Hi Guys,
I'm new in this forum and perhaps sifu sifu here can give me some advise on my issue. I owned an evo 7.5 gta and lately getting a very strange problem which is the RPM drop tremendously to 500 and bounce back when i'm pushed and released the gas while i'm driving. The event only happend when i push released the gas at 2500-2800 rpm especially when stopping and moving between speed bump and up hill. The issue happened right after replace the faulty OS2 sensor. No faulty code, no error was detected by using the Autoland Scan device. Tried turn off BOV, replaced throttle body, MAF sensor and even install the HKS EiDS (Electronic Idle Stabilizer) is doesn't help at all result the same. Any idea? What the possible cause of this issue?
Spec as the following:
Stock ECU
Evo8 downpipe
HKS Fliter
HKS BOV
Greddy Boost Controller
Apexi Timer and Boost Meeter
Pivot Speed Limiter
RallyArt Exhaust
