please help....
« on: 09 April 2010, 16:10 »
got a bad misfire this morning.... checked plugs and they werent too good (over the 0.8mm recommendation) so new ones going in tomorrow....but i also did a scan on vagcom and it brought up the lambda sensor malfunction...

would a bad misfire from the spark plugs cause the lambda fault to show on vagcom or has this maybe gone faulty too...?

another question is when cleaning the MAF is it ok to just squirt the electrical contact cleaner through the plastic mesh on the MAF......?

thanks ......

Adrian

before you put your new plugs in pal erase the code  put the new plugs in then  re scan after a few days
 not too sure about the maff sensor tho pal
