    need to know size of engine. but the principal is the same for removal. most egr valves have 2 bolts holding it down, remove the wireing, then remove the other hoses, unbolt egr then remove from vehicle.

Just replaced EGR valve- had code P0404. It's

First question, did you clean the port or passage out or the cyl head where the valve mounts to, when the valve was taken off of the engine? 2nd question, did you replace the Vacuum transducer ( little black round valve, with a vacuum hose fitting) and the valve assy? After these items have been replaced, it usually needs to have the PCM (powertrain control module) reset with a scanner of some type.

My 2006 dodge caravan is throwing the code po404, what does this mean and how can i fix it?

p0404 is an EGR valve problem.
Most are vacuum operated and is set off when the position doesnt match the expected one set by the PCM... however, depending on your location - the van may be equipped with an electrically actuated one that will need to be re-programmed at the dealership.

P0404 err code and it feels like engine serges 45 to 55 mph

Check your EGR valve hose for leaks/cracks etc, remove wiring connector & clean all contacts. Remove battery terminals before you start, but make sure you don't have to recode your anti-theft, or code your stereo, without proper info ready at hand. If your not sure, leave them on, but make sure key is off. Try again now, and see if code returns, if it does, get a new gasket for EGR valve, remove it & clean it thoroughly with throttle body spray cleaner, and re-install. It should be located close to throttle body, with 2 bolts attaching it to intake manifold. Near TP sensor & IAC motor. Try again, but see if you can get codes erased prior to, or immediately after, and see what happens.
