My car has been stalling on me lately. It used to be only after I get out of work and it's warm out but it's getting worse. It will stall as I am coming to a stop and push the clutch in, it will hesitate for a second or so then just stall out.

I have been throwing CEL 67 & 10 lately althought at this time I am not. They clear after a couple days. I was pointed to change my o2 sensor so I did and it's still stalling out. Could the IAT sensor cause it to stall if it's bad?

Car has JRSC, JR BTC, JR FMU, B&M FPR, Hondata IM gasket, DC header with leak, Stock cat, Thermal exhaust, AEM short ram, Walbro 255lph, new plugs, new rotor and cap, new 02 sensor..

Oh yeah while it was stalling out the other day I was watching the fuel pressure and while it was hesitating or stumbling it would drop to about 35psi and then stall out.

If anyone has any ideas it would be greatly appreciated since I am at my wits end on this..

 

It sounds like you have a fuel delivery problem. Start simple with a new fuel filter. If you have another fuel pressure regulator to swap out, try that. Lastly, I've heard of Walbros before, so that's something else to check out.

 

fuel delivery? you can get that stuff delivered! wow i am sick of driving to the gas station. think about it you waste gas driving there. this is great maybe i can buy a jdm nsx now!

 

Sorry I have also changed the fuel filter and changed back to the stock FPR and that didn't help either.
