I remover my EGR for my HO intake swap. Now fan fan runs all the time. What can i do to stop this?
2nd Place is the first loser
clear the code each time it sets
use a 99 pcm if you have a 97-98
try the egr simulator
yep, thats what happens. With no EGR your cars fan will do that. Does it on mine too.

As '97cavie said, use a '99 ECU. You'll have to switch to the '99+ knock and run the wires to the correct pinouts on the new ECU.

How much is an ECU? Sounds like a PITA.

Why not just run a fan switch via a temp sensor? Then you tell it when to come on and go off.
i clear the code each time. runs great., i have the gm s/c though on my 96.
i tried the egr simulator and it ran like crap. so have others.
damn EGR. damn it damn it damn it.
You just need to make the EGR fit with the manifold. The 99 ecu swap will be alot of work. The EGR sim doesnt work. So i think the best bet is to get the EGR to fit with the manifold in place.

to shut off my fan i went under the hood and took out the cooling fan fuse i mean it never turns on anyway if need be pull over and put fuse back in but thats how i fixed it

Have you done the swap? Don't talk like you know something, if you haven't done it. This site is full of people more willing to talk then try.

No i have not done the swap, please tell me what is all involved.
But since you didnt seem to understand what i was saying, all i was saying is that just fitting the EGR to the car with the HO manifold swap would probably be the easiest thing. And this is something i HAVE done.

Don't speculate, it just spreads information which may be wrong; especially for a newb like the original author.
The '99 ECU swap involves running two wires from a new knock sensor to unused pins on the ECU wiring harness. Took me 15 minutes maximum. You can have both the stock (1 wire) and '99 (2 wire) sensors hooked up until the ECU is reflashed since the pins are used.

whats EGR? 
EGR stands for Exhaust Gas Recirculation, wich basicaly means, some of the engines exhaust is sent to the intake manifold to help keep cylinder temps down, thus improving emissions
Some times the best way to get that tailgater off your but is to light a fart.
