Data logger video Whats Wrong

[2GFWDbeast]

I posted this video of what my data logger is telling me. im using Palm'nstein on a m505. sorry for the sideways shot.

My car started to run like complete crap out of no where 2 days ago. Dying at idle, while driving it bogs and reads super rich. When i turn the car on it will read rich then it will read perfect 14.7 then goes to super lean and the rpm's drop and then car dies unless i give it gas.

I replaced the spark plugs with new ngk br8es with a gap of .030

I also replaced the maf thinking maybe it was that to. I do not have any boost leaks or vaccum leaks. My throttle body has the fiav mod done to it. I still have the iac hooked up tho. This throttle body set up has been like this for a while now.

2 months ago a piston ring broke, and cause a ton of oil to go everywhere. There was at least 3/4 quart of oil in the intake manifold that the shop pour out. Everything was cleaned but the intercooler and ic piping.

Could oil still be getting sucked threw the piping and causing the tb to be caked in oil again?

car is running on E85 and is tuned for it.

I would say for sure to remove al the I.c piping and check it all out along with throttle body make sure thers no oil in there and possibly replace the 02 sensor. As far as running e85 I have no clue about that. If ther is oil in the I.c piping chances r there is more n the I.c its self so you might wanna clean tha out as well

Allso I see you said you used br8es plugs is that a typo because you should be running brp8es or brp7es depending on you mods

You can use both but you should use br8es. brp8es have a protuded plug which causes misfire. Every person i know that run's high boost on E85 use the br8es with no problems. Iv also asked high performance shops like ams and strictly modified Who both have the fastest evo's and gsx's around the nation they all recommend br8es or higher depending on how highly modified your car is and the amount of boost your running.

Huh I've never heard of using the br8es or the the brp8es causes misfire is this just a e85 thing or are they good for 93 octane pump gas as well?

ya thats what i said

so just so I'm clear your saying the partuid plugs cause misfire, can the br8es plugs be used on 93 octan pump or only e85?

Yes and Yes depending on how heavily modified your car is, and the amount of boost. stock should use the 6's, slightly modified use the 7's, heavily modified 8's and up

Ok now that that's behind us, did you check the I.c piping for and t.b for oil?

no i actually figured out the problem i had a bad tps

 

[mheidemanjr]

Allso I can't get the video to play but by looking at the pic I can see your 02 volts ar way off and so is the isc if you are at idel. Airflow looks realy high to for idel. I would try swaping out the o2 sensor

O sweet problem solved. Would still say check the I.c piping for oil to save your self problems in the future.
