Check for codes and then get back to us. I'll bet the timing belt is off a tooth. I've SWORN to myself a million times it was on right, and messed with checking things for hours, before I re-re-re did the timing belt and it fixed it.

Sorry forgot to mention I already have and it only came up with low coolant level

I did have to solder the loom where the O2 sensor plug is because it had broken

I will take photos of the belt and post them up too

are your coilpack connections and injector connectors all tight? I used to have a problem where I could here them "click" on, but would still have to unplug and re plug them back in to get them to work.

Yep just checked every dam connection in the engine bay....
Do you know how I go about posting photos?
Has anyone had to solder a 02 sensor cable before I'm really wondering if this is the problem...
Cheers in advance....

I don't think your O2 sensor is causing this over-revving and/or back-fire you speak of. Pay close attention to your water temperature sensor. If it is truly revving too high or being difficult to start-up, then hunt in the area of the water temperature sensor or its connector. Also, ensure that all vacuum related hoses are connected.
