I have an LL Bean H6 2003, and after its warmed up( about 5 to 7 minutes) it idles at about 350 to 400 in drive position and about the same in park. I think this is too low

Just wondering if this is normal. What does your car idle at ?

much appreciated

There won't necessarily be any codes. Sometimes a mechanical issue can occur and the computer doesn't see it as a problem.

You may also want to check the performance of the TPS. If it is sending improper data to the ECM, just off of where it should be in relation to the actual throttle position, it would idle low.

Yes, you can switch. Perform a proper engine flush prior to switching to remove carbon deposits left behind by the conventional oil and the synthetic will perform as though the engine had it all along. Less friction on the internal components which adds to less wear, lower engine loads and better fuel mileage. The synthetic oils adheres to the surfaces better and don't have the breakdown rate of conventional oils. They also withstand high temperatures better.
