oh yes, i just had my egr tubes cleaned today, and boy am i glad i had it done. my cars acceleration is back to normal, and i can definitely feel the difference. 195 bucks at the stealership, but well worth it

 

is this possible to do yourself?

 

eckohb, did you noticed a big time difference in performance ? they told me mine was completely plugged and that if they cleaned it out i would lose HP ? anyone heard of this ?

 

Eh, sort of. The egr system is only active during partial throttle, especially cruising. At that time it injects spent exhaust gases into the intake. This results in lower combustion chamber temperatures and a resulting drop in NOX formation. The exhaust gases also replace fuel/air that would otherwise make power, but since it isn't active at WOT, who cares?

On the other hand, if your egr valve won't completely shut because of carbon buildup, then you get exhaust gases going into the intake at all times. This can cause poor idling, driveability and a loss of partial throttle and WOT acceleration.

 

+ ****ty fuel economy.

 

so is there a write up anywhere or how-to to do this ourselves? or is a job like this extremely hard for a weekend mechanic?

 

i suppose its possible to do yourself. I could have tried it, but Im too busy with school and work, and have no time. http://forums.maxima.org/showthread.php?t=298383 theres a thread about it. maybe that can help you out
