euro trash

Just had my car inspected here in PA and was told it will fail. The safety went through ok but they took a look under my car and said don't bother with the emissions test, u will fail.

I have a 83 euro that the previous owner put on devek headers, cross over and then 2 straight pipes back to a pumpkin-located aftermarket muffler.

The inspection guy told me today my O2 sensor was missing or not hooked up and that alone is killing my performance and gas millage. Not sure if euros came with cats and an 02 sensor or this or some were added on some cars when US federalized.

So my Pennsylvania options are:
1. my would car be exempt from emissions if my car is under 5k miles of usage in 1 year, problem is my speedo and odo don't work and he can't verify the millage since speedo/odo has been broken since purchase, matter of fact last year's sticker shows the same miles as currently on speedo. Also would have to wait for July of this year since new owners need to have the car for 1 year for this exemption. And, I don't have the ***** to fix an odometer by the looks of the tiny parts.

2. add cats and O2 sensor then since car is over 25 years it would instantly pass a visual inspection and not require the **** probe of a test on emissions. Problem is i would rather not spend the money and chop the exhaust up for cats. Funny thing is a unknown garage ran last year's test and it passed on a visual of cats and o2 sensor. So someone greased a palm, because i can see these headers and pipes have been on for awhile.

Since I've had the car the speedo worked once, just magically came on one day WITHOUT odometer moving (suspect gear problem), and hasn't done squat since.

So my questions are

-- how big of a deal is the O2 sensor, the guy claimed that without one, you are killing performance and gas millage, my mpg is poor so willing to fix that if renners agree it is important.

-- And also, can I buy a new/used speedo, or send it to someone to repair it. Then just wait until July to retest, but drive around avoiding police tickets.

Sorry about the novel, thanks for any suggestions...

Do '83 4.7 CIS 300hp euro cars have 02 sensors? cats? Wouldn't the lambda feedback version be CIS-E?

BRB-83-911SC

My euro came from PA, no cats, but was registered there as historical. Is that an option?

Get a PA Classic Car plate. Mechanical inspection yearly and NO emissions inspection. Car must be over 15 years old. And no yearly cost for plate.
Antique plate is also available over 25 years but I don't know particulars.

The odo gear is a lot easier than you think.
Dwayne's Garage has an awesome writeup on it. Very clear, lots and lots of pictures. Takes you through it step by step.
Roger has gears that are drop in. Dwayne's writeup talks about having to remove molding flash. The gear I got from Roger didn't need any of that. Worked perfectly as it arrived.

the Euro does not support a connection for an O2 sensor,
the cars brought in had a bung welded onto the header pipe then an O2 sensor was screwed in so it looks the part but the wires dont have any place to connect at the computer

Antiqued mine last year for the 25 year mark. 75$ for life, no inspections, emissions.

Requirement was car to be stock from show room. Of course, mine wasn't, but a few snips copy/paste pictures of a car similar to mine and it suddenly was! The only requirements are to drive the car seldom. Car show, parades, or a day or two a week. ----not to be used as daily transportation.

Fits the bill for me. My car would never pass emissions.

Live in PA too, we are practically neighbors Eurotrash(name?),
no inspection needed.

Of course adding a feedback such as an O2 sensor will improve gas mileage/performance since AF mixture can be compensated for as fuel components age. I thought they only used K-Jet on 78 and 79? If that Euro motor is running K-Jet then there is no way to add feedback loop to it since it's almost all mechanical. There was KE-Jet which came on California cars and certain other ones i'm sure.

With Euro emissions standards lagging behind USA's back in the day, i can't imagine any Euro would use KE-Jet or K-lambda as some call it.

I got my old '80 Euro to pass smog here in California by buying an old $50 928 catalytic converter off Craigslist and a fuel restrictor (to keep you from putting leaded gasoline in it, LOL) and putting them on. It ran crazy rich at idle, but luckily the State of California doesn't mandate idle emissions, only dyno emissions at 15 & 25 mph. The smog tech stuck a mirror under the car, saw it had a cat, and passed the car. Didn't notice the O2 sensor wires going to nowhere.

Also, fortunately, 1980 was the last year before they went to 17 digit standardized VINs, so they had no automatic way to tell that the car was an import. DMV didn't notice (or care) that the speedometer & odometer were in kilometers (or that the dashboard was in German). I believe the parts vendors also sell replacement USA emission underhood and door stickers for repaint jobs as well...

Lotta dumb smog techs and DMV inspectors out there... Just sayin'.

The Euro 928s from 1980 - 1983 used CIS K-Jetronic fuel injection and there is no lambda control, thus nothing for an O2 sensor to plug into.

My 1979 928 is a US model. It came with the CIS K-Jetronic fuel injection sytem. It does have a catalytic converter and no O2 sensor. As long as the CIS is functioning properly I easily pass emissions testing - IM240 here in AZ, includes rolling loaded test at verious speeds, accelerating and decelerating.

To properly measure the CO% (air/fuel mixture), the measurement must be taken pre-catylitic converter. My shop installed an inspection bung pre-cat where the sniffer probe is inserted. The air fuel ratio adjustment is very sensitive so using the CO% meter is the best method.

I recently saw a 1980 Euro that was federalized, it had all the air-pump installed and cats installed ... it didn't have an O2 sensor.

The 1984 - 1986 Euro models had LH fuel injection and EZF spark systems. They did not have catalytic converters and used a non-lambda air/fuel mixture set at the MAF sensor. The Euro LH control module is the same base circuit board but the components for lambda control are not installed, the ROM code is different, and the CPU is a lower frequency than the US lambda controled model.

Federalization of the 1984 - 1986 Euro models often involved installing the air pump and a separate lambda control computer that would change the water temperature reading to the LH injection module, thus "fooling it" into making the air/fuel mixure more rich when told the engine was cold.

I also have an '83 euroS, with HISTORIC plates, $44 for the plates-$0 to renew and NO INSPECTION--BUT-- the car has to be 25-Yrs old and stock.

If the historic plates thing doesn't work, and you're *really* determined.. you could go for something like this:

A few people here have removed Federalisation stuff from K-jet cars.. Jim Doerr is the first place to ask about it.

I think you could make it look legal and pass a "simple" visual and sniffer test easy enough. Use some good modern cats made to clean not flow, put in an o2 sensor and don't leave the wires obviously disconnected, but don't bother connecting to anything real.

Today I received the 'classic car' license plate in the mail. Will go back and just get the safety sticker on Monday.

Thanks for the replies
