1.8L Dual carb question
I just bought a 1985 lude, 1.8L dual carb..
I dont have a manual for this car yet so I am hoping someone can yep me out. The cat-converter is fooked on this thing, it's completly plugged up. My question is: Is there an O2 sensor hooked up to the cat? I'm planning on just getting rid of it completly, any issues with this? |
Re: 1.8L Dual carb question
You probably have an O2 sensor, but it would be before the cat, so you
shouldn't have any "computer" problems.

Feedback carburetors use an O2 sensor, and have a bundle of wires and a bewildering array of vacuum hoses in most cases. Or it may be an older "mix it and burn it" carburetor that is running too rich. The O2 sensor is undoubtedly long dead if you have one, and the cat was probably melted by an over-rich mixture. Removing the cat won't change much except for clearing the blockage, but is a violation of US clean air laws. (Assuming you are in the US...) if you are caught and prosecuted, the penalties are positively medieval - tens of thousands of dollars (no fooling!) and possible prison time. You should be able to get a replacement cat for about $100 installed. Mike |

Re: 1.8L Dual carb question
That sounds like a very similar setup to my 89 YJ, it has a brutal computer
controlled carb that is a peice o ... There are a whack of vaccum lines, so im assuming it is the "tweaked" version. Thanks for the input, looking forward to playing with this little "beater" I'm in Alberta we have no emmisions testing on any vehicle.

Re: 1.8L Dual carb question
The O2 sensor is mounted on the exhaust manifold. It looks like a spark
plug with a wire on top running toward the radiator. I believe that there is a free flow cat. available on Ebay, Search 85 prelude or 87 prelude. |
