- 2010 Explorer XLT 4.0
Hi Guys
Bought a 2010 Explorer XLT 4.0 a few months ago, currently 65 k miles. As far as I know
all stock (nothing obvious anyway) so far hadn't had any problems.
So, about a week ago I accelerate away from a stop sign and my engine stutters a bit
pull over and she is idling rough. I sit in a parking lot for a few minutes and then everything
is fine. She runs good for a couple of days, the stutters again, rough idle...but at speed
runs fine. I stop a couple of days ago at the local auto store and get my codes read.
Sorry, check engine light didn't come on until about the second incident.
CODES:
P0304 Excess emissions level of misfire detected cyl 4
P0204 injector circuit/ open cyl 4
P0300 random misfires detected
P0305 cyl 5 misfire detected
P0306 cyl 6 misfire detected
P2198 02 sensor signal biased/stuck rich - bank 2 sensor 1
P0175 fuel system too rich -cyl bank 2
I looked under the hood and didnt see anything obvious, plugs, wires, coil all seemed
connected nothing loose. I am somewhat mechanical...I can change my oil, plugs etc..
I CANNOT rebuild an engine....
I do have a tight budget. I thought maybe I had gotten some bad gas so I ran a can
of GUMOUT injector cleaner and a tank full of gas from another store.
My mileage has dropped to 8 mpg from about 16 with mixed driving.
The stutter is still intermittent. I can go several miles with no issue, but then its back.
Seems to be worse taking off from a dead stop, or accelerating in traffic.
ETA: I will get a strong smell of gas on occasion at start up
The CEL is on and will occasionally flash for a few seconds then stop. Where do I start? Is there maybe one thing causing all the issues. I have read around on this forum and see
fixes from plugs to new engine...Just seeing if I can get pushed or shoved into the right
cheapest fix. Hopefully something I can do. Thanks in advance guys.
