Re: no code ?
update
do have a code 45, o2 sensor not long ago and I would think lite would stay on if o2 was bad? next is evaporative canister, the small line to the tbi is cracked at tbi could this be it? took line off no diff. in the engine sound at idle. Do the canisters go bad? how do you check and where would I find one. Thank all Mike |

Re: no code ?
I get the 45 code every once and awhile, if I get on the throttle to hard.
