So today I scanned my is 250 wondering what the problem was with it being sluggish and stalling in the Rpm and apparently the system is to rich. What can I do to fix this? Clean the maf sensor. anyone come across this problem?

I having the same problem with the same code on my is350. Hope someone can help

I think I fixed the problem, driving back home it felt usual as it was before the lights were off, unless my dad used the scanner to take it off. Need to ask him tomorrow but it went back to normal as of driving. I'll give some feedback tomorrow. Do you have an aftermarket intake?

- Faulty Mass Air Flow (MAF) sensor

yes i have an AEM intake so im almost sure that it has something to do with MAF sensor. But how can you fix this ? I dont want to get a new sensor and still have this problem

srt1

Get some sensor spray and clean (spray) that sensor. If that doesn't work you gotta find the problem. That's a cheap sensor, maf, compared to the o2sensors, which are far more expensive.

I had the same code and cleaned my MAF sensor and it cleared it up. I would try that first.

For most people they would take out the maf sensor and get the spray cleaning for the sensor at autozone and then clean it leave it to dry for about 20 mins and it should do the trick. If not I think it has to be another problem. I replaced my intake to stock and it did the trick. Going to clean and I'll keep you updated

Thanks for the help I'll try it out. Going to back my takeda back soon and see if it'll do the trick thanks again!

Will do thanks again!
