I think my injectors are gone. If the car is on gas it runs fine, but whenever its on petrol now, it wont idle, it will not rev properly. Like its missing real bad. So ive ruled out plugs/leads/dizzy as like i said it runs fine on gas.

I suppose it could be the maf aswell? Maybe fuel pump? I dont think its the maf as I have disconnected it before when everything was working fine and the car didnt act like this.

How can I test the injectors?

how long before now did u use the petrol?

The petrol gets used everytime the car does as the car needs to be started and warmed up on petrol.
