (easy access, cheap) is one of the first things I tried. I know this sounds a little wacky, but the things that seem to help(not solve!) this intermittent problem the most is fuel cleaners (including ~1 oz./tank) or octane booster (?).

so its not only me going mad about the car jerks
uh huh... its gettin worse for me i think... so soon ill be stalling... and then... then i better fix it ... or ill be really really pissed off!! anyways back to posts: [quote] p.s. so the dipstick getting pushed out is the pcv valve? [quote] if dipstick pops up: first get some insultion tape and get around the top of dipstic, so it will be tight when u push it back. if it still pops up then its pcv system (mite be just cracked hose or can be stuck PCV valve) changed mine pcv valve and hoses, still same and even worse... (dont i just cry here?) Quote:
as mine is only when it warms up... when its cold its perfect! (better virse versa ) Quote:
how car would run? petrol consumption? (as unplugging the vacuum hose to pressure regulator may fix the rough idle but give u moster petrol sucker! instead of SVX....) [quote] Don't know if you have exactly what I gots, but the temperature sensor (easy access, cheap) is one of the first things I tried [quute] sounds reasonable to me as its next step i was gonna try... my temp on the gauge is really low, and not half of scale as its supposed to be... but 1/4 of scale... so mite be temp sesor... coz engine feels hot as hell (compared to other cars i had before...) where is it located? or there are 2 sensors there? cheers |

Is there more than one temp sensor in there? I seem to remember most subarus have 1 for the dash gauge and a separate one for the ECU. If someone can point me in the right direction I can swap them.
I still dont understand how it could be 02 sensors, but I can swap those too if needed.
