For the last few months now my vtr's had a really bad misfire, it doesnt matter what speed im going it chugs really bad and feels like its throwing the car forwards and its loosing power to the point where it sometimes cuts out. It doesnt like to idle when stationairy at somepoints either, it'l just rev itself and cut out but it goes through phases of playing up. Its been on a diagnostics test about 5 or 6 times and nothings been picked up.. ive changed the sparks, coil pack and crank sensor but ive still got it, anyone else had this problem or kno how to fix it?

I had the same problem a few month back, I just changed the spark plugs and worked fine after that.

as said check your spark plugs, give the car a good service.
See if it improves it

You changed the fuel filter? Clean the ICV, check MAP sensor

The car had a service when the sparks were done about 2 or 3 months ago but still no luck.. ive heard it could be the injectors or fuel pump.. more money :(

I only skim read it, as im meant to be "working"

I would agree with the fuel filter etc, are the plugs correctly gapped?
Run some engine cleaner through also

Fuel filter could be blocked up, happened to a mates a few weeks back. Very similar to whats happening with yours.

Guide above is to clean ICV :y:
