the EGR shouldnt be open at idle unless the ecm does it.

kinda I took off the part where it plugs into then glued the plunger half way down to make the car think its working






I know but it works great!
If that were the case it wouldn't be flagging that code in reference to the sensor

As soon as the EEC detects an EGR related failure.......... it will delete/bypass its function, the only "issue" of having any EGR code logged, other than code 33.... is that the CEL will turn on. If you have the EVP connected, you could "simulate" a good valve closed signal (which is what the EGR simulators do).... by setting the EVP plunger to output anything between .24 vdc and .67 vdc all the time. This will cause codes 31, 34 and 35 NOT to appear, and the only one that will be logged is 33.

Looks like the cause of your problem lies somewhere else.

without my rigged sensor the car ran poor on first startup, with the sensor plugged in it runs a lot better
