Hi, I am new to forums and have been researching about a problem with my Ford S-Max (2008) 1.8TDCI which kangaroos and looses power at around 2,500 revs. The engine revs fine when in neutral. The engine management light is not illuminted and I dont get any errors/warnings/lights on the dash at all. I've noticed a strong acrid smell after driving. After reading up I have tried a few things but without success-
- I have disconnected the battery for 30 mins and reconnected. This gave no improvement.
- I have disconnected the wire to the Mass Airflow Sensor to see if the drive improves. The engine seem to rev a little higher before kangarooing. The MIL illuminates when disconnected and goes out again after a short while when I reconnect.
- I have replaced the Mass Airflow Sensor with a new one from an eBay seller who appear to be have a thorough ebay history. It was advertised as genuine Ford part. This gave no improvement.
I have read that the acrid smell could be due to fuel starvation and a possible cause could be a faulty advance solenoid. On turning the ignition on, I do not hear any clicks at all from under the bonnet. Is this normal? Should I be hearing clicking from the advance solenoid and/or from relays in, or around, the fuse box?
Any advice is much appreciated as I can't afford to get a Ford dealership to diagnose my problem.
