hey guys..there is some problem in my G since past two three months..the car starts fine but after 5 mins or so...when im driving on lower rpms or 30-40 mph..its starts skipping and there are literally jerks which goes on for a min or less..it goes away if i increase the speed...when the engine is hot like after 10 mins of driving nothing wrong for the whole day...only happens on cold engine.

Took it to the dealer here but they can read my car's ECU as mine is US specs

Any suggestions?? I have a fujitha intake but don't exactly remember

 

Maybe?

Drivability issues as follows:
• Rough idle during the first minute of engine operation after cold engine start.
And/or
• Slight engine speed fluctuation during light throttle acceleration during the first ten minutes of driving after cold soak.

 

yeah it looks like the same as you wrote...so how to fix it??

 

I checked somewhere to reflash the ECU. not the dealer here cant read my G ECU ... so can i use Cobb or something like that to reflash it myself and can use it in the future for any error deletes??
