Howdy,
I am about ready to go crazy trying to figure out what is wrong with my 1992 ES 300. Maybe someone with more knowledge than I have (not gonna be hard to find!!) can help me out here. Here is the story....
About a week ago the car starts to develop a really rough idle at times. Well, when it starts stumbling really bad, it smokes like crazy. But after you open it up a little, it quits doing it. Next time you might stop, it might be just fine.......no smoke, no rough idle. So, the check engine light comes on and I take it to Autozone. They say that it is the rear O2 sensor, and it needs replaced. So I buy one from them, a Bosch brand (universal), and install it in the rear manifold by the firewall.
It clears nothing up, and is smoking ALL the time, but the check engine light isn't coming back on though. It only starts to smoke really bad, the longer you run it. And you can smell fuel everywhere, inside the car, behind car......
So, I go back and they tell me it could be the fuel filter..........lol, I am thinking "yeah, that's what it needs is MORE fuel!!!" So, I put a new one on there. Doesn't help (as suspected).
So then, I go talk to a mechanic......and he says to check the coolant temp. sensor located by the thermostat. I might replace that today, but I am not driving the car, as I don't want to damage the engine with it flooding so bad.
Anyone have any ideas on this one? I would appreciate any help you may give me. :)
