Put a bottle of lucas fuel system cleaner in with 10 gallons of super gas. two minutes after the fill up my cel came on. took it to autozone and its throwing a p1128 code which i think is a mult lean bank 1...due to a failed maf sensor

any usual suspects? i want to avoid the stealership so any ideas are welcome, im a pretty good diyer so cleaning the maf, replacing sensors etc i can do just looking for some suggestions

 

what is "super gas"?

 

93 octane

 

3 days later CEL is out! i went on basic car forums which told me that sometimes the stuff needs to driven outta the car, i guess they were right. will have the codes erased tomorrow and keep you posted
