CEL's with 2g emissions removal

[Weapon-X]

Ok guys I searched and read and searched and read.

I fully understand the emissions system, its components and its duties/purposes.

My question here is simple............... As long as I keep all solenoids and electrical connections, and sensors intact, Will I through CEL's on my 99 turbo by just removing the vacuum lines and charcoal canister? I will be keeping the EGR valve, but I will be using a block-off plate.

I dont see why a CEL would arise but I may be missing something...............

I'm not using DSM Link so thats not an option for dis-regarding certain codes.

I'm not looking for any gains with the removal process. I'm doing it for simplicity's sake. I just cant stand the array of possible leaks and oddball problems associated with keeping the system intact.

I dont need any diagrams or anything like that. Just answers to the above question concerning the CEL's if there will be any.

Thanks for any and all help.

To the best of my knowledge, DSMLink is the only way not to throw a CEL for the EVAP system, when it is not intact.

As far as EGR, if you leave only the solenoid plugged in, you should be fine.

Anyone else have any input here. I'm curious as to why I will get a CEL with the removal of the EVAP. system if all solenoids are still intact and functioning.

Is it because of the nature of having vacuum on certain ports of the system at certain times?

Basically all electrical connections will remain intact for me, I'm just not gonna have them connected to the hard parts and lines of the system cause they will be removed.

Every car seems to be a bit different, but before I ran DSMLink I had all the solenoids still plugged in with EGR blocked off and all the others capped. I never had the CEL come on until I unplugged one.

Thanks for your reply. Out of curiousity, how long did you run your car like that? Were you a daily driver or weekend/good weather set-up only?

I'll have a 95 Eprom ECU so hopefully its not quite as finicky or quick to throw out a CEL for something. I have heard that some of the later 2g ECU's are a little bit quicker to throw on the idiot lamp over such things as emission control items and what not.

Jeff O. will be doing a Eprom chip for me................. I'm wondering if he has any provisions or line codes he can add to deter the ECU from throwing a CEL do to emission related/deleted items.

Thanks again for any insight fellas.

I probably ran like that for over a year daily driving year round with no CELs for emissions or anything related.

Thats good to know im doin the same thing to my car right now..

Thanks, I was hoping to hear that.

I am running with the EGR block-off plate and the solenoid plugged in on my 99 GST. No matter what I do I can't keep from throwing an "EGR Flow Malfunction." Emissions inspection is coming up and I would really appreciate any advice you guys might have. Thanks a lot.

I capped the three nipples on the TB and left all the sensors plugged in, I always get a EGR malfunction code. P0400 i believe, plugged the vacuum lines back in, no more CEL!
