Question about 1996 Ford Crown Victoria
Bought car w/ 100k miles.did basic tune up. at 135k fouled plugs so bad did not want to start. replaced coil packs,wires,and plugs again. ran great for bout a week. now wants to stall again. check engine lite said both banks runnin lean. friend had similar trouble said he found vacuum leak in a hose that runs from intake tube to back side of throttle body. found no leaks. any ideas on where to go from here? thanks for your help.
The upper intake gaskets leak on these engines, here is how to check this, get a can of carb spray, spray all around the engine top, esp around the upper intake/plenum gasket area, if the engine RPM changes you have a leak.
