I've had my N/A for about 4 yrs now, and 6-8 months on my "JDM" engine. This is the first time i've ever had a misfire at idle while the engine is at normal operating temp. While it's in drive ,it does it more, neutral or park not as much, but it still does it. No engine codes, TPS adjusted to specs. and new plugs , wires , distributor cap---prevenative maint.---. New vacuum lines and no leaks says the vacuum gauge......but you know what - its still there.
Any ideas or suggestions ?
