Yes I did read multiple threads on this issue... I just installed my intakes and I have a G25 VQ25HR. Now before anyone says anything I made sure 100% that those intakes will fit my car. It fit perfect no problems. I have a rough idle, its shifts weird and the motor sounds like its choking. I reset the ECU, nothing. I cleaned my MAF and throttle body and after that it got a little better. Also I double checked connections for leaks and everything is fitted perfect no leaks. On my obd however, at first, I read 16 codes. I didn't do anything, I checked again the next day I read 4 codes. Yes very weird. All those codes are about my MAF. So should I change my MAF sensor? If so, should I stick with OEM sensor or does anyone recommend something else? And if not, How do I fix this problem?

 

you were sure the plugs on the maf sensors are seated well? none of the wires leading up to the maf are frayed or damaged? if you delete the codes does it come right back?

 

The sensor is seated perfect and the wires are not damaged. As for the codes i cant delete those 4 for some reason it says its my MAF sensor so idk.

 

Have you tried resetting the ECU, neg battery term off over night? You did drop either of the MAF's correct? have you check the TB connectors, I know they don't come off for the install but may you knocked it off or lose?

 

I reset the ecu and its still was the same. None of the MAF's were dropped and the connectors are fine and it they werent i shouldve had a code for that but my codes only ready MAF stuff

 

What are the codes? If you have a leak AFTER the Maf it could be causing problems. It's also possible you damaged one or both of the maf sensors... they are kind of fragile.

 

p0113,p010c, p010b, p0101 there is no leak i checked it there is no leak at all. Also i checked those codes on google and they have to do with MAF. do i have to replace them cause my MAFs are the factory ones

 

Did you plug in your intake air temp sensor?

 

Just curious if the OEM intake runners on your G25 are different in volume vs. the intakes in the G37. I'm not familiar w/ the G25 V-6 hence the question.

 

the only thing that got disconnected was MAF. can you show me a picture or tell me where the temp sensor is?

 

The temp sensor is integrated in the MAF unit on the G37.

Having all those codes at once...Sounds like MAF is damaged or the wiring to the MAF unit. Double check all connectors and wiring bundle for issues.

 

Would you recommend me getting new MAFs? If so, which one do u recommend. A couple people told me to get performance ones.

 

One guy tried putting R2C intake for G37s in his g25 and had the same issue and he stated that he had to go back to stop because something was different I think in air flow

 

Ya but i think i can be able to run it with a high flow MAF. Cause either way the stillen gen 3 fit perfect but im guessing my MAF cant handle that much airflow but im still not sure

 

That was his problem not the fitment but good luck
