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
E85 on stock fuel system = fail you need some serious upgrades to run that shit
I tune the oldschool way fear on the passengers face and knuckle colour cant go wrong
tabbacco is still my favorite vegetable
ive already got the upgrades just hasnt been dynoed yet going in soon
also gonna change the o2 sensor
what kind of upgrades do you have?
1995 Manual HSV Clubsport
Wade Cam :: 9.2:1 CR :: Pacemaker headers :: Twin 2.5" Exhaust :: VT Brakes
1991 Supercharged VN Berlina
9 PSI SC14 Intercooled :: Genie headers :: Twin cats :: HM Twin 2.25 exhaust :: 3.45:1 LSD
high flow injectors 38lb high flow fuel intank fuel pump 044 with malpassi fuel reg
I'd check the leads - backfire thru the throttle body is typical mixed up plug lead symptom.
*** i knew ive done something wrong il get my bro to check it out his electrician
