run as little as possible and keep off the road and heavy loads until problem/failure found.
check the base timing, can only be set reliably with SPOUT removed, if can't see the timing marks or marker point gone, then loosen the dist. lock bolt slightly, mark an alignment point on engine parts near dist. with one cap mark point and use that as a reference...slip the dist about 10d one direction and tighten lock bolt. start and test engine, if worse, move dist. 10d to the other side of cap mark and try again. keep setting back until no pinging noticed then set back another 2-5 degrees, take out and test on a steep hill load, want no audible pinging under any circumstances. don't forget to plug back in the SPOUT. make permanent marks on dist. shaft base and mounting for future reference.
the old school way we used to set up engine timing without a timing light and to match all the old engine variations block to block, driving styles and fuel variations.
ahh ok. hopefully the timing should help. if not....probably as mentioned earlier it might be carbon build-up, even though the 3.0 isn't known for carbon problems(from what I've heard here). a decarboning wouldn't hurt. I know you posted that you had seafoamed it...maybe try the water method.
Ray,
well you know it's getting your good care now...someone before was not taking care of it..putting in the wrong plugs...you will probably find more minor prior owner caused problems...but these Aeros are tough...Ford tough....
Ya that's true..
A little history about the car... I bouht it from my fishing partner after he crashed it into the creek at 70mph.
The car never got regular oil change evert 6000 miles or so, and I had to do it for him.
He also put some smelts into the PS pump res. so the fluid will be thicker so it wouldn't leak
So the first week that i had the car, I had to rebuild the front end, and flush all fluids (Boy was the brake fluid black).
that's one TOUGH Aerostar...I fish but usually restrain myself and don't go crashing into the stream...may be a new steelhead technique for this winter...drive over them

or back in with the tailgate open....let her fill up then...."home james"it's dinnertime.
just remember to bring a twelver of aerobeer to work up courage to go swimming with the old girl.(designated driver recommended)
Checking the timing on a 3.0 with the marks on the passenger side is not imposible, in fact, its really not even difficult. Take some chalk and rub it into the marks on the damper. This improves visibility. Now, take your timing light and point it towards the pointer. You may have to push the upper radiator hose over slighty, as you do in mine, but if you do, you will quickly find a position at whish you can both get the light at the pointer and see it clearly.
How well do the timing chain in these cars hold up?
Could it be that mine is worn out? It has 216,000km on it.
That is approaching the end of chain life where you start to get some slack. After checking the timming and seeing it off. I would start there. Fairly cheap (around $100 for chain and gears,) but you will have to do some major bending to replace with engine in.
