Where is the PCV valve on a 2002 Chevy Impala?

The car has a rough idle and also some gas fumes in the car. Could a bad PCV valve cause this.

    About a month ago, started to smell gas in the cockpit. Raised the hood and found that gas covered the Fuel Pressure Regulator, kind of like dew. Doesn't happen every time I start it, but, today...I started to get a surge upon acceleration. Got home and did some revving to check the surge and found that at higher rpms, the engine surged or roomp, roomp, roomp'ed. But, the FPR is dry. Checked vacuum and there's plenty going to it, so it must be a bad FPR.

This sounds like a possible bad fuel pressure regulator.
Depending on which engine (3.4l or 3.8l) they can be easy or hard to replace. For pics on the 3.4l regulator replacement, see this link...

IDLING PROBLEMS ON A 2006 CHEVY IMPALA


I had a similar problem and it was a dirty egr exhaust gas recirculation valve. Could also be a idle control valve that is weak and not setting a code.

My 2001 expedition is idling rough and i hear a hiss comming from the engine near the rear but cant tell were its comming from


There is a large elbow shaped tube at the back of the intake plenum where the PCV valve hose connects. This tube gets a hole sucked in it due to oil fumes that come through the PCV valve and softens the rubber. To find the tube,simply follow the PCV valve tube from the valve cover on the passenger side of engine to the back of the intake.

sound like idle speed low idle you need to remove throttle body clean entire throttle body spray cleaner down throttle body bore if cleaning throttle body dont help the dealership has to check it out.a faulty egr valve could be stuck partially open that will cause rough idle and stalling. replace air filter clean fuel injectors.your fuel system could be too lean caused by clogged fuel injectors or weak fuel pump check fuel pressure and also check all intake vacuum hoses make sure pcv valve working should have suction and make sure its in place and the pcv valve hose not cracked open or damaged.

1993 3.4l camaro Idles fine when first started. After a few seconds it idles rough and rpm drops. No power when driving. RPM will not go above 3000 even if floored when driving.


there are a few reasons to ur problems 1st check and or replace fuel filter -check and or service egr valve -carbon usually builds up in and around valve causing rough idle -no power and can cause non start problem ---also air filter - fuel pump-bad gas -timing skip-pcv valve-catalytic converter clogging these are some of the problems usually one of the first 2 is the problem good luck

I gotta 1997 toyota avalon its running rough i ran a scanner it threw two codes po441 an po402. i need help figuring out wat these codes are


Hi there osborne_shay,

Those codes refer to a problem with the drive train in your Avalon. Here is what the codes mean.


PO441-Evaporated Emission Control System / Incorrect Purge Flow
PO402-Excessive gas flow through the EGR valve

The cause for these issues are either that the components are faulty or they just need to be cleaned.

Car is stalling at idle


Several possible problems associated with stalling @ idle.
  • Bad PCV valve
  • Bad fuel filter
  • Bad TPS (throttle positioning sensor
Most chain auto parts stores will run a free diagnostic test for you. After getting the codes, it will be easier to narrow down your problem.

Chevy 2002 Malibu ERG valve


Symptoms of a bad EGR valve are usually stumbling idle or the engine stalling when the car is warm (normal operating temperature). Find the EGR valve and locate the vacuum line attached to it. Start the engine cold and wait for it to warm up. When the engine starts to stumble, pull off the vacuum line. If the EGR is bad, the engine idle will stabilize and no longer stumble.

Hi,
You might get some gas treatment for your tank. Sometimes bad gas can cause those symptoms.
I would put the treatment in and let it sit overnight. Hopefully the next morning the car will feel better!
I hope this helps... Good luck!

doubtful,try spraying the wires and plugs with some windex with the car idling,listen and watch for spark jumping. Plug wires are often the cause.
