Occasionally I get a rough start and I assume it's from the XEDE because the car always cranked fine without it. The last time the car had a rough idle on start I let it idle rough and seconds later it started acting normal. I usually just cut off the ignition and try again.

Well today the car started normally but when I got into boost I noticed it being rough and lacking power and then I noticed the constant CEL, had it scanned and it came up P0102(Mass air flow sensor circuit low input). I pulled over, shut off the car, sat for a few seconds, cranked it (waiting for the fuel pump) and it ran fine. I was thinking that maybe the XEDE did something that the ECU didn't like.

Should I just reset the ECU and see if the CEL returns before I decide I need to replace something?

Car is stock except for up-pipe, TBE, and XEDE with stage one map.

edit:
Just went out because I was gonna clear the CEL but first I was gonna drive it so I cranked it up and the CEL was gone. Drove it a bit and it seemed good. The MAF has never been cleaned or removed and the car has 26k miles on it, does the MAF have a scheduled service time?

 

are you running an oiled filter? if so the MAF could need to be cleaned. even if not, it could need to be cleaned.

search on here or nasioc for the cleaning procedures so you make sure you don't damage it.

 

My filter is an OEM filter with just over 5000 miles on it. Either way I'm gonna check for the cleaning procedures in case the CEL comes back.

 

I've had that code thrown once. Was very very late at night and my car was parked outside of a friends. Started the car and it idled a little rough for a split second and seemed to be idling a little higher than normal. Instantly threw that code. I reset the ecu and it's never happened again. I talked to Shiv and he said it was probably just a random code and not to worrying about it since it isn't recurring

 

Yeah that's what it seems like. I've driven at least 300 miles since then and it's been just fine.

 

hmmm just got another CEL for this same code. Car was sitting at work then when i started it to leave the CEL instantly came on and the car idled at 2k (cold start idle is usually around 1700 and 950 once fully warm)

Does anyone who is familiar with this CEL know if it puts the car in a limp mode. It's strange because on the way home i noticed my idle considerably better while in stop and go traffic. Usually when i clutch in it will stumble down then come back up (MAF is really close to the turbo) Now the idle is great and doesnt stumble that much. But whats strange is the car doesnt seem to pull as hard and i'm not getting any pops from the exhaust like i usually do when i tap the gas
