Did you replace the MAF with a new MAF (not a rebuild or used one) ? Or just clean it ?
Pretty sure it was new from Oreillys. I was thinking of going baack to get another just to be sure.Did you replace the MAF with a new MAF (not a rebuild or used one) ? Or just clean it ?
I appreciate any help, I got a guy with ECUs, and it id like to add it wasn’t bought with the issue. It pretty much started a day or so after it was received, as unfortunate as that is.Have you tried reading the ecu codes and see if it pulls a 55 code which means all clear or if it pulls other code they will be flashes. Lon flash is the first number quick flashes are ur 2nd number so if it blinks 2 long blinks and 3 short blink means the code is a 23. Then look up what the number is for the troublecode. Also you should check ur trans harness being an auto ur neutral safety switch could be faulty and not registering rpm and speed correctly. Which would cause limp mode at 2k to 4k rpm. Anther thing you could try is another ecu and see if the problem persists or goes away. Hope that helps you get started.
I’ll give it a look. But I will say it went on a 3hr trip there and back, no CEL thrown. Just cruised at lower speeds, stopped once because the temp went up slightly but when we stopped it shot back downSo sometimes when a Crank Position sensor starts to fail it will give issues only when the car is at operating Temps. Now if you are clearing codes and running the car it won't throw a code sending you into limp mode until the car gets to operating temps. I would try changing the CPS. Or Crank Angle Sensor. I can't remember what it's called on the S13
Yea that would be tough. Does it rev up normally in Neutral?I would post a video of it but I’m unsure on how to do that.
Nah, like I said, revs up when it first starts and sits for a min. After that, falls flat, needle bounces off around 3.5k and increases slightly and continues to bounce like a rev limiter. I’ll try and post it on YouTube to get a linkYea that would be tough. Does it rev up normally in Neutral?
I was taking a look at EGR , kind of confused on what that is. I heard it was bad, and I also failed to mention that the car has cut offf and stalled twice on that 3hr drive. But it’s made it home nonethelessYea that's not a bog that is definitely limp mode. Just need to Trace the cause of it. I would try a new CPS. Could also be a bad EGR if it isn't already deleted
I mean I figured it was new when I bought it, but I’d be willing to give another a shot.You have a bad maf my friend replace.the maf with a new one not a rebuilt or reused one. Car should not stay running if maf is unplugged should cut right off. Replace maf then come back and tell us if it has been resolved so we have definitive answer wether it worked or not
Replaced it with an older one , car ran for a good 30 mins just fine until it started hesitating at 5k rpm then slowly worsens to about 3k. Parked at gas station, wouldnt rev past 4k. Turned my car off and back on, revved it out fine. Was shifting kind of hard while driving, but then again it bogs in neutral also.You have a bad maf my friend replace.the maf with a new one not a rebuilt or reused one.
