2002 P5 smoking, burning oil, rough idle...

I just got a 2002 Protege5 2.0L 5-Speed. It is having a rough time staying at idle. In the morning, when the engine is cold, It smokes VERY bad. The smoking dies down when the car warms up but still smokes lightly. It is using oil very badly. The check engine light came on and the OBDII says ''EGR flow insufficent''. Ive cleared the code, but it came back the same day. When accelerating, during 2-5k RPM the car stumbles and hesitates VERY badly. Will the EGR valve cause ALL these problems? Or could the DPFE cause this?

It also has STI coilpacks on it... is this good for it??

All opinions and ideas of what could be wrong are appreciated.

Thanks guys!

The EGR will cause a real bad idle if its dirty. I'm not sure what a DPFE is. A bad PCV valve can cause bad oil consumption as well. Clean the EGR, replace PCV valve and replace the spark plugs at least.
 
It's super easy...it's the 90 degree elbow on top of the valve cover. Remove and replace. If you can blow air through it both ways, it's bad. Any other symptoms that would explain the smoking? Engine noises that are unfamiliar, things like that?
 
The engine sounds normal, no ticking..knocking etc. Ive only had the car about 3 days so i havent had time to change the oil, So im not sure what weight is in it right now. The guy i got it from from was bragging about the STI coilpacks on it (acting like it was a performance upgrade).. im wondering it they have something to do with the sputter going throigh 2-5k RPM. The engine only has 84K miles on it. The car is VERY clean and its awesome except for the horrible oil consumption. Im hoping that after cleaning the EGR, Replacing the PCV valve and plugs that the car will run smoke free and smooth.
 
Not to be an ass, but didn't you notice any of these problems before you bought the car? At the very least you should've taken it in to a mechanic for a thorough inspection. I'm guessing if he put "Performance" coilpacks on the car, then he ran the engine pretty hard (not necessarily because he could so much as he thought he could), so it may have some abnormal wear and tear on the inside.
 
I'm goin with dirty egr = bad idle. Maybe on the PCV = oil burning. It's a cheap test but my bet is that the valve seals are toast = bad smoking/oil consumption.

My old P5 went through 3 oil sending units(all leaked bad) and 1 bad pcv valve. The oil consumption went way down to below .5 qrt per 3k miles were it was going through 1.5qrt every 3k with around 160k on the clock after I replaced the oil sending unit and pcv valve. Eithe way both items around cheap.

It could be the seals but I doubt it with less then 100k on it. I have been known to be wrong before.
 
Oh yeah, forgot about that one but didn't see where OP said anything about puddles or dripping which is what would happen if all that was going out the oil pressure sending unit right? I was going off the smoking references. Guess he'll tell us eventually what was happening.

I didn't know mine was leaking tell I went to remove my oil filter. I had one hell of a time getting that damn oil filter off without a wrench. However the bad pcv valve could get stuck open and gum up the egr valve.


Edit: I'm still woundering what the hell a DPFE is.
 
I traded even for my 95' integra.. come on now lol. Idc how bad its smokin... integra with 150k miles vs. 02' protege.. ;) DPFE - differental pressure feedback EGR.
 
well cleaned the egr (which was filthy) and tested the pvc and it is still good. The car idled alot better for about 10mins then went back to the same rough idle and dying crap. At times the car smokes so bad you cant even see what is behind me in my rearview lol. Im usuing a 1qt. every 20miles. It is horrible.. how hard are valve seals to put in? and is this more than likely the problem?
 
lol 1 quart every 20 miles...your rings are gone buddy...you need the bottom end rebuilt asap..your just gonna **** it up more by driving it...atleast now you have a block to work with

Sounds like you have major issues right their man.... I would suggest looking into new motor soon.
 
I agree with the above posters. It sounds like your piston rings are shot to hell man. Again, that's why I always suggest taking a used car to a mechanic before you buy it. A 30 second compression test would've caught this easily.
