I posted ther say about a misfire after changing everything. What everyone recommended I have and it is still missing it Is missin from exhaust before engine any chance it could be the cat?

nope wouldnt be the cat mate

Any ideas what it could be? Doing compression test tomorrow

start by eliminating each part in the ignition system one by one, also check the colour of your spark plugs ! also check the injectors, very difficult to give advice but pretty sure if you take it a local clued up mechanic he should be able to figure it out ! hope you get it sorted

I changed the plugs and the leads pulled then out one by one they wasn't sparking correctly change them all and the coil pack and rota arm and dizzy cap and it still doesn't work but my dads got one to look at it today so doing a compression test on it fingers crosse not serious thanks for the help

post back the compression figures

bad spark in the ignition system could also indicate bad earth point somewhere !

easy way to eliminate this is to use a spare jump lead and earth the engine and a good point on the chassis, its very well known for the coilpack to rot aswell which can cause this

Sorry for late reply my car is all fixed now I had a bit of water in the first cylinder whole and the Rita arm was cracked ok good note it's all working & the compression test was 153 on every cylinder

good job, commonly happens when people wash the engine bay but usually the rota arm and dizzy cap hardly been change in its life so its a must (to change it) if of owning a gt/glanza
