If you have read my last couple of posts you will know Im having bother with my cosworth.

I have ruled out the TPs switch after much fannying on today, map sensor looks brand new too. It sounds as if timing is all to shit when it starts. Its still flooding up but will run for a few seconds if you hold about half throttle, it will rev then drop off rev then drop off a few times over before it cuts out. Then it wont start again for a few minutes and does the same when it does.

Timing looks like its out around 2 teeth out on exhaust cam pulley. Its got Kent pulleys on so Im only going from someone elses paint markings. No proper markings on the pulley.

Anyone experienced this before or able to give me a suggestion to try?
Please please please, Im sick to the back teeth of this. I just wanna drive her!

Thanks in advance and thanks to all those who have helped and suggested things so far.
