Hey guys, my wifes 2006 Focus had a hit and run the other day and now we are having problems with it. It just got backed into and just made a small dent in the trunk(though person who saw it happen said it was enough force to move the vehicle)

On the way driving home it died, and I managed to limp it home. First thought it was bad gas, so siphoned gas out and tried pure gas(no ethanol) that didnt work. Also replaced fuel filter, and I can hear the fuel pump come on so i think that is ok.

I can start the car and it will idle for a few seconds and die, and I can consistently do that, it doesnt do it once and then not start again. I can also start it and pedal the gas a little, have it reved up to 3000 rpms and it will run like that for maybe 15 seconds and then it tries to stall out.

My dad drove it and had the check engine light come on and got a P2195 and P2196 code to show, but after resetting it the light doesnt come back on.

I don't know where to go from here, not sure if I need to be replacing o2 sensors, and don't want to invest in them if thats not the problem.

Thanks in advance for any help
Todd

This probably isn't the solution but I'm curious if the fuel cut off switch was switched. Would it cause problems like this? Or would it simply not run?

Well I read about, it says that in an accident it could bump that switch. If so you just need to hit the reset button, so I did. No real difference.

My focus is showing the P2195 code for the O2 sensor and a P0171 for sytem lean sensor1. It was showing one for the EGR, but i cleaned it and it is working for now. Any guess on whats going on?

Whats the EGR? I got it work to what seems to be fine now. Not sure if its a combination of cleaning the mass air flow sensor or taking the negative terminal off the battery for a while. I did the battery earlier and it didnt seem to do anything.

Usually it takes a couple cycles for the code to show back up. Hope yours stays off. I went to get parts for mine today. Took it to get it diagnosed and it took the guy 2min. to locate a vacuum leak on the back of the motor behind/below the throttlebody. I gotta fine those at the dealer tomorrow and hopefully i can have it purring once again!
