hard to diagnose without seeing, but check your air filter make sure it is clean. probably not the issue but possible coilpacks.

Was it on the same take of gas?

Is it an automatic? If so maybe need tranny oil and filter changed.

If it is not throwing a code it is one of two things. the problem if mechanical. or it is happening with such irregularity that the computer is not storing the code long enough to trigger light. normally if occurs once the code will store for short period without engine light. if occurs again or multiple times while code stored then light will trigger.
