MAF sensor defect ?

[Rene S. Nielsen]

Hi Guys

Thanks for all your help so far. The Hummer have been sitting in my driveway for about 4 month, before the 1 (one) shop in Denmark was able to take it in (there are more shops, but not I would trust my car with)

After I changede the maf sensor --> nothing

Still giving maf sensor error and misfire on 2, 4, 6 and 8.

Changed the spark plug --> Nothing

Then suddenly the computer came on telling me no oil pressure. Checked oil, 1 cm above max ???? I have never put that much oil in it.

Well changed the oil on it, still no oil pressure.

This is what it looks like right now.

The shop tells me that the misfire was because of low oilpresure so the lifters (right word?) didn't open correctly.

Now they have to rebuilt the complete engine.

Any thoughts on what might have caused this, and please don't tell me I have been driving around with little or no oil
