Car Stalling
Re: Car Stalling
Bad Optis tend to be hard to troubleshoot! Rule out the EGR first! Bypass it by removing the two screws that are attached to the back of the manifold and place a piece of metal cut out to fit the hole and retighten this to see if this helps. If it does it is the EGR valve. Just because you have a lt1 with a 112,000 miles on it does not mean the opti is bad. Good Luck on your car!
