I have a 93 Mercury villager. (Aka Nissan Quest). I've had the van a short
time, and pumped some cash into a new timing belt, etc. She starts, and
seems to run fine. But today, when coming back from getting new tires. She
seemed to be starved for gas. Around 35-50 miles an hour. You can press on
the accelerator, and she'll hesitate, almost like she's going to cut out. If
you floor the gas peddle, she kicks down a gear, and seems for a bit.
Turning off overdrive seems to help a little, but when you get to a certain
speed, she starts to act up again. She's had a full tune up (plugs, wires,
cap rotor, fuel/air filter, pcv valve, timing belt/water pump). I've checked
the transmission fluid, and it's not low.Mind you, this doesn't seem to
happen until she's all nice and warm. What type of things should I start
looking at? Any insight would be GREATLY appreciated.
