I am trying to solve my random misfire when warm still and I got a egr code when I ran KOER. If I take the vacuum line off and cap it off and run the car would that be alright or make and difference?
Also any chance someone could walk me though deleting the emissions junk? I plan on taking off everything but the air pump, until I get a shorter belt. What can I take off and what do I have to cap?

Just look at the pump and follow everything that goes off of it.

There should be something going to your intake, something going to your mid pipe, some thing going to charcoal canister, and I don't know what else.

If you unhook the egr vac line the computer will delete its function.

what code was it??? and when does it occur when warm?? cruise, accel, decel or under load only??

It was code 33 opening not detected. The miss seems to be gone under hard accel and is most noticeable at idle. It also never seems to be the same cylinder and is not constant like there is no constant rhythm to the miss. The car seems quite boggy under load as well.
I am not sure if this is related or not but when the car has been driven and then turned off when restarted if you don't give it some gas it will cut out. The weird thing is if I don't give it throttle and let it die when i restart it again right away it will start and idle fine.

You say that it does run propperly from time to time?

Very, very rarely when warm, but when cold it usually runs as good as I expect it to.

Not to hijack, but If you plug the vac line that goes to the EGR with a bolt or something and plug the hole in the intake will it be fine? I just pulled mine off, and i was wondering if there was more to it then that.



What can you use to plug that hole thats left in the intake?
