MAP sensor. Its ontop of the engine towards the back. Unplug it and see if it runs better without it. I had this problem with my 1.8. Used a MAP from my 1.4 and it fixed it!

Did it suddenly go like this? I had a similar issue on a 1.4 a while back where the coil pack failed, but it spiked the ECU, and even after the ECU being 'fixed' it still was never right and I ended up selling it on.
You could also check the earth points incase they're dirty/broken, gearbox earth and ECU earth at least.
yeah was running fine and just went like this think ecu is gone on it as checked everything includeing earth wires no need to find same ecu as mine but no luck yet
yeah just went like this think is ecu causeing probs need to try get one been looking 3 week or so now but no luck
