I have a Mustang 4.6 V8 2005 that have some problem with the fuel meter. Twice in short time it just went down to zip zero without reason. At the same time it display some trouble in the information panel and the Service Engine Soon start to light. After a while though, the fuel meter goes back to normal. The problem is that last time it happend, the S E S want shut down. Anyone got any trick to fix this?
