Code 11, 23

Post by rallyak »

Just recently I've been having problems with my wife's car. The car will die randomly even at highway speeds, it like someone turned off the key for a second. Code 11 has been there for years and I've cleared it many times but comes back in about a week. I figured it was a fantom code so I've done nothing with that. Code 23 I believe is new. It some times acts like it not getting spark but I wait for a few minutes and it will start just fine. I believe both sensors will act like this. Which one should I replace first?

It's your MAF sensor.

I had similar issues with mine back in the early 2000's. The car would randomly lose power. Sometimes I could keep it running, other times it would die completely. It finally left a code that confirmed my hunches it was the MAF sensor. Mind you I tracked this issue over a year.

Bad MAF confirmed,

It died this morning and wouldn't start back up this time. I unplugged the maf and started right up and I drove it home. It ran like crap and real rich, but made it home.
On my way to my dads to pick up my spare.

Good deal!

I wish I had the BBS as a resource back in the day when I had my issues. Now that I've had all my problems I just get to share them with others :)
