The check engine lighthas come on and the LED in the engine compartment flashes 8 times. I don't have the fault codes but while at MB for parts I asked one of the techs and they told me that 8 flashes means the altitude compensating capsule is inop or that it could be triggered by lean mixture. I recently replaced the fuel accumulator because of hard starts and the injectors because they were the original ones. The car has only 57,000 miles on it but I realize that time is an enemy as well. I replace the alt compensating capsule (located behind the battery) with one from the wrecking yard . i was told that this particular part rarely fails. The light is still coming on . Perhaps the exteme heat here in Phoenix AZ plays a factor? Any help would be appreciated.

The EHA valve was also replaced due to the fact that it was leaking fuel; this was replaced at the same time as the fuel accum was replaced. I had this done at a shop here in Scottsdale and they told me that the mixture was okay but that i was on borrowed time with the injectors. It was after this maintenance that the "check engine" light came on. I went ahead and changed the injectors myself.
