Hello From London

Hi Guys ,

I have had my year 2000 s14a 200sx since 2005 and have been a member on SXOC since 2004.

Until recently I have had zero problems with it. It's a UK spec SR20DET.

I have done numerous mods on the car.

Stainless exhaust manifold back.. including HKS Silent
T28R TURBO
HKS boost controller
FMIC
REMAP
255L fuel pump
Cold plugs
The list goes on.. all work done mainly by me!

Recently however I have been experiencing an idling problem. When the car warms up the revs drop to about 600rpm. When I am coasting along and then try and come on boost the car really hesitates. If I keep feathering the throttle then it comes on boost fine and boosts all the way through.

Anyway.. hoping for some help here.. pulling my hair out!
