My car almost stalled on me numerous times today. A couple of times where it actually stalled. I had to rev it up to prevent it from stalling all the way. One time where it is stalling, I popped it to neutral, and the RPM went from below 500 to around 1500. All this is during idle at a light. I've been getting some really low idle RPM's lately, like 5-600, when it is on gear (on 'D', I'm AT). If I pop it outta gear (park or neutral), the RPM's would jump to more comfortable 7-900 RPM. I was starting to think it's because of all this FL heat, but it happened again at night time where's it is cooler.

The fuel filter has been changed during the turbo install around 6,000 miles ago. Plugs and wires have been changed less than 2000 miles ago. I'm beggining to think it's this HRC billet FPR. Maybe the fuel pressure acts up or something. I pop the hood when it is at park, and the thing is pretty steady at 55 psi. I'm not sure if it fluctuates when the engine is under load, in gear while idling, i've been too lazy to put up the FP gauge in the windshield. The SFMU goes in tommorow, we'll see if that will fix it.

Check you TB, if its really dirty, clean it. Could also be your IAC motor on the TB going bad...doesn't seem like fuel pressure related IMO..

I was also thinking about air delivery too. I cleaned the TB like around 8000 miles before the install. I'll check to see it it's the IAC tommorow.

yah check your iac motor to see if its clean, and the resistence is within specs..same goes for your tps check that out...with the s-fmu installed you better put the gauge on the glass to make sure its within specs. trust me you rather put that gauge on your glass to make sure its all good, or you might regret it when you got to rebuild due to a fuel issue...its on you dude... later
