Got a problem with a 20XE
The engine turns over and will run but it will not run on all cylinders, also backfires.
I have replaced the dizzy cap and rotor checked/cleaned the plugs (showed signs of over fuelling so I replaced the temp sensor) and it gives a spark but maybe not as strong as I would like but more than enough to fire.
Also checked timing belt
Fuel pump is run when its should do
The ECU is not recording any fault codes so I’m guessing that all the other sensors r fine
