    hey guys ive just chaned the spark plugs and leads car starts fine but when i rev it back fires from the throttles i did put 40 litres of e85 petrol on a empty tank

    could this be the leads being mixed around in a different firing order i think i done it rite though or could it be the fuel leaning it out

    I'd check the leads - backfire thru the throttle body is typical mixed up plug lead symptom.
