we need a bit more information.

are you talking during cranking after the car has been sitting overnight OR after you driven the car, stopped, and attempt to restart again?
Does the cold crank hesitation happen at all tempratures or just when it gets below a certain temprature?

What mods do you have?

Thank you figgie for taking time to answer. The hesitation happens when the temp is bellow 20 and just after cranking when the engine tries to maintane cold rpm.

Are you having any codes at all?

the most likely issue might be the cold start injector. If it has never been removed, it is going to be covered in oil and black stuff!


test the cold start switch

MK3 TSRM On-Line


You will want to calibrate the TPS per the TSRM
