Can some of you guys have a look at Chunders Datascan log, I checked his ECU codes and it was showing code 34 when I cleared this it came straight back up as soon as the engine was started.

As you can see from his original post he has swapped quite a bit around but has had no joy:headvswal

34 is faulty det sensor or cabling (I think)

And I'm still sticking with my faulty coilpack theory ....

All the coilpacks were changed and we checked each connection with the origional coilpacks and sparkplug and all were giving of a good spark.

thanks bigsss, yeah i dont think the coilpacks are the problem, cheers though andyp.

 

Hey, thanks Berrica! very decent of you.

 

within about 2mins of pulling away from yours it started behaving very badly, totally missing all the fires, it got a bit better after 10 mins or so so i decided to continue home, but on the a89 or whatever to avoid a breakdown on the m8. By Edinburgh it seemed a lot better so caught the end of the m8 to join the bypass...oh dear, slowly got it up to seventy and then all hell broke loose. the rev guage started jolting wildly as did the car then it all went to poop and i ended up doing about 10mph down the hard sholder untill i got to hermiston gate and popped the hood. turns out the plug connectin the CAS was only just in, you may have knocked it loose when you were tightening the unit back up. Any way, to the point... it seems now to not be misfiring at all. Dont know if the knock sensor is still fooked(thus running on safety boost), but the major problem seemingly solved YAY! thankyou soooo much.

 

Would still appreciate feedback on the datascan that berrica very kindly did for me as it looks like alot of other things need tweeked.

 

thanks again, jamie.

Well sounds like you have some good news then. The Datascan images don't give a great deal away, being static etc., but nothing jumps out as being an obvious problem.

If that is the first time the CAS plug has been played with I would take it of and clean the connection!
