This is a follow up to the BIG BANG thread where the pop off valve was blown to pieces.
I installed a new pop off valve in the existing airbox hoping it would be a quick fix. The car "starts" but doesn't "run". If this was a carbed car I would say it is running on the prime. Maybe the cold start valve is giving it gas to fire then stops? Is this fuel delivery issue (maybe it lead to a lean backfire) or blown airbox? I am hesitant to pull all the CIS stuff off to get to the airbox as I know I will be in over my head. I have read a few 911 threads on removing the airbox and it is something I have never done. How do you get to the runners under the box (4 -5 6)? https://www.youtube.com/watch?v=vaA44-K30QA Engine is a 2.7L from a 1976 911S Thanks in advance! |
