Pretty much stumped on this one. I'm thinking of trying another ECU.

Check out this vid of the misfire. http://imageshack.us/clip/my-videos/828/4ut.mp4/

I'm getting error codes 14 and 20. I've checked the Idle valve, replaced tps and o2 sensor. Also checked for vacum leaks and seems all good.

It doesn't start very well. Sounds like its going to stall but just about recovers to idle.

anyone got any idea's

 

so i've had another play around.

I maually grounded the iacv earth wire while the engine was running. The idle jumped up to 1500 rpm (still misfiring). I'm guessing the problems are seperate so for now i want to get all the error codes fixed.

Should the iacv be open (high idle) when the car is cold? I'm assuming the earth from the iacv is broken somewhere.

Would it work to wire the earth from the iacv to pin A9 on the ecu to test?

I'm just not sure when the iacv comes into play - most answers involve bringing the car up to temp but I would expect this to work when the car is cold???

 

found this info. interesting
