Yes, same basic function.
No
Nope. Blow off valves vent to the atmosphere (loud), a bypass does not.
the pcv valve is located on the valve cover, on all hondas....usually towards the center, open the hood and look for a black plastic right angled fitting with a rubber hose coming off of it and leading back into the throttle body.. if you don't know what the throttlebody is, here is a hint....the lever that you can rev the motor with under the hood is on it, and the cable atached to the gas pedal rolls over the very same lever! throttle cable throttle valve they're both on the throttle body zoom zoom The PCV valve on a '99 Accord is located on the rear valve cover all the way to the right side. It is covered by a black plastic trim panel that will have to be removed (two bolts)to access it.
yes they are in a 1994 chevy silverado and is located on the left side of the throttle body.
4cyl back of intake near throttle body// 6cyl roughly same area
Engine braking is caused by the vaccum of the engine attempting to pull air through the closed throttle valve. Nearly all petrol (or gas for us in the US) engines use a throttle valve. Diesel engines on the other hand do not have a throttle. They are controlled solely by the amount of fuel injected into the cylinders. Not having a throttle valve, there is no restriction to the engine provide a vaccum when deccellerating, and hence, no engine braking. On large trucks (or lorries) the diesel engines will often have installed a valve in the exhaust system to provide the same effect, or they will have a compression release built into the valve train to do the same thing (often referred to as a "Jake Brake" as they were originally manufactured by the Jacobs company).
Some vehicles dont have EGR Valve... I have a 90 Caravan, same engine as yours, basically the same thing as what you have and it has the EGR valve, then again, same engine in my 92 Dodge Spirit and it has no EGR Valve... the EGR is just mainly an emissions thing to help keep down on air polution. If yours did have the EGR Valve, they are really easy to spot, its on the left of the throttle body and the EGR Valve even says EGR right on top of it, so if you do have the valve you will know it very easily with or without any book or diagrams.
I got the same problem. Replace the cutoff valve for $100 for parts.
No, BIG changes. 2005 is single coil based ignition timing. 2008 is 4 individual coil-on-plug setups. 2005 has a normal throttle body and intake timing system 2008 has a timed intake valve system. and that's just the 2.2L and the ones I can think of off the top of my head.
I am not positive the 04 is the same as the 03, but on my 03, the EGR valve is located directly underneath the throttle body in the back. It is difficult to get to unless you remove the throttle body and intake collector tube as a unit.
No, the knock sensor is not the same as a throttle position sensor. The knock sensor is used to determine if the engine is knocking caused by too much spark advance for the octane rating of the fuel being used. The throttle position sensor tells the engine computer what the position the throttle valve is in to determine gasoline flow .
it could be the bypass air valve, or it can be the large hose that conects to the pcv valve. check the hose all the way to the rear of the engine where it hooks up to it and behind it under the throttle body. make sure they are not cracked. if they are replace them. i had a 1994 crown vic and had the same problem at stop lights. i took it to my mechanix and found out it was those two things.
