NoLeftTurn

I am having problem with my car running rough. Its a stock b16 with gsr cams. I have a walboro 255 with id1000's. Running a b16 turbo basemap sent from a tuner. My vac gauge reads -9 psi, my wideband reads lean 21.8, but im running an open downpipe until I get my exhaust back. I have check the compression 200,190,200,200. At first I thought it was my injectors because when I d/c 1 and 4, the engine would die but when i d/c 2,3 no change. Pulled spark plugs and there is gas on top of it. Any suggestions would help a bunch.

what map sensor you got. sounds like the car needs a good tune

its a gm 3 bar. I got a basemap from a tuner for now. Ill get a tune once I get this fixed. I dont know what else could affect my vac reading.

where are you getting you vac source from going to the map sensor

Get a good tune. Should fix everything.
I'm reading -20 on my vac gauge at idle.
U might have a big vacuum leak that was fixed by adding fuel to make it idle.

If ur reading -9. There's prob the issue

vacuum block with no t's

Im reading vacuum off of my boost gauge. Maybe I should get check if off the vacuum block.

what is the rpm at idle

NoLeftTurn

roughly around 1000

If it's running at 21.8 air/fuel ratio at idle no wonder the idle is crap, add some fuel to bring it down to 14.7-15.0 air/fuel ratio

I think it might be the tune. Ill post datalog off hondata tomorrow.
