itscoo2pyopants (not sure about that handle!!) thanks for the help. I have replace the coil packs if I still have problems I might hit you up for the diagnostic help.

This is what I did today on the X5;
-Cleaned the MAF sensor with MAF cleaner.

-Replaced all the little vacuum hoses I could find. Some look pretty bad. Remind me to not do that again. Found a 8mm vacuum plug under the intake manifold cracked and poorly fitting. Replace that plug.

-Checked the fuel pressure. Followed the procedures in my Bentley service manual. Had zero pressure when I connected the gauge. The book said I should have 50 psi+/- 3 psi engine not running residual pressure. With the fuel pump jumped and engine not running I should have 50 psi, that was correct. With engine running I should have 36-47 psi that was good. Once engine turned off the psi slowly, slowly creeps down. I suspect the pressure regulator is bad.

Ill order a new fuel filter and pressure regulator.
Ill keep you posted on how things go.
