Emmisions removal + STANDARD ECU ??

hi guys,,,right ive removed all my emmisions crap,,, air pump, swithching valve, all pipes,,, the 2 solenoids on the rack that are no longer needed and the solenoid vacuume pipes have been removed or capped..
I know that running on the standard ECU will throw up some error codes for the stuff that has been unplugged and removed,,,, but what about running and driving the car,, (will probably have a lumpy idle due to the air pump removal and O2 sensor feed back been misread),,, but what about running and driving the car,, im presuming none of the solenoids and sensors removed will put the car into limp mode and the only thing that should really be affected is the idle,,, can someone who has done the emmisions removal give me some feed back please?
thanks

The limp mode will make the car very slow .If you wire in resistors in the harness to replace the solenoids then the ECU will not know the difference ,and not go to limp mode

It will go into limp mode. The EGR will do it for sure, happened when mine was all carboned up. I would also listen to Garco he is quit wise when it comes to the FD, and has gave me a great deal of knowlage in the past.

In US models, a missing (or malfunctioning) EGR should only throw a code. It will only throw a code on '93 California and all '94 models (models with the electronic sensor). This might only be for US models. There's a neat relay trick for those with these models.

If the OMP fails, the car will go into limp mode? Really? I didn't know that.
