Finished my b16 swap ran awesome for about 250 miles. I now have a super rich fuel problem. I have an apex AFR guage hooked up, reads 10.0:1 A/F ratio or less. O2 voltage is 1.3-2.0. It might be a loose ground? Any Idea's at all? its a stock b16 with a p28 spec c ecu. This is driving me [freak]ing up the wall. Plugs are perfect runs on 4. Igintion timimg is 16 deg BTDC +/- 2 deg. All in spec. Engine sounds fine cracks vtec nice and hard. All the fluids are full no moisture on Oil cap. No oil leaks all the fun ****. It runs right intermitently, and sometimes the tach and speedo jump. Could i just have a loose connection somewhere?

morning up. someone shed some light please?

 

Hows the fuel pressure look?

Might have a bad diaphram in the fuel pressure regulator thats allowing the engine to suck fuel in from there.

Not likly to cause only intermittent problems though.

 

fuel pressure is good. i like my fuel pressure guage, its about 30-35, high flow pump. and problem fixed. tell the mod's to close the thread i had a loose ground.

 

Out of curiosity, which ground happened to be loose?

 

my water jacket ground, where your o2 maf and fuel system ground to. only problem with how honda wire's motors and cars, no redundant grounding, easy to find problems, but when you have a problem good luck driving it. im gad we dont play with toyota's where there's a ground every 3 inches on the return side of circuits.
