Guys,
I failed emissions again today for Nox being high.
Tuning, plus a new cat conv, and a JB welded nipple on
the EGR solenoid and went to retest. My EGR valve was
replaced before I got the car.
My brother felt vacuum on the hose to the EGR, but I
want to put a gauge on it and drive it around now.
When I applied vacuum to the EGR at idle, the engine stumbled. I want to take the EGR off and check the passages first.
I lowered the NOX from 3000 to 2000, but it needs to
be 1000 to pass. I passed HC though this time...yeah!
If everything checks out OK, then my next recourse is
to replace the EGR valve.
Could someone with an original EGR on their car
provide me with the OEM number on top of the EGR?
Just pop the black plastic cover off and there should
be info on top. The number should start with a
1708xxxx or 1711xxxx.
Thanks in advance,
James "No pass go" Wicmandy
