Hi


2007 X5 3.0 over 250K KM

Was having misfires on Cylinder 1 & 2 (Codes P0302, P0301) every other week; it was becoming worse and got a Reduced Power error so decided to change Spark Plugs and Coils.
Changed them (BOSH Coils, BOSCH Spark Plugs), old sparks where full black. No Oil in plugs.

Started the engine, no issues, idling fine, no smoke, all looked normal so I let it running for 10 min. Decided to take it for a spin around the block, but barely made it to the corner as soon as I rev it up past 3K rpm got a Engine Light and Engine Reduced Power message (+ AWD/ASC errors) - had to limp back home....


Read codes, cleared them, restarted the engine, idles just ok but got same error Reduced Power immediately (not even moved). Can't rev it up (of course)

Read the codes again and I'm getting these errors now:

-2CEC
-2CED
-2D09

These seem to point to Intake Manifold? Nothing was touched there......

No misfire errors.....but engine feels like IS misfiring....

Any leads/suggestions?
