I have a '92 Marquis with the strangest problem I've ever encountered. The car starts up fine, but idles for a few moments, then dies. It will start right back up again. The odd this is that it doesn't die when the MAF is disconnected. I replaced the MAF and it still does the same thing.
It's recently started making a hissing sound. The noise is coming from the rear of the engine on the driver's side. It sounds like it's coming from the throttle body, but I pulled that off, and put a new seal and RTV on it. Any suggestions? I'm going to pull the intake manifold off this weekend, and would like to clear this problem at the same time. I'm also going to replace the O-rings on the fuel injectors.
This car has the 4.6 Liter engine. I don't have all the other details on it right in front of me, but will post them here shortly.
