Engine ideling ruff

[AirStrike]

Hey all just a quick question on what people can think of to help with the ideling of my car, seems to very ruff. Also loves the fuel, lately only seem to be getting around 400-450kms from a tank!
I have replaced the spark plugs, new leads go in today, exhaust is stuffed so is gettting fixed (might effect back pressure).
I havent done a fault code test yet, will get to it one day.
So anyone have some thoughts on how to fix it............

make sure your get the correct spark plug gap, should state in your owner's manual.

have you tried cleaning your throttle body

 

[AirStrike]

Spark plug gap is correct (1.5mm). Throttle body im gonna do sometime next week.
Keep the ideas coming.

Could be valves starting to crap themselves..increased fuel usage, rough idle..just possible

could be you o2 sensor is stuffed and you car is operating in an open loop causing you to use more petrol.
Maybe.

fuel filter? fuel injectors? mines got a rough idle and it stalls changning gears (R to D) etc, its caused by a leaky injector aparently

I have a fuel filter here to go in, got new leads today, injectors I am organizing......... for the sake of $100 I might replace the O2 sensor.

just a query, most mechanics these days have a computer scanner thing, why dont you get them to check it out, coz they read volts to sensors, how well the oxy sensor is running, temperatures etc, check for errors codes to. well worth 20 odd bux if you can find a mechanic to dso it

I will be going to see the boys at Blue Chip Tuning shortly so they can have a look for me.
