hot and cold start issue/cranks barely fires then runs fine
2000 v6 180K
The car sometimes hot, sometimes cold will fire right up. Other times it will crank and crank but not catch until the second or third try. In this situation it will catch and run like it's only firing on half (3) cylinders. Then the idle comes up and runs fine. It seems to run rich initially as I get some thick smoke out the tail pipe and it smells rich. Also the fast idle seems to stay up for some time. My MPG is only about 20 and I was expecting better.
Replaced all 3 02s, plugs, air filter, gas filter, and now ECT (two terminal sensor on passenger side of motor.
I have been trying to fix this annoying issue for a while now. I've seen lots of posts on ECT but am a bit confused. Is the ect the two terminal sensor or is it one of the other two single terminal sensors? I see one next to the sensor I replaced and another on the drivers side of the motor.
I read about some type of injector engine temp sensor. Is that one of the others i see in the manifold? The local parts stores only show the one I replaced.
All help would be appreciated.
