97 Camry - engine problem, bad gasoline?

I bought this Camry about 2 weeks ago, and while I was driving the car I had the following problem a couple of times: I push on the gas pedal but the car does not accelerate. I tried to push on the brake, that didn't help, then after about 10-30 seconds the car does accelerate when I push on gas. When I got the car, the Check Engine light was on. I looked at the codes and it was something like: "Cylinder 2 misfired." I cleared the codes, the Check Engine light was gone for about a week, then it came back on, and now it's gone again (disappeared by itself). When I was buying the car, they told me that the light ws on because of the oxygen sensor (even though they had replaced it once or twice).

BTW, could this problem be caused by bad gasoline? I live in Iowa and we have a lot of 87 made with Ethanol - that's what I put in last time...

Thanks.

Sounds like a bad ignition coil or plug to me.

My Pontiac 6000 did something like that to me back in October. The cause was the oxygen sensor. The engine lost almost all of its power and was slowing down, so I floored it, and nothing happened and then suddenly, it kicked in and all of my power came back. I was just about ready to pull over.

Hmm, that's exactly what was happening to my car. I just wonder how can oxygen sensor cause smth like that? I thought it was a plug, too...

I don't know, but mine did. At the same time the engine lost power, the service engine light came on. We already knew it needed an oxygen sensor. When I managed to make it to school that day, the codes were the same, pointing towards the oxygen sensor running too lean. It only takes $30 and

Even though the check engine light went off, there is a good chance that there are trouble codes still stored in the memory. You should scan all of the codes whenever the check engine light comes on. The reason check engine light might turn itself off is if the indicated problem has 2 trip detection logic. If you are still getting the misfire codes, check the coils and plugs. If aftermarket coils or plugs are installed, try installing genuine Toyota parts.
