Default Egr Delete Problems

I just deleted my EGR system on my 98 z and it seems to not get up and go when i punch it like i used to. It seems to run just fine except for idling just a hair higher than it used to but drives fine I put the block off plate going to the headers and on the head and also the plate I put on top of the intake to block that hole so do I need to have the car tuned and have the codes removed or what could be wrong. Thanks,Brandon

Where possibly though? I didnt put an expansion plug in the hole on the intake. Could that be it? I thought that was what the plate was for but I could be wrong so someone help me because their was no leaks until I took the egr off so I am guessing I need the Expansion plug after all for the intake.someone tell me whats wrong oh and I drove it a minute ago and let it set and idle and now it was idling up and back down every 5 seconds or so

Definitely...there is only one bolt to hold it down..so I don't think it would have enough pressure to keep the plate down on all sides?

You don't need a plate or whatever he is using.

Just go to AutoZone or other local parts store and find a rubber expansion plug...I can't remember what size it is though...use a ruler or something to measure the whole..then get a plug that expands to bigger. If you get the wrong one, just take it back and exchange for a different size?

Yeah, get the 1 3/4" expansion plug, just make sure to clean the walls of the hole to free it of oil residue, and clean it with some rubbing alcohol to get it nice and dry.

I would definetly recommend a Tune if you are gonna completely delete it... plus the car will drive better and not throw any codes. My 10 cents
