Rough idle at cold start
Hello
I wondering if its normal with rough idle at cold start ? is seems almost to missfire a little in the begining but allt the times its gone when its warm.
Is that normal or is it a problem i do have ?
The plugs are changed ?
Wire problem ? or only when the airpump work it makes the engine more rough ?

I is thinking to uppgrade the fuel rail and the injectors.
Asp pulley 180 mm
Evosport Shorty headers
82 mm Thottle body oe mercedes 550
Cooling upgrade eurocharged
Injectros eurocharged
Fuel rail
And maybe evosport wires if its solve my problem with the idle ?
Did you solve the problem ? or did its diseappear with the uppgrades ?

What was your car doing when you had problems. Mine has had some issues as well after larger injectors, EV 14 550cc's, you can see all my mods in the signature. Usually after a cold start with very light throttle it will start to buck, RPMs jump 200-500. Doesn't happen all the time, very spurratic. No codes. Just installed Zeitronix AFR and Dashdaq to see what is going on but it hasn't happened yet since I've installed. What exactly was happening with your? What did Jerry do to fix?
