Problems with sensors and NX MAF KIT I just got a NX MAF kit installed on a 02 Trans Am, used it once, and the car came back with a check engine light, got it checked, and its the front 02 sensors, and the Mass Airflow sensor, got the errors cleared, but how can i fix this so it wont happen again. Dont want to delete the sensors with ls1 edit, trying to find a fix. thanks

Wait you sprayed it once and all of a sudden you got these error codes? What were the actual error codes? I wouldnt think you could or if you could that it would be a great idea to delete your front o2 sensors? Am I wrong on this ?

Dont know exactly but ill write them down next time, found out the car was running lean so i changed the fuel filter, and i checked the bottle pressure and everything, and the sensor came on again, not sure but i think it might be a electrical problem, is anybody else running a msd window switch with this setup. thanks guys on the info

This may be a dumb question but I have to ask.
Is the MAF assembled correctly or backwards? I mean, with it in the car, does it spray twards the air filter or the throttlebody?

Found out what the problem was, seems like the MSD window switch in not getting enough voltage, and for that reason, only fuel was being added to the car, so that threw the 3 codes, will call MSD on Tues or if anybody knows how to fix this problem car dynoed 331/350 with 100 shot it dynoed 430/480. Happy with the numbers! Thanks guys for all the info, really did help, thanks a bunch!!!

I had a similar problem. Had to have mine sent in and converted to read the LS1 PCM tach signal. It cost me like $50. I guess it's random, some people have that problem, some don't.
