Hello!
When starting the engine runs irregular/rough at about 500 rpm, then after 10 seconds the engine revs up to about 1500 rpm, the rough idling disappears but the engine warning light goes on. Also, the engine runs a bit jerky until the accelarator is pressed hard, when engine is warmed up the problem seems to be less. Before the problem the car had a leak headgasket wich has been replaced, before replacement the engine ran fine. after the replacement the problem occurred and also the A/c stopped working as well as a bruning airbag light.
Does anybody know what it can be?

if the CEL is on then get it scaned... it could help much.

are you sure the timing belt is installed correctly i.e. the marks on the cam & crank pullies are correctly alighned?

are the spark pluig wires in a good condition and installed properly?

is the MAP sensor's vacuum line properly installed?

is their any other vacuum line lose or disconnected?

I let the dealer read the computer, it says map error 33, he also connected a vacuum line, will now have to wait till after the vacation.
