well the CEL flashed once a few months ago when i was the highway on ramp trying to merge with traffic, i had to get it up to 80 to get past this damn car that wouldnt move over for me.. once i hit 80 BOOM, the CEL flashed like 5 times.. hasnt done it since.. and its been a few months now.. would the computer still store that incident to where i could read it... and i personally dont have HPT, but my friend does, so i could go to his house if needed be...
