[Nixk]

hey, my name is Nick, i have a 01 echo(platz)turbo(since this morning),,, im new on this forum. i have a little problem with my car. i started tha car this afternoon for the first time and it is rough idling and when i press the gaz its like nothing happening but sudently it goes....... then nothing.... then go etc...my MAF it next the TB then BOV to IC to turbo. my wideband indicate about 17 afr at idle witch i dont think is normal with my 1zz injectors, anybody had this problem??
btw i have a FIC not plugged yet, i dont think its supossed to run like this even without the fic cuz as a read in the others threads the engine should run normaly but a little lean.
hope you understand what i mean
