Disconnected EGR valve... Engine runs great now.
 

Out of curiosity today I disconnected the EGR valve on my '86 Prelude 1.8
dual carb w/ 5 speed. My good ness what a difference it made. Drivability
when the engine is cold is great, I don't have to rev it out the wazoo to
keep it from shuddering and bucking anymore. Also, I immediately noticed a
huge increase in power. The thing loves to rev now, I step on the gas and it
really winds up, and throttle response is so crisp and quick. Before it
would accelerate and rev nicely (though not as good as it does now) until a
certain point of throttle opening when presumably the EGR valve would really
start to open up. The car would then fall flat on it's face and bog down, if
I backed off the throttle it would perk back up. Now I can slam the throttle
down and the thing winds up and keep going.

I guess what I'm getting at is that it feels like a whole new car. I would
prefer to have the EGR valve connected to reduce emissions, but not unless
the car will run right with it connected. I think I'm going to try taking it
off and cleaning it out to see if that helps at all. If not then I'll leave
it as it is now. So does it sound like the EGR is working properly? It
definitely is 'working' as I can tell a huge difference when it's connected.
The car will now push you back into the seat if you get on it, I love the
performance. Also I expect mileage to increase, as I've heard others say
that when their EGR valve broke or they disabled it their mileage increased
a good bit. I would think the increase in mileage from a better running
engine would help offset the increased pollution. Anyway, let me know what
you guys think about keeping the EGR disabled, and if there is any way to
get the engine running well with it connected.

EGR needs some housekeeping, probably

Reducing emissions is not all it does. It also reduces upper cylinder
temperatures. By running for extended time may cause heat damage...

Re: Disconnected EGR valve... Engine runs great now.
 

Are larger jets for the carburetors available? That ought to counteract any
leaning out of the mixture that would result in higher cylinder
temperatures. Perhaps going to a 180* thermostat (195* now) would also help
counteract that?
