My check engine light has randomly come on 3 times in the past 2 weeks both times within 2 hrs of me filling the tank, thought it was because the fuel cap wasn't shut all the way but after resetting my ecu, for the second time and it came back on i dunno wha it could be has this happened to anyone else or does anyone have a code reader so i could see what code im throwing, another possiblity is my 02 senors went bad for the reason i have no CATS but i'd think the CEL would come on within 20-30 seconds after resetting the ECU,

 

bad cat, bad O2 sensor blah blah blah, need to go gt et the diagnostic code fromt he dealer.

 

Just wondering where u filled up @? i put gas on base n it wasnt the right octane n it took out one of my coil packs, i replaced my o2 n nothing put gas in shell then it was giving me the #1 misfire n changed the coilpack and that was it. i knw the kalihi checkers and the salt checkers hav the reader, that wur i was gettin the readins @.

 

I've seen times where it takes several driving cycles before a service engine light comes on ( due to the ecm checking and reading bad sensor output ) this sometimes takes a while to occur as the car warms up, then gets to operating temp.

 

get on base 92 octane

 

i have an obd2 scanner if you wanna drop by aiea at night. im busy before work and finish at 930pm. tonight not good but maybe tomorrow night

 

pm me ur number my light is off for now but when it comes on ill it u up
