Earlier today on my way home I noticed an odd sound comming from my car. It sounded like a low frequency rattling or bogging noise. I turned off everything to listen but it easied itself away as I slowed down the car.

JUst went outside to start my car to leave again, and now it's a more definitive choking noise and it lightly shakes my car. I shut it off to try and start it again, hoping it was just a cold start.

Needless to say it did it again, and this time giving me a check engine light. I shut it off to pop the hood and make sure nothing was out of place (since I recently had it at Lindsey Acura for servicing). EVerything was fine and I tried to start it again.

Engine light again and ATTS light this time.

Figure the ATTS light is only comming on because the ECU can't find it with the engine code going on.

But where can I do the engine code testing in a 5th gen prelude? And does anyone know the codes or know of a manual online?

Any other opinions to the problem would be greatly appreciated. I'm not about to drive her until I have some idea of whats going on.

how to jump it.

 

Thank you! Now to just go check the code

 

1 short blink

Primary Heated Oxygen Circuit

* High/Low Signal

Should I take it somewhere? I'm not sure enough of myself to screw with my 02 sensor.

Advice?

 

It's pretty easy to change the o2 sensor. I have a primary & a secondary for sale if you're interested.

Also, even if you do have the dealer or someone change it for you, I wouldn't buy it from the dealer, they charge like $350 for one!

 

I acutally took it into a dealership I frequent. They pulled the codes and found a few.

Stored:
Vtec
EVAP

Recent:
Missfire

Oddly enough, no o2 sensor code.

THey suggested the missfire might have been from changing my gas brand? 0.o

The bogging completely stopped though. So... any suggestions, should I be concerned about anything in particular?
