Chasing issues. B18B1 EG Hatch
For some time now, basically when I first got my 1994 hatchback with a 96 LS swap motor in it.
Fixed all odds and ends, got her reliable and roadworthy, but still to this day I’m chasing down a few issues and could use some extra brains to help me resolve this.
Problem: Slight misfire at idle and when driving, nothing major, all cylinders have spark, fuel and compresson (although I have not yet done a check). Also, it’s been running extremely rich which I believe relates to this issue.
Stuff done: Headgasket, Valve seals & valve job (Cleaned, replaced some, re lapped, etc.) Walbro 255 fuel pump, AEM Fuel rail and regulator, 6an fuel line, msd coil and cap setup, adjustable cam gears, and most other available bolt-ons.
My engine if I’m correct, should run around 47ish psi fuel pressure at idle. When I set my pressure at that, I can tell the car is struggling for fuel. I am curRently running it a 52-55psi and it seems to like that more, but it seems way too high for idle pressure. And I feel like whatever my issue is here, that high pressure might influence how my car is running now.
Any input or advice to where I should look next would be greatly appreciated. I’ve gone through almost everything I can think of and I’m starting to get really fustrated chasing this down.
