So I got the codes today. He charges $20CAN (almost the same as US) :)
P1125 Throttle Position Sensor Intermittent
P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1
The mechanic said he didn't know which of the 4 O2 sensors it is. One was easy to change. I don't know which. I just got a quote from Ford, $170-190 depending which one. Sounds a lot to me.
The TPS was $107. Sounds good.
The Low Coolant level indicator he said had to do with the windshield fluid level sensor ?!?! But only $25.
That's as far as I got today.I had no code for that.
