Hi, guy:

Need to see is this normal, this is what I did:
1. Jack up the car;
2. Idle in 800-900
3. Gear in natural

A. Spin the front ( Left or Right ) tire, won't affect the RPM.

B. But spin the rear ( Left or Right ) tire, as long as the tire still spinning, the RPM will raise up to 1200RPM.

Is this normal?

Interesting, just curious what possessed you to do this? I have no clue and do not plan on trying this in 20°F weather.

Not surprising. The car probably things you are starting to roll and kicks it into a high idle to make clutch engagement a bit easier.

As mentioned to you in your other thread, there is a rolling idle speed and it is greater than the stationary idle speed.

Thank you for your feed back.

Send the car to dealer for over a week. All the reading from the Lotus Techcenter is A OK. So not sure what's wrong.

Simply just ran out of resource, that's why try to ask for help.....

Tried:
1. Put back the 260ECU
2. Put back the stock Airbox
3. Delete the catch can
4. Put back all stock vacuum line
5. Replaced MAF multi times
6. Replaced Pre Cat O2 sensor
7. Put back stock intercooler
8. Compared paddle sensors data vs other known good Exige
9. Checked spark plugs
10. Switched off accusump

Only thing did not change back is the 550 injectors & the 2.9 pulley.

Anything that you can think of, please?
