does your temp. drop while cruising ? (say on the highway etc) ?
Does the run quite bad in normal everyday driving ?
IF so the thermostat is stuck ope and needs a change.
But otherwise , leave it.
The o2 sensor should give a MIL code on your dash if its bad or totally disconnected
both will make your car run more rich and use more fuel
MIL code?
My thermostat doesnt drop while cruising, it stays about a bar below the middle line (which is normal from what I've read right?)
