hey guys im having some serious missing issues....around 7-8psi i get this serious missing then all of a sudden its fine...this happens in every gear... i get the feeling that fuel isnt coming properly...its odd...any advice? im thinking of getting a supra fuel pump maybe my stock ones done for...or could it be the injectors? any other possible reason for this issue? cuz ive been fixing my car ever since i bought it everything is perfectly fine except for this missing issue? i always thought it was cuz i was running 13psi without the pfc but now im running stock boost and the issues still there...thanks...

 

anybody? its the one prob i cant seem to solve...sigh

 

What are your mods? 13psi without a pfc is not good... but you could just be running rich perhaps.

Dennis,

 

yeah i was running 13psi on the stock ecu so i figured it was the boost cut rather than the missing...but now even at stock boost i get the missing issue so its really confusing me...its something fuel related just dont knw what...

 

ok update...chcked the fuel filter was a lil dirty cleaned it out but still have the same prob...any ideas guys im completly stumped here!

 

Do you get a check engine light when it stutters?

 

what are your mods? 13 psi def isnt safe on the stock computer. aside from running out of fuel from too many mods, or fuel cut from too much boost, it could be ignition related. coils, plugs, wires etc.

 

check your fuel pump, sounds like its going bad....

 

yeah thats what im HOPING it is...are these symptoms common when runnin a weak fp?

dude im running 10psi i tried 13psi at the start ages ago when i didnt know better.but yeah im gonna get the fuel pump first if thats not the issue then my next area of focus is gonna be ignition...i just hope the fuel pump solves the prob...
jdm...no check engine light


im gonna use the supra fp to see if that fixes the issue...fingers crossed
