I had a friend fail inspection on her car(95 camaro), specifically the NO part and the shops replaced the EGR valve(Exhaust Gas Recirculation).
I had never heard of this before so I researched it and found that it acutally takes exhaust gasses and re-inserts them into the cylinders to lower the burning temperature and help the NO pass through the system unburned and prevent it from picking up other atoms and becoming smog...basically.
The science I have may be a little off, but the principle is the same.
Well I got to thinking about where the TJ EGR valve is....and I CAN'T find it on my jeep or in the FSM for that matter as well.
DO TJ's have an EGR valve? If so where...and if not, what do we use in place of the EGR.
'97 TJ SE...yeah yeah I know, it's a 4 banger.
