supra wont rev past 3000rpm

[dee242]

So mods are 3in exhaust boost controller on stock boost 550cc and LEX AFM and I just recently replaced AFM sensor. This started as I boosted down the street it started to stumble and what not now wont rev pass 3k I have no vac leaks and have a video of what the car is doing and code it has below https://www.youtube.com/watch?v=5v3fWVPgdZg&list=UUFxsC5qqvsssLWEbGveyiTw

so what code do you perceive that to be?

 

[dee242]

31?

Exactly what it's supposed to do when the afm signal is bad.

so what code do you perceive that to be?

Nicely done...

 

[dee242]

So what exactly would that be just a messed up conection or so

 

[sheedy126]

open or short circuit in air flow meter signal.

could be airflow meter circuit, air flow meter, or ecu. pulled this straight from the TSRM.

you said it started when you were boosting down the street and started to stumble. do you have a boost leak/intercooler coupler that is off?

was it running good at some point after you installed the lexus/550's?

 

[hvyman]

Generally when you have a boost leak a 34 will be stored.

His problem is most likely the afm but possibly the wiring as well.

 

[dee242]

It was running fine prior and ok will start there

 

[dee242]

got it was a cut wire
