Hey everyone I have a 1991 Honda Civic Std or DX model, I bought it with an engine swap with a SOHC 1.6L ZC engine. I brought it for an e-test and it failed here are the numbers

40KM/H
HC ppm 110 Fail
CO % 0.19
NO ppm 3686 !!!!!! Fail

The idel rpm is 1124

More info to come! Any info can help!

 

Aftermarket "cat" (e-bay flow thru unit) perhaps?

Best not to pay for any car you're considering buyinguntil you've seen it really can pass the smog check.

 

Yeah I havent checked the car but I will but, I dont think thats what it is, I should of did more looking into, but it was a perfect condition car mint and I got it for 1400Canadian.

Alright here is the whole E-Test sheet.

I was talking to the mechanic, calls himself the "Honda Expert" and he has a good rep from a lot of people I know. He said that the wireing was sliced and diced for the engine swap, my TPS sensor is tampered with, possibly a new ECU (but I know its the right one and he agreed after I explained). Could it be that the wireing is all messed up? He said its gona be a costly job. I can agree myself on the wireing cause its a 1991 Honda Civic Standard model, and I heard you need a whole new wireing harness to fit a 1.6L ZC engine. I think the guy was just lazy who did the swap, any info would be GREAT!

 

I'd drop the cat first and see if it at least has some potentially active material inside. If it has an active CEL and runs without the CEL on it may be in pretty good shape as far as the controls go.
