egr could be stuck open. try to take it out and clean it

 

[mymp5]

on the p5s are they hard to get too

 

[Tiger Brand]

it's pretty tight. find a mini socket set.

 

[mymp5]

that would be the first place you would look where would be the second do you think it could be the fuel filter cuz it seems to be worse when it is low on fuel

 

[bazooka joe]

try cleaning the IAC too, it's easy to get to and it was the source of my bad idle!!

 

[mymp5]

there really isn't a replaceable fuel filter on the protege/protege5. i mean, you can rip out the gas tank to clean/replace the little filter on it, but odds are that it won't be the problem.

^^ you don't have to rip out the tank.. just the fuel pump.

yeah but there isn't a filter on the fuel pump. the filter (or sock) is inside the gas tank (which in most all cases will never have to be replaced.)

off the subject but your P5, tiger looks bad...im jealous

 

[mymp5]

You can just flip the back seats and there is an access patch right there.

It could be a vaccuum leak. check all the hoses and PCV valve.
Run a can of seafoam in it too.

 

[P-Funk!]

Check everything else first - before pulling the fuel pump - filter 'sock' is attached to it.

Very Rarely is it the fuel filter or pump for our cars ('whew'!)

Go check the gaps on your plugs, maybe 1 of them closed in.

i am running the NGK Spark Plug: Plug No. BKR5EIX-11
Iridium IX Plug;

do you think the plug got hot enough to make the contact shorter what kind of plugs do you all recommend to run that work the best

This is a good thread to read:

Hope it helps.

 

[Cellerator]

is it still idling rough right now? I think it may be the vtcs screws that possibly got loose and damaged one or more of your plugs or just closed the gap up real nicely therefore you'll need a new sparkplug but check before doing anything else.

not as bad but it seems to be worse the less gas is in the tank i do not go below 1/4 tank but that is when i seems to do it worse thats why i though of the filter but since it is internal i can call that one out the window. i might just call the dealer and order those plugs and see how they work. i really appreicate the help
