There are litearly hundreds of cel codes. Don't try to pinpoint which is which without getting the code pulled. Generally on the speed6, it'll be a gascap cel light, or a purge valve solenoid. Neither of these two are related to intakes.
You can get your cel read by either...
1) Finding a member with a CAN capable scanner and borrowing it.
2) Calling Autozones till you find one with a CAN capable scanner, and using it to pull the code.
3) Having a dealership pull the code (could result in a fee if its related to the intake).
4) Buying a CAN capable scanner.
Honestly, IMO, if you are planning on modding your car, you should have a full factory workshop manual, and the electronic equipment necessary to diagnose your car, PRIOR to modifying it. Modifying your vehicle gives YOU the responsibility of maintaining and diagnosing it.
