car- 06 evo ix
mods- AMS TBE, tune, open filter, mbc.
The cars had all these mods for atleast 5-8K miles with 0 problems. The only thing that has changed recently was that the dealer changed the 3-5 synchros probably less than 50 miles ago.

Any ideas?? The car runs great and pulls as hard as it ever has.

Thanks for the help.

 

any ideas?? I've reset the light and it hasnt came back in the 30+ miles of driving....

 

Could've been a dirty filter/dirty maf sensor. Is your air filter oiled?

 

don't think so, probably due for a cleaning though. It's whichever one ams sells, there cone filter.
