- '94 AWD Aerostar XL
I'm only getting 13 mpg on mid grade gas. Previous '94 AWD got 24 or so reliably. Starts easily hot or cold, and has lots of power. I suspect one or a combination of the following: open thermostat (coolant only getting up to about 144 degrees on freeway with A/C on), coolant temp sensor, oxygen sensor. Wondering if the 130 degree switch from closed loop to open loop is at exactly 130 degrees, or does it vary? I picked up a Motorcraft 195 degree one that I'll likely put in tomorrow, then assuming it warms it up to snuff, I'll check the resistance on the coolant temp sensor. Hopefully, that will do the trick, but if not I'll look at oxygen sensor(s?). Any thoughts or suggestions are welcome. I like this van a lot, and I'll like it a lot more once it lightens up on the gas consumption. Thanks for any insight you folks can offer.
