Re: EGR Valve blocked off. Problem?
Short answer - No, the EGR is not a factor in your problem. Look elswhere. For a bit of schoolin' read on:
The EGR introduces "dead air"
(air not charged with alot of oxygen and what should be zero fuel since it is now officially exhaust)
from your exhaust manifold into the intake manifold.
What this does is:
1. Cause your engine to run cooler since you are not giving the cylinder the entire shot of air and fuel.
(This causes a dramatic drop in certain emmissions but at the cost of...)
2. Loss of power.
(It effectively makes your engine smaller since the cylinder size can not be completely utilized due to the "dead air" introduced into the cylinders.)
When the throttle is open more than a little, the EGR valve begins to introduce the "dead air". Personaly, I think that is crap. Because if I am not getting the power I desire at half open throttle, I open the throttle more until I do. In other words, I am burning the exact same amount of fuel to achieve the desired performance. F- the smog nazzis.
