They are both part of your emission system
Fuel filter.Fuel filter.
PCV valve and catalyic converter.
very little, probably had a PCV valve.
That is the Positive Crankcase Ventilation ( PCV ) valve Depending on the model year and engine size there are different part numbers for the PCV valve
Your PCV valve is a simple plastic piece of plumbing that performs a not-so-vital function for your engine. The Federal government, however, thinks it's very important. In reality it's an important part of your car's emission control system. If your PCV valve becomes clogged, your emission controls can't function fully, and the results are poor idling, loss of gas mileage, slow acceleration, loss of power and other similar ailments. There isn't a consensus on how often the PCV valve should be replaced, but somewhere in the neighborhood of 30-60,000 miles seems to make sense
Emission parts contain a number of things such as; spark plugs/wire, O2 sensor, pcv valve, vapor canisters, MAP sensor idle control valve, etc
get a chiltons or hanes manual for emmisions. I bought one and the first time i used it i saved 200 bucks. turned out my problem was a 3 dollas pcv valve.

No.No.
pcv valve
I have read that a bad PCV Valve will contribute to gunking up your Throttle Body, which could lead to irregular acceleration issues. I am certain that there is more to a bad PCV Valve than that, as this is an Emission Control item, but hopefully someone who knows more will chime in. SUBMITTED: Friday, 03JUN11
