ECU problem
hey guys, I'm new here, and I have some questions regarding to my Celica. Couple months ago I was driving in the rain, and I have the Injen Cold Air Intake (the one that is next to the wheel) and I drove over a puddle of water frown yeah, and it messed up my engine or somewhere, I'm not sure. Couple weeks later, I decided to take off the filter and clean it. But now, my car seem to have trouble accelerating. It seems like the car is lagging when I'm trying to accelerate. Whenever I try to floor it, and when it reach 3000RPM, it kind of paused a little bit, and then slowly increase the RPM... Then lately the check engine light came on, I took it to the shop and they told me that my car is running too lean.. I have no idea what he meant by that. I tried to reset my ECU (maybe that was a no no) and now I don't know what else I can do. The check engine light came back again, and I still have the trouble of accelerating. If anyone have any idea, please let me know.. thanks

If it was enough water, it might have damaged the MAFS. The MAFS uses heated elements to detect airflow and temp, so the cold water could've messed it up. If the MAFS is just dirty, it would've created some bogging at low RPMs, not midrange.

I sucked up a puddle and almost locked my engine. I don't know what the exact diagnois was, but the dealership only charged me 80 bucks for the diagnostic check. I could rev over 3 grand either.

My advice is take to them and get it looked at. What filter were you using? I have a K&N now and it seems to be ok. I had a Ractive filter when it was pouring outside. Bad idea.


Those who knew me, knew me well.
For those who don't, can go to hell.
