2005 RX8 A/T 70K miles, recalled engine at 2011, 4k miles on new engine

Well I just got the oil changed today(first time after I have my '8), switched from 5w 20 to 5w 30. after that I noticed:

When I switch the key at ACC position and don't start the car yet, if I keep this status longer than 1min(usually when I am setting the GPS or changing disc), the CEL will flash few time(3 perhaps), then stopped, then I start the car and the light turns off.

for the first time I didn't pay any attention to it. but found this happened now and then, when at ACC and before starting the car.

Anyone has an idea?


thanks in advance!

 

BTW, I cleaned the MAF days ago, so that might be the problem?

I did clean MAF couple times before, tho- found no similar problem

 

I don't believe that's an issue? I think that is standard/typical. If you were seeing it while driving, it would be a misfire, but there is no misfires with the car off.

I can tell you, changing the oil, and/or changing weights, will not affect the CEL by themselves. If there is a connection to the oil change, then something else happened. Something like overfilling the oil and it got on the MAF or something got disconnected, etc...

 

i did the same thing on mine, went away after a while. never knew what it was
