Evo 3 misfiring under load

[Gianni]

What fuel tank are u using. Probs no relation to ur problem but my engine cuts out when going round a right hand turn when tank is near empty coz I only have glxi tank which is single fuel pump. Doesn't have secondary so petrol goes to opposite side of tank when I get a sharp corner. Same happens if I plant my foot when low on fuel too

Alex it could be as simple as time for new plugs....so do that first. also check for good connection of the plug leads at both ends


if that doesn't help then try the following.

sticky or dirty injectors.
fuel filter blocked
damaged fuel lines when exhaust was installed???
fuel pump failing
fuel pressure regulator failed and returning all fuel
