Quick tip for all you 1.9 mjet guys
Was told at the weekend while cleaning out the egr valve on my friends astra ( same engine as my GT) that while cleaning the egr valve, its a good idea to give the MAP (boost) sensor a cleaning aswell
Its an easy job as the sensor is located just a bit further up from the egr valve on the inlet manifold.
After doing my friends, I had a quick look at my sensor, but wasnt expecting it to be to bad as my car runs well. i took it out and the sensor itself was completely covered in a very thick layer of coke!
after picking at the coke and soaking it in carb cleaner for quite some time, i got the sensor completely clear. BE CAREFUL NOT TO DAMAGE THE SMALL SENSOR ROD IN THE MIDDLE.
The car now runs alot better, it has cut out a lot of the lag lower down in the rev range, and it seems to boost alot better now!
