Need some serious Help,gonna break something

I am working on my brothers 92 lincoln town car.We were having alot of problems the the alt./charging system.We figured it out.Then the battery was draining,found the draw and fixed it.the car was sitting for about a month while we got time to fix it.SO today i changed the oil,oil filter,plugs,air cleaner,and added some fuel injector cleaner.Well it started right up and we got it to the gas station and put some air in the tires and as we were leaving it was like stalling alittle,not transmission stalling like it almost was getting starved of fuel.then we got it to the next gas station and now it keeps dieing when put in gear,any gear,SO i had to keep the gas down a bit while putting it in gear or coming up to stop signs to stop it from dieing.I am going to check the fuel filter tommarow but its only about a year old.What else could be making it die like that?If it were an older car/non fuel injected with computers I could figure it out,just not that familiar with newer cars.Could it be some kind of sensor?

IAC (Idle Air Control)... Up on top of the intake has a 2 wire plug and 2-10mm headed bolts that hold it in place... R&R it (go to the Ford dealer for the correct replacement)...

I have had similar issues with both of my T-Birds (94-97)
Both of em needed the MASS airflow sensor replaced
(the 97 died in rush hour traffic--on the freeway)

Also----a sticky EGR valve could do the same thing (sticking open)

Bryan


Thinking back----MASS Sensor may have failed on both cars after charging issues with both

Alt diode with the 94
10yr old batt on the 97

Does it run OK except it won't idle? If it is an idle problem only, then IAC is a good place to start.

Got a check engine light? Steady or blinking?

there are two elements.one visable another in the tube.the one in the tube is to be cleaned.I spray into the tube with a little tube.NOT carb cleaner!AIR INTAKE CLEANER or motor vac chemical.also clean the visable one.it's really hard to diagnose through Email,so before changing parts I would have it check.I would clean the IAC frist. Also look for vacume leaks

Alright i found the IAC and cleaned it,it was pretty nasty,I cleaned the MAS,I also cleaned that valve with the spungy thing in it.It doesnt die anymore but still runs like crap.When the engine is cold it doesnt do it.After it gets full warmed up it sputters when you accelerate from a dead stop,also while going a steady speed it does it.The fuel filter was kinda bad so i replaced it.What else could it be?It feels like its getting starved of gas at certain times.any help is appreciated

Just for good measure, you should also replace the fuel filter and either dump some HEET into the tank or siphon out the old gas and replace it. Sounds like you might have some water in the tank from sitting.
