I did the egr delete and covered the hole with a plate good and tight. I even waited till the next morning to start it up. Sprayed it with carb cleaner and no leaks. But when it gets warm after like 3 to 5 minutes later it runs erratic and automatically shuts off. If you can help it would be very appreciated. Someone is going to look at buying the car for $1600 later and I have to get it running right. I can take a video of it running wierd if needed. PLEASE HELP!!!!!
