1. Does this engine have an IAC valve, if so where is it located.

2. On the upper left side of the airbox, near the dipstick, there is a tube with vacuum present that plugs into the airbox.

   What Is this for?

Still struggling with this low power problem

1. Coilpacks ok

2. Plugs ok

3. MAP sensor new ok

4. Coolant sensor new ok

5. TPS smooth action to 100% on scanner graphic and percentage

6. Throttle body bench tested ok

7. No vacuum leaks

8. Fuelsys1 OL cold then CL hot then OL-Drive when foot down

9. New airfilter

10. Fuel pressure at Schrader fine (not measured, but it blasts out hard when valve pressed

11. Scanner says EVAP working ok

12. Even changed out the autobox ATF.

Still the car runs VERY slowly when hot, like 10-15mph max and about 30mph when cold. Foot flat to the floor even in low gears.

This fault happened at about 65 on a dual carriageway, power was just suddenly lost after running normally.

90k miles and serviced every 5k.

If anyone has any other suggestions, they'd be very welcome. 🤔
