    I got a 05 Chevy n i was wondering if yall could answer my question,When my truck is idling for 5-10 minutes it will start smoking out of the tail pipe n vibrating the hole truck,My Service engine light stays on all the time but when it start smoking the light starts blinking and u can puch the gas peddle all the ways to the floor n it will stall out but i can kill it n turn it right back on n it will b fine,A couple weeks ago i was hauling some stuff off for a guy n i was loading it up on a trailor,It started smoking so i went n killed it after i got done loading that stuff up i went 2 start it n it wouldn't do nothing not even try 2 crank over,Lights n everthing was on but wouldn't do nothing else,i had a guy look at it he hooked it up 2 a machine n it said The Bank 2 Sensor 1 was stuck on Rich,and Bank 1 Sensor 2 was stuck on Lean,I ordered a Sensor 2day,Do yall think the sensor being bad would make the starter not turn over or is the starter jus goin out

    In the future when the service engine light is blinking it needs to be taken care of asap. When the light stays on its usually emission and it should be fixed but it can wait.

    IM not sure that the starter is going out.
    As to the lean sensors i would for sure get them changed ASAP so you dont damage your engine. Also when was the last time that you did a tune up? That will help keep everything happy as well.

    I would at the min scan for codes when it comes on.. and when it is blinking it means that you have a severe problem that needs to be dealt with.
