Engine Runs Weird, Still Error Code 21

[Alecci]

I previously had a thread here about getting the car started... Well, the car is now started. The problem was discovered to be the CAS, that probably took a bit of beating during the crash some 15 months ago. The CAS has, of course, been replaced by a brand new one. Car still don't run as it should though.

Idle is very bad, ranging from about 500 to 3500 RPM, when hitting the lower revs it sometimes dies altogether. At lower revs it misfires a lot and and sends loads of flames through the exhaust. At higher revs it runs much better, almost like normal. All of this applies to idle.

Fuel pressure is rather conservatively adjusted at about 2.5 bar and injector lag times are almost what should be (lag times are 1.04 ms and should be 1.1 ms).

We've been able to found out the following:

1: We still get error code 21 (primary ignition signal).

2: One of the camshafts are about 1-2 mm off since the workshop replaced the oil seal down by the crankshaft.

3: Ignition angle has been set at either 16 degees before TDC or 27 degrees before TDC.

We've not yet had time to properly adjust the ignition angle, which I think should be set to 20 degrees before TDC?

The front end of the engine is being taken apart as we speak to fix another oil leakage, and the camshafts will be properly adjusted this time.

So, could the faulty camshaft position or the faulty ignition angle, or a combination thereof, be causing the symptoms we've been experiencing? Could they even be causing the error code 21?

The car is due for mapping on Tuesday 24 June, and that's the last available appointment before the middle of August. Missing this date would mean no car season for me, so time is of the essence. Any help would be very appreciated.

have you tried replacing the ignitor module to clear code 21?
