Hey ive been trying to fix a egr problem.i forget the code(limited flow) but the guy at Auto Zone said to clean the egr valve and look for vac leaks before i bought a new one.well i think i have replaced every vac line that looked bad ,my worst ones going to the fuel canister.
As of now my car runs very smooth.but the light is still on.

My question is if i fixed the problem that was causing the cel to come on, will it turn it self off right away(telling me i fixed it) or do i need to clear the codes in order for it to shut off.and wait to see if it comes back on again.

You need to clear the codes. Unhook your battery for like 20, 25 minutes and then hook it back up. Or, any shop with the ODBII connector and a scanner can do it, think they'll charge though ?

Why unhook the battery when pulling fuse #15 under the hood does the exact same thing?

Since he is a newbie; the Fuse 15 trick should be explained in more detail.

Remove fuse 15

Attempt to start the car (it won't)

Put the fuse back in.

Computer has been reset. CEL will be off

I agree, I should have explained that! Now he knows, so much easier than removing battery cables though!

Thanks for the tip on resetting the cel and clearing the codes,much easyer than doing the battery which i knew.

I was hoping that the car would know if a problem was fixed and turn the cel off on its own.then i clear the codes.kinda like when you have the starting of a bad o2 and the lights only on from time to time.

Actually, I believe the CEL will go off, after so many drive cylcles without the problem being detected.

One last question.In getting codes pulled,from autozone.i was givin the list of the 3 things that could be causing the code(which i forget(low egr flow) but was told check the vac lines i'm pretty sure i have replaced them all (some were split)clean the egr valve(and i did)check my plugs(new)

i was told if i still had the problem then it was indeed the egr or the celinoid.now today i stop at a light i could feel it grumbling alittle so i know the CEL will back on
any bets as to which piece would go bad?i was told there was not seprate codes for the egr and celinoid,any truth to that?

with my luck i would buy the wrong one.but both might not be a bad idea.

Don't have the book in front of me, so don't take this as gospel.

1. unplug IAC
2. disconnect vac line off the EGR and plug it (a golf tee works)
3. hook up an external vac source (i just used a long piece of same size vac hose and my mouth)
4. pull a vacum on the EGR

If engine idle changes; EGR good.
If not, bang the heck out of the EGR valve with a screwdriver handle. Repeat check.

If still fails, or can't pull a vac on it (diaphram in valve broke), EGR bad.

This is pretty close to the haynes manual, hope it helps
