Been having problems with my IX since I wire tucked my injector harness. Triple checked everything and can't figure out what it is. Very eratic idle andwhen driving, I push the gas, and it lags then about two seconds later, jerks and pulls. I don't know what is going on. Here's two videos at idle. One was after the car was sitting and one was immedetly after my drive home from work.

Fixed the driving issue, had a loose O2 wire. But on cold starts, it still revs to 2500 rpms before settling down.

 

Anyone?

 

Are you flashed on tephra v7?

 

No, I don't believe so.

 

If you have just reset the computer it will start up like that and will settle down after a while. A few more hundred miles will should start up and idle normally.

 

Hundred miles?!? That's gonna happen everytime I take the battery out?

 

Yup

 

Mine goes to 2200 then settles down..

 

is there any plus's to unhooking the battery in these cars? Sounds like it resets the ECU for a relearn?

 

I did it today to install my mini battery and it doesn't seem to be as bad. I did notice that when I release my clutch the rpms drop by a hundred or so.

 

Yup. The computer is "relearning" your fuel trim.

 

So we got it semi figured out. Changed the values in the ISCV tables but my tach is still reading 200 rpms higher then Evo scan.

 

Also, my car ame with a crazy map on it and everytime we tried to load a stock map to it, it wouldn't start. Copied the immobilizer code and everything, and nothing. So today we noticed that Bit 3 was at 0, so we changed it in the stock map to 0 and it starts! So what's this mean?

 

Thank you for your invaluable and enlightening contribution.
