Hey guys,

I'm having a few issues with the car. I honestly haven't run into a check engine light since I got my motor mount replaced years ago, but I guess it's that time when something has to get fixed again!

The Check Engine light is throwing me these codes:

P0300 Random Misfire
P0130 02 Sensor Circ 1
P0150 02 Sensor Circ 2
P0305 Cyl 5 Misfire
P0306 Cyl 6 Misfire
P0307 Cyl 7 Misfire
P0455 Evap System Leak gross leak no flow

Replacing the 02 sensors won't be a prob. Any ideas what the misfires could be? Spark plugs? motor mounts? tranny mount? Although, the misfires rarely occur in the car.

Another thing that's really worrying me is the Evaporation System leak? Anyone know anything about it?

And lastly, I keep feeling vibrations only when I'm at a stop and is esp felt under my seat? Any idea what that could be?

Any help will be appreciated,

Thanks in advance!

The misfires are alll on one bank and I bet that the bad O2 sensors are causing the rest of the codes. Replace the sensors and then clear the codes and run the car again and see if the codes come up again. Good luck

Thank you for your advice. I'll def. replace the 02 sensors first and see what happens!

would be the first place to start on the evap issue,then examine all lines to the cc canister.Then check the Purge valve lines and operation. Clean it while inspecting.
Surprised you don't have misfire codes on pass side bank 1 since the pre cat o2 is gone there also.
Both sensors are under 2 bills total
Going to have those solved before you can track down the Vibe

Awesome, thank you! Will let you guys know the results when I change the 02 sensors.

I actually changed my gas cap a few years ago so it's fairly new!
