Test for EGR
My 96 Bonnie set a code P1406. It'* the 3.8L. Wife went by Autozone and had the code pulled. Print out says the EGR pintle position was 10% of the expected position.
Failed EGR valve
Open or short circuit condition
Is there a way to test the EGR or does it need cleaned (stuck in one position)?
The car has been acting up for some time now. When the wife leaves work and goes a short distance and comes to a stop light, the rpm drops off, runs rough, volt guage drops way down.
Don't know if it is related to the EGR code or not.
Thanks for any help.
