Rb20

[GHO57]

hello everyone..ive got a red top rb20 in good condition..no mods..it did have a boost controller and bov but ive taken that off now so its full stock, bar a pod...sometimes when i start the car up..its idles fine but then the idle goes up and down..sounds like its about to die or something..the boost gauge is -19, -20 psi on normal idle..but then it goes to around -16psi..on idle and then it sounds like its about to die..wat maybe wrong with it?..any help will be much appreciated..thanks

clean out the acc valve.

also look at the throttle body butterfly positioning - may be starving it for air hance the splutter.

Check all your vacuum lines, sounds loike you may have left one off or split one when you removed the bov and boost controller
