I just got it back from the shop yesterday for having valve cover/gaskets/spark plugs an tubes replaced and I start it up and start driving today and service engine soon comes back on. I look in the mirror and I see smoke coming from the exhaust and start tripping. Went back home and plug it into the code reader and code P2189 comes up. Along with all cylinders miss-friring. What code be the reason and possible solution to fix this?

Any help would be greatly appreciated

 

On top of each valve cover is a round crank case valve. Check to see if they were replaced and or installed correctly. Its a very simple device with a cover, diaphragm, and spring. To remove the cover use a small screwdriver and gently lift each tab up. If they are old, replace them anyway.

If that doesn't work you may have a good vacuum leak.

 

You see smoke and thats not good. You could have carbon build-up in the heads. Sounds improbable for a high tech car like this, however if you do your research you will see its fairly common in the 545 and 745. Even after replacing the secondary air system and valves at the rear of the block, you may still get the same codes. The smoke is a sign of something bigger going on... its approx $3-5k to have the heads rebuilt... good luck and I hope this isnt your issue!

 

Thanks for the info guys! Took it back to the indy shop this morning and found out that they installed an updated Valve Cover model and not the one that was originally with the car. It didnt have the CCV on it and a hose wasn't plugged back in! So I was pissed because the mechanic knew it wasn't right but just proceed to go with it anyways. Should have it back tomorrow or Wednesday
