Question about 1989 Chevrolet G10
The egr valve is faulty on my chevy 305 motor. i have been told i can just cap it off. so where do i cap the vacuum line so that the motor will not backfire threw the throttle body?
Although bypassing is not a good idea,If you are doing this,You just cap the vacuum line with a small bolt,Cap the exhaust tube with a threaded cap.then you will need to reset or remap the ecm and ****** the timing about 2 degrees.
The ecm will need to re learn to adjust the proper fuel/air mixture
and you may never get the check engine light to go off.
Also you will notice a decrease in MPG
If I were you,I would just put a new egr in.(They are cheap)
