Rb26 stalling

[slammedvert]

For about the past month or two my car has been stalling out while driving on highway or road where I'm maintaining constant speed. The car remains on but I lose all power and starts dropping rpms so I have to pull over turn the car back on and wait till it decides to start working again usually only takes min or two. Then I went to go drive it yesterday and started it and it was idling fine then would just die did this three times before I was able to drive it. I'm just trying to get the car running good again before I take it to another show.
I just put in yellow jacket coilpacks, spark plugs I have a power fc I installed back in September with stock turbos.

Thanks, zack

Unfortunately, we need more information from you when this is happening. Do you have a fuel pressure gauge installed to let us know if the fuel pump is loosing out? Do you know if it is getting spark or fuel when this is happening? This could be a multitude of things and for us to give you an idea, you will be just throwing parts at it. It COULD be an ecu, ecu relay, fuel pump, fuel pump relay, CAS, ignitor, bad ecu ground, etc etc etc etc.........

If I were you when this is happening, try swapping out to the stock ecu and see if it immediately fires up, could be a power fc issue, you never know.

I had a little bit of time yesterday so I worked on it a little. My car goes 20.0 when it loses power so tried checking the fuel components. First I just cleaned my mafs since that easy enough. Next was checking my injectors and #1 injector clip is broken so it just slides off so need to find a new clip for that and also the fuel filter had gas sitting on top of it so need to get a smaller hose for that. Also the hose going to my blow off valve had a small crack in it so going to get a new hose tomorrow. I'm hoping from just fixing these small things it helps, I will find out tomorrow and let you know.

sounds like 1 of your MAFs is on it's way out. are you running PFC? If so, you can see it on your hand controller in the etc. menu. the MAF indicator will go black causing a stall.

try getting some known good replacement MAFs. I have NEVER had good luck cleaning them, it doesn't seem to work at all.

Ok I'll try that out, should I just stay with stock mafs or go to 300zx mafs. I'm guessing would need more tuning also have to deal with wiring the plugs up?

[gawdzilla]

yes you will need to rewire and yes you will need to retune if you go to z32 mafs
