Hey all,
Since i had the exhaust done it seems my car is backfiring out of the exhaust (not cool as it's got brand new cats haha!)
I've changed the plugs with new ngk platinums and changed the leads as well with top gun 8mm....
Only thing i can think of is O2 Sensors are bad or need to be cleaned?
I have disconnected the battery whilst doing the plugs so the computer would have had to re-learn what it can..
How hard is it to change O2 Sensors?
When i did the plugs i cleaned the MAF screen as well (had a bee or two in it ) and put a new air filter in.
Eventually it's gonna get a mafless tune and otrcai but that won't be for a month or so as i need to save some cash.
Also to add, It seems it only backfires sometimes, normally when the car has been driven for a while (30mins +) and is most noticable as a jerk in power in 4th gear climbing a slight incline ie: freeway.
Another thing i should add is the check powertrain light has illuminated for a short period before but never whilst backfiring and has always gone after a restart.
Car is still running fine otherwise.
Cheers,
