Hi guys.. a little question here..

can u tell me if my Fuel Pressure Regulator id bad??

i make that question because if the engine is running and i disconect the vaccum hose attached to it, nothings happen.. the engine still running and nothing change.. is it bad?

 

Why are you messing with the FPR?

 

because i hav a very serious problem with my idle and i dont know what more to do... :S i have replaced EACV, FITV, TPS, my ecu is new, ECT, clean Throttle body, good PCV, no vaccum leaks and i still getting very very low idle speed and my car is eating a lot a lot!! of fuel.. i do a video about the idle, look it

Specifically "Check the timing with a timing light"? I don't see where you mentioned that you did that. Replacing random parts hoping to fix the issue is not smart and very expensive.

 

why don't you adjust and turn your idle screw up on the T/B.

 

yes i do the timing, and the idle screw, if u loose it the idle dont go up, ..

 

Bleed all the air out of the cooling system.

 

i already do that, but my question is, why the low idle only happen when the engine warm up, if it cold and A/C is turn off it run very nice.. but when it gen warm the low idle appear

 

u sure you used a meter on the TPS sensor to properly calibrate it?

 

Yes!! i used a a multimeter, 0.5 throttle close and 4.8 WOT, it is ok..other thing i say adove is that my idle screw dont work, if you unscrew it nothing happen with my idle :S

 

maybe Ron will chime in and help out on this one.
