YES, A scoot may come with up to 3 emission devices a PAIR. EGR and a EVAP system and the scoot will work with all 3 disconnected. But here is the thing any one of the systems may CAUSE problems if they are on and NOT operating properly.
I have the same problem with my truck, It notorious... You have a stuck EGR valve.. Replace the EGR valve and it should work fine.
take the EGR valve off and spray carb cleaner in the egr valve and in the port. This will some times work as it gets plugged up
http://www.lcengineering.com this place sells egr block plates for your pickup. They work great I have them on my truck. Off road use only ;-)
egr stands for exhaust gas return. it sends the unburt fuel back into the system to be reused. generally you get a gas smell and it will make the check engine light on
!987 Bronco II had egr system, but 88's dont have egr system. I own and 88 and a manual and it states this
EGR system failure. The EGR valve has failed.
It does NOT come equipped with an EGR system.
I's a problem with the EGR system and or the EGR solenoid.
the vortec 4200 doesnt have an EGR system
Worn piston rings and or clogged EGR system and or failed EGR valve
The Chevy 4.3 egr system is important to the proper operation of the engine. A clogged egr can cause rough idle or low fuel economy, among other things.
EGR stands for Exhaust Gas Recirculation. The purpose of the EGR system is to lower the amount of oxides of nitrogen the engine produces. The parts of the system are the vacuum actuated EGR control valve, the vacuum switching valve, and the EGR vacuum modulator assembly.
