Re: where is the PCV valve on a 2002 Chevy Impala?
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... Tech JK ----------------------------

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.
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
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.
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!
