THANKS DOUG, I'll pass info on to my mechanic.

Ron - If you need info on the spark plugs as well, it has been covered pretty well here: Question for the duratec owners thread.

coil on plugs..car built in 2012

I am still curious as to why you need new coil on plugs, or is this an upgrade?

As it turned out I didn't.New plugs and adjusting throttle body cables and I was good to go. Still have idle problem at high temp. Thinking it's the air flow sensor. I changed muffler to free flow and it may affect sensor. We'll see next week.

Where is the air flow sensor or intake air temperature sensor?

If the intake air temp sensor is mounted on the air cleaner backing plate without some sort of insulation, it will get hot and confuse the ECU with incorrect temp readings.

Can you read the sensor temperature from the ECU / programming software?

sorry for late reply. I forget to come back to the forum. The oxygen sensor screws in the exhaust pike just before muffler. I am not to techy, so i go to mechanics. Right now we are trying to source a new oxygen sensor for the Duratec R500
