Hello everyone second post here I have a 95 ex with a d16z6 no mods, I'm just trying to get her to run ok. But I've noticed that my oil level keeps rising and my oil is getting diluted with gas. My plugs are also fouled out which I plan changing today. Getting code 43 for fuel system. I thought my timing was off but seems to be perfect, so I'm sure that's not the issue, Now I check my injectors for pulse and I'm getting pulse in all of them. I also checked my compression and getting 150-160 in each cylinder, so I'm sure my rings are ok. I also know it's not coolant because I've had a blown head before, and coolant level is still good. Just wanted to see if anyone had had this issue or can point me in the right direction on what and how to test. Lastly I was thinking maybe a fuel injector is staying open allowing too much gas to enter. Thanks again hope we can get this resolved

 

Just put new plugs and fouled after running in idle.

 

Code 43 is fuel system supply.

You're obviously running rich and the engine is receiving too much fuel, now to trace down what is causing it.

 

Yup my TPS seems to be getting upto 4.5 when fully opened, changed out MAP with no avail. Fuel injectors are pulsing fine. What other tests should I perform?

 

O2 sensor, fuel pressure etc.

Are the plugs fouling the same amount or is it one particular cylinder that is fouling?

 

All plugs the same black as hell. Recently changed out o2 sensor. And had a resonator but it cracked so straight piped it.

 

fuel filter? fpr?
