hey guys.. post uno.. i just picked up an '82 sedan.. it's pretty cool.. everything is blue, even the jack..

problem is, i need to pass an im240 emissions test..

HC readings 7.6/6.99 GPM Limit:4.0
CO readings 187.9/181.6 GPM Limit:45.0
CO2 196.2 - no limit
NOx .10 - no limit

this to me says i am rich and getting a shit burn.. i have yet to actually touch anything on the car.. i drove it home 20 or so miles with no plates.. it's kind of a turd..

thoughts?

Have you done any sort of a tune up on it? have you timed it? done a compression test? all things you may wanna do if the car is new to you.

is there a functioning cat on it??

i drove the car maybe 20 miles home when i bought it.. it didn't sound bad.. or smell bad.. but it also didn't have much power.. so maybe it's clogged..? i guess i don't know the checks for a "functioning" cat..

All these threads about emissions tests make me very happy that we have no such thing here in Alberta. Only have to safety our cars once when we first buy them too...

okay.. thus far i have changed oil/filter and plugs.. air and fuel filters look decent.. wires/cap/rotor look decent..

timing was below 7* btdc and i advanced it to 15*btdc.. all of this makes the car run a bunch better.. but it's still on the soft side..

after looking for my laser thermometer.. and not finding it.. i used an old meat therm.. not the best but it got me in the ball park..

front of cat was just above 250* and the back of the cat was a bit below 150*.. tells me it's not workin..

in the end i want the car to have a v-band cat section so i can drop it in and out as needed.. car will have some sort of 4age in it.. but that will be in the 2.25 or 2.5 inch size.. so it will be a mess fitting it in now..

ideas around this mess so i can get it plated and start getting all the junk off...? our e-tests are valid for 2 years..

the car is still running rich.. i need info on adjusting the stock carb.. i think i need to clean the check balls in the charco can.. as this could allow fuel in.. are there any other fuel enrichment items i should check..?

Do you have a picture of the sticker under the hood with the vacuum lines? I would replace all the lines and rebuild the carb. fresh seals would help a lot with idle issues. Is this test done on a dyno? I need to know what emission stuff is on your car cause each year and model/ sale location changes stuff. there is over 14 system on stock cars to check and rule out. If I had a scanner I would post up some stuff from the service manual. The first thing to check is if the distributor is holding vacuum on both ports. If not you might need to replace them.

i'm not even about to go thru downsizing all of these just for this forum..

there are pics of a couple things.. the tags under the hood.. the goo under the throttle pulley and checking if i'm right on the idle adjustment screw..

side note: kingsland eah? navy or native? my wife has family in the camden county..

Yea I'm not native to Kingsland and not in the navy. I have just moved to Saint Marys behind the navy base. I Think right behind a gun range. I think the air induction system is not working right on your car. The pump could be bad, any of the the many vacuum lines could be leaking. I would replace all of the vacuum lines one at a time. That way you know for sure they are not leaking. Most of those lines are 30 years old. the 02 sensor could be bad or the emission computer is dead. I think you can test the air pump with the car running and see if it blows air out of the tube. There is 8 pages on how to test the whole system. there is 4 vacuum switches that send out voltages to the computer and open other vacuum switches. I would make sure the distributor holds vacuum also. I will try to take some pics of all 8 pages.

i'm gonna take on replacing all of the vacuum lines.. the thing that confuses me is it's running rich.. which leads me to believe some sort of fuel enrichment is happening that shouldn't.. could a vacuum leak to something be the cause? guess i'll find out..

when you say to check the distro for holding vacuum.. do you just mean the two nipples on the advance on the front..? pull vacuum hose off, put hand vacuum pump on, draw vacuum and it should hold?

Yes hook up a vacuum pump to the nipples on the advance. Also I don't think you are running rich, just not a complete burn. The air pump system helps the fuel keep burning in the exhaust manifold, thus allowing lower co ans co2 levels. The diagram all dark tinted line may have fuel vapor in them. After the line replacement I would check to see if the air pump is putting out air. Just make sure to replace the vacuum lines one at a time. I will try to get more pics of the book up later to night the tropical storm knocked out my power at the house.

okay.. after the stuff i mentioned above.. the car seemed to be cleared up.. was on the highway for like 15min headed home.. thought i'd swing into the emissions place.. it was good and hot.. maybe it will pass..

nope..

still way high.. on CO..

i checked the air pump.. pulled hose off top of pump and it was sucking in.. pulled hose off back of air cleaner and it was pumping out there.. seems to check to me.. i then got my vacuum pump out.. it was acting funny.. but i was able to make it hold a steady number while messing with it.. go to car, neither port on the distro would pull any vacuum.. recheck pump is working, it does.. so i'm thinking that is an issue..

at this point.. the car is a at half tank.. it's been advised to me to fill 'er up with E85 and retest.. heard some amazing stories.. think i'm gonna try it..

ha.. E85 at about 50/50 in the tank and it passed with FLYING colors.. so now on to a weber/holley..

Cool that the e85 trick worked. If there is know vacuum at the dizzy then the timeing is not advance timing is not working. It its leaking air to the carb making it run lean. It will have more power at higher rpms. You can plug the lines and it will help some. Does anybody know a way to make a pdf so I can share some of the service manuals?
