Rough idle...... again!

[shayne86]

Ok so playing with my obd2 scanner and cleared some o2 sensor codes while in the drive through coffee line. Car instantly developed a rough idle to the point i just turned it off while waiting. Limped home and can't seem to get rid of it.

I've pulled the MAF, and ran it, plugged it back in, cleared the relevant MAF code. I've currently got the battery disconnected to try and reset everything.

Starting to get on my nerves this car

Could I suggest it is something to do with your O2 sensors seeing it happened immediately you cleared the codes.

Regards PhilipA100% agree with you. Going to pull all the plugs, clean them (visible oil stain on passenger side one) and see what happens there before looking at replacing all 4.

Also for anyone who's interested i left the battery disconnected for a few hours and she runs like normal now. Go figure
