Hello, my name is***** is a common symptom caused by a clogged catalytic converter. You can completely remove front oxygen sensor from exhaust to relieve pressure, if that allows engine to run better you know the converter is clogged. Let me know if you have more questions or if there is anything else I can do to help. Thanks.

Hello now I can't get car to start at all it just cranks and smells like raw fuel before when I did have it running it smelled like it was running rich and I had to keep my foot to the floor to keep it going do u think a crankshaft position sensor would cause this? But I have no codes. When using a scanner thanks again

I still think problem is likely clogged converter. Check for spark, if spark is good then remove front oxygen sensor to do previously mentioned test. Let me know how it goes or if you have more questions, thanks.
