Engine Performance problem
1997 Ford Aerostar 4 cyl Two Wheel Drive Automatic 200k miles
97 Ford Aerostar 3.0L 200k miles
Van has started to stall out & die when put in gear. It starts and idles fine until it's put in gear, then stalls out. Upon restarting (which takes several-many tries) it runs rough for a minute after restarting, skipping & smoking a bit, then smooths out and idles fine. When put in gear it dies again. This started on an intermittent basis but has become more often. Since this started, I've noticed(maybe because I'm paying more attention) that when you slow down the downshift seems more noticeable. I thought it may be a fuel injector problem or water in gasoline so I used injector cleaner/fuel treatment but haven't road tested it much so as not to get stranded! LOL I have also changed oil & air filters but have no idea where the fuel filter may be, also looked for obvious vacumn leaks but I did not see any.
If anyone has any advice or suggestions they would be greatly appreciated !
