I took my Saxo VTS to a garage to have the fault codes read out as my car had been stalling/not starting and running rough intermitantly. The computer gave two faults they were roughly as follows.
Intermittant Mixture adjustment high limit Intermittant Mixture Fault......
The bloke at the garage said it probably down to a fuel pump/filter fault or water in the fuel which is fair enough and im gonna check this. I asked if the lambda sensor could be the cause as its meant to measure the oxygen content in the exhaust fumes and alter the fuel/air ratio to maintain a certain oxygen content. My thinking is if the sensor is giving a wrong reading then the fuel/air ratio if changed to sompensate could cause problems like im seeing.
The reason i question this is because the Lambda sensors are known for causing similar faults on saxos.
