hi, basically as the title says. .

If I let the engine cool down and crank it after a while, the car will bog out. On high rpms it smells/runs rich . . . . is this due to the o2 sensor being bad? I no longer have a cat, (2.5 all the way back). If not the o2 sensor, any other suggestions?

Thanks in advance

thats weird....im having similar problems....if i start my car up and let it idle and shut it off, then try to start it back up a second later, it will have problems turning over.....dont know whats up with that....

 

btw im running a jdm b18c-r with a p28 chipped ECU....thinkin im like u and runnin too rich...i had a 02 sensor code thrown and im thinkin that could be it too...were probably on the same boat..

 

hmm maybe so , but my bogging is on the first crank in the morning, our after letting it cool off and only on the first crank . . after a second or two of giving a little gas, it goes away .. weird. Anyone else?

 

I had a similar problem. The easiest way to tell if its your o2 sensor is to disconect it and go for a drive. The car will run off pre-determined maps, and they aren't bad at all. You will get a check-engine light, but at least you will know that the o2 sensor is bad if you disconnect it and it stops bogging.
