I started my pathy today and it was idling fine. I let it warm up for 10mins. When I tried to back it out, it stalled. I would restart right away, I had to wait for a few minutes.

Then, I started it again, this time I had to set on the gas while turning the key. It started, belching out a cloud of dark smoke. It idled fine until I tried to back out, then it stalled. I started it again, tried to move it forward into my parking spot - stalled.


Anyone know what this might be? I thought I could smell gas/very rich exhaust near the back end. Could it be the fuel pump? Any help would be appreciated.

if it runs ok when engine is cold and it gets worse when it is warm, it is oxygen sensor. oxygen sensors start to operate after it reaches a treshold temperature. also if it stall it can be due to airflowmeter sensor. when i remove mine it idles correct but cant rev. it stalls.
