My guess is that if substantial damage was done you wouldn't have a problem with it running rough... it wouldn't run at all! Don't use it until you've done the timing properly using a kit. Buying (£65???) is a bit steep for something you're not going to use so much; agreed. Find Autovaux online and hire from them.

Right, I got home tonight and did the pedal trick (thanks to all for the helpful threads and advice). It was showing code 0100. I proceeded to strip down to the cambelt again and discovered that once I had put the crank lock on, three and four bank were spot on and two was out maybe 1 tooth and number one was out a tooth and a half. I reset and fitted correct locks this time!!!

Haven't finished putting it back together yet because I lost light, but I hope I have been lucky and have learnt my lesson.

Would the code in your opinion point to the timing being out?

Yup, thats a code for the MAF.

what we dont know, is if it was there before, or whether youve accidently missed the connection, or its not made properly, so double check that 1st.

the 2.6 and 3.2 MAF's are the least reliable of the bunch, so maybe time for a new one.

Personally I would buy a Bosch, from ebay ,or vauxhall parts world, wherever has a good price at the time.
My advice would also be to avoid the cheap chinese copies, often just a resistor to fool the ecu.

Well done on sorting the timing, doesnt sound enough to cause a mechanical problem, but sure as hell wouldnt run well / economically / powerfully, you will prob get the cost back on that kit in saved fuel Thumbs Up!

No there not, a resistor would do nowt and the ECU would spot it straight away. Thumbs Up!

Agreed, the valve timing will be out such that the airflow will be affected (and hence the measured airflow will be less than expected by the ECU given the throttle position and revs)

Sorry for the late update guys - I was away for the weekend. Well I ran the car up and phew it was fine! Apart from now i can't get rid of the spanner light on the dash!

If anyone reading this is even considering doing the timing belt without the correct locking kit - seriously don't!!! I was lucky this time.
Locate the kit by whatever means and follow the DVD and you can't go wrong.

Thanks to all who contributed for the kind advice.

Reply #58 - 16. May 2011 at 08:23 Glad your finally sorted and the car is fine(ish) Whats the fault code? Still the MAF one? How many miles / starts have you had since sorting the belt?
