Sputtering.

[v8killar]

First off i'd like to say that i've done much searching, and alot of replacing already, and i'm still having this problem. About 2 days ago i was driving on the highway and my car starts sputtering then it threw a CEL. i get it home and listen and it sounds like it's starving for fuel. first thing i did was a boost leak test then I replaced the plugs and wires with Bpr6es gapped at the usual .028. changed the oil and filter (needed to anyway) as well as the air filter. Checked the MAP sensor and cleaned it and the little houseing it sits in, as well as drained my gas and added a new tank of 94 octane. The only thing that seems to make it run even remotely close to normal is when i unplug the MAF.

Anyone have any suggestions??

Yup, find out the cel code...

 

[v8killar]

the CEL was for an O2 sensor, would that make my car sputter?

 

[Epic904]

which o2 sensor, the front or back?

 

[v8killar]

rear o2

 

[v8killar]

nothing?

try replacing the front o2 anyway. the ecu reads that sensor to figure out how much fuel to add. or check for vacuum leaks.

Check to see if your injectors are working properly. I know it doesnt happen often but I have had experiences with injectors going bad and the car either decides to not run or run rough when it happens.

ok i checked the front o2 sensor as well and looked at the injectors. I went to turn the car on and my logger said i had these codes. p0110, p0300, p0105, p0304, p0100.

P0110.....Intake Air Temperature circuit.
P0300..... Multiple cylinder misfiring detected
P0105.....BARO Pressure circuit.
P0304..... Cylinder No.4 Misfire detected
P0100.....Volume Air Flow circuit

no one?

P0100, P0105, P0110 all sound like your MAF just took a crap on you.
