I got the new stock exhaust on now and it is extremely quiet which is good but it still is not running right. it is kind of surging as it is idling. im thinking maybe my injectors could be blocked. Is there any other suggestions? Its kind of driving me insane :S
Thanks guys

so is it the car not running right, or just a funny idle?

What have you done so far to diagnose the problem? If a sensor has s**t itself, EEC may be aware of it and a diag readout could reveal a lot!

are you saying you put the stock exhaust back on? did you have a sports exhuast before? maybe your cat converters rooted?

f**k, in that case the fuel system is probably f**k. the oil might have damaged the pump impella or collected at the bottom, mixed with debris in the bottom and gone to the filter.
the spark plugs are probably discusting, oxy sensor could be well and truely covered too.

You might want to replace the fuel filter then. It is located under the car near the rear passenger side. I would say it is most likely blocked with crap that was picked up when the oil was accidentally put in. Injectors should be fine I would think due to the filter doing it's work.
Not hard to replace...just got to remember to release the pressure in the fuel line. phong =P~

just jumped under and seen that there is 2 fuel filters and they have both been replaced. it was a long time ago so im guessing i just forgot about doing it... so maybe oxy sensor? does anyone know where i can go and have the computer checked for fault codes and approx how much it will cost? cheers
