Hello!
So, I'm new to the forum (and new to Ford's if I'm honest), but I just bought this wicked cool Aerostar and I really want to keep it going. Here's what I need help with.
First issue, it seems to idle kind of rough. Not a high idle, and never so bad that it dies, but it's definitely not smooth. Once it's running and you give it any gas it smooths out and is fine. No seeming power loss on acceleration. As far as I can tell MPG is still good (got about 21 on my 600 mi. road trip home after getting it). So far I've changed the PCV Valve and the two hoses to it, cleaned out the IAC valve and MAF sensor. A friend and I pulled a spark plug and it looked decent, so I don't know that that's the issue. The only other thing I can say is that when we were checking the MAF, unplugging it would change the idle for maybe 10 seconds and it sounded good before reverting back to a rough idle. Same thing plugging it back in, good for a short bit and then back to rough. Does this indicate a MAF problem?
Starting: First star after not having been run for a while is always great. First start in the morning it starts right up no problem. After having been run for a while and it's hot, sometimes it will crank for a long time before starting up or not crank at all. I turn the key, all the dash lights come on, but nothing, just like a click. Turn the key right after that and it sometimes starts. A starter? Solenoid?
This forum has already helped so much. Anything else would be most appreciated. Thanks everyone, Chris.
