Re: problems with cylinder firing order.

well the coil pack should have the cilynder order on it ( 1,2,3,4 )

i can't remember where cylinder1 is .. could be the closest one to the coil pack or the one at the other end.
try both!
after you find cylinder 1 the rest are easy 2,3,4.

Re: problems with cylinder firing order.

The coild pack has the cylinder numbers printed on, so does the cylinder head but they are harder to see. Anyway...

Engine order is;
Cambelt | 1 | 2 | 3 | 4 | gearbox

Coil pack order is;

Re: problems with cylinder firing order.

Could also be:
-the stepper motor, wich controls the idle;
-dirty butterfly case;
-broken throttle position sensor (also on the butterfly case);
-broken TDC sensor (rpm)
-broken camshaft sensor.

Pick one and test it. Or test all.

-stepper motor: easy test - take it out leave it connected, and put someone to fire up de car, if the pin moves, that means that the motor is trying to adjust the air bypass => it works.
-dirty butterfly case: clean it.
-broken throttle position sensor: you could check it with a multimeter (don't remember what ressistance should have), but you could also change it cause is pretty cheap.
-broken TDC sensor: check it with a multimeter, should have somewhere between 750 ohm - 900 ohm, at 23 degrees Celsius.
-broken camshaft sensor: check it with a multimeter (don't remember what ressistance).

You could also try to take it to a tester, to see if it gives up anything.
Good luck.
