Hello all
My dad has a 1997 ford Aerostar... with the 4.0L OHV engine we are all familiar with. The problem is that when it's idling, every so often the idle just jumps by about 300 rpm and then comes back down, and also sometimes it drops by 300 rpm or so and comes back up. It's very sudden and erratic in how it does it. I cleaned the IAC, which was pretty dirty, and it went away for a week or so. I was thinking possibly the MAF needs cleaning as well? Any ideas? thanks
