2000 WRX wagon with a new short ram intake and an engine light to go with it. Lean mixture on it and i know it's from the intake but i am trying to find a cheap solution for this, i don't want to try and retune the ECu but i think that if i put in a new fuel pump, walbro probably, but i'm not sure if it's the right solution.

2000 WRX?

Which type of air sensor, and did you move it?

2000 WRX?

Hard to believe that unless you did a gray import or engine swap.

as said before, moving the air sensor should get rid of the CEL.

However, if want it to stop running lean, off the top of my head, will require ECU tuning. I don't see how changing the fuel pump to a higher flow one is going to do much if the ECU doesn't know how to use it?

Also, I wouldn't think the intake itself would max out the current fuel pump.....so it comes back again to ECU tuning.

higher fuel pressure perhaps?

It could be from the sensor location buz its some knock off intake, but i dont have the tools to retune the ECU and the know how to increase fuel pressure. Not really a WRX guy, just helping a friend with it.
