Alright so I got misfire on cyclinder 1 and 2. Then heated rear o2 sensor which means I need new ones. But the car runs mine. No hesitation at all! Or at least I cant feel it. What gives? I am going to drive it around tonight but take it easy. Hopefully I just need to change the o2 sensor then things should be good. It does have all tune-ups up to date with 82k on orginial engine. Might have to change the spark plugs if they are burnt up but they only have 15k on them and they are platniums.

 

Could be a bad coil or 2.

 

deff replace the O2 sensor, reset the ECU and go from there. Bad O2's have been known to throw random misfire codes aswell.

That is what I thought because the car does not really misfire. I dont feel it or anything. Yesterday I did a lot of city driving and it was fine.

I think 3 o2 sensors and reset ECU and it should be good like you are saying.

 

This is kind of off the O2 sensor subject but maybe someone would know what is causing my 0705 check engine code (EVAP Emission Control). This light keeps coming on and will not go away. I was told a possible solution was to tighten the gas cap of course or if it was possibly bad to replace it which is what I did. The engine light turns on and off whenever it feels like it. It's not pulling any other codes so I assume that all the major parts of the system are ok. Anyone know what else could be causing this?
