Do I even need this part??
Do I even need this part?? okay, when i did my cam upgrade i had the EGR and AIR system deleted from my computer, well when i pull off my valve covers i find there is a ton of little, what seem to be like carbon crystals in there... since the intake manifold was off there is a sensor on the pass side, its like a 3 inch long sensor, bolts to the manifold, and has 2 vaccum lines running off it, do i even need this? from what i have seen its an EGR purge solenoid which i no longer have, and i shook it out and it was like the movie black diamond, nothing but black crystals shook out... if my EGR is deleted, do i need this sensor???

On the passenger side is the EVAP solenoid (not a sensor). What you are finding is carbon that has been sucked from the canister in the RR wheelwell. It could have only gotten there from incorrect operation.
The EGR solenoid is on the driver's side.
The EGR solenoid is on the driver's side.
so the sensor or bad, or and ive never heard of this but possibly the canister needs servicing? car has 73k miles but runs rich as it has the came and all the bolt ons and really needs a dyno tune... lemme know anything anyone knows on the subject... i dont wanna jump to anything i dont know about...
also if anyone knows the gm part number for this part it would be appreciated, i was told disconnect the line from the canister, and from the fuel line wire loom, have a friend hold it aside and blow it out, what about the canister, does that ever need service?
