well mother f*(k :: emissions
 

f**king went to get smogged a while ago, after hundreds of dollars in parts and countless hours of f**king work.. and mother f**king god damn son of a bitch failed AGAIN
HC: 905 - 220
CO: 6.33 - 1.20
(with new exhaust new cat, full lean idle, f**king god damn even had the air pump hooked to the cat via the split air pipe, can of that GTP 'pass or we pay' bull sh*t)

what the god damn f**k is this bull sh*t... now what do i have to do to get this mother f**king to god damn pass this stupid bullsh*t fucking god damn what the blue f**k is the problem... leaky injectors? god damn mother f**king hell this sh*t is so f**king stupid

now: violently ripping out all emissions bullsh*t

there, edited the body myself.

title edited for profanity... please avoid using profanity in titles and bodies of threads.

sorry... very unstable at the moment..

make that THOUSANDS of dollars in parts, and hundreds of hours of work

From the time you last posted to now. Did you run the car alot??? I mean was it good and hot b4 you went to the smog?? that's is one common thing that I read when people talk about getting smog. Just asking

yeah, it's about a 30 minute drive to the testing station :(

have the basics been done first??? new spark plugs/and cables, new air filter, new O2 sensor, new fuel filter, clean unleaded regular gas...

Those things should all be done first. Then check things like EGR (if it is a S4).

yeah i did all of the basic things, new plugs/wires, cleaned my air filter (k&n) replaced o2 sensor when i replaced the exhaust, fuel filter is fairly new, very fresh gas from last night, did most of the stuff on jrats emissions cheat system, all but the alcohol, and still failed horribly

i didnt check the EGR tho, but wouldnt think it would make that big of a difference... my only guess is that the injectors are leaking... it consumes fuel like crazy, runs rich as hell, and HC's are caused by unburned fuel arent they?

why didnt u do the alcohol trick?? my brother did with his mr2 n they were amazed at how he got such a low count

mainly because im flat broke... wouldnt have the money to buy the alcohol, or the gas after i tested... im just screwed i guess.. my daily driver's oil pump went out when i bought a parts car to fix my 7 with.. so now im stuck without a car at all.. no car + no money + no job = screwed.

What have you got on your parts car to sell???

i was gonna trade the rest of the car for a paint job.. but doesnt look like that is going to happen after i failed so bad.. i might as well build the parts car back up and drive it (87 TII parts car)

What alcohol and where do you buy it?

can you cheat? just route the air pump's outlet hose directly to your cat, bypassing the ACV.

that works on 1st gens, not sure if it'll fly on a 2nd gen.

instead of decreasing the parts, increase the millions! :)

^That's a good one

He already tried that, if you can desipher his original post.

a buddy of mine's corolla passed with straight pipes after he used aviation fuel and alchohol. he said it burned so clean, the exhasut tip rurned white.

that is exactly what i did... and still 700 over the limit... time to turn this POS into a track car, or a paper weight

my last resort is buying 4 new injectors, or getting mine cleaned up and rebuilt...
does anyone think leaky injectors could cause the HC's to be that high? 700 over the limit?
HC's are caused by unburned fuel so.. this could be the problem? any input?

anyone know of a quick way to find out if the injectors are leaking? (without pulling them) like.. i could leave my fuel pump on, and see if it floods or something? would this help narrow it down?

What you need is to find a place that will slap the sticker on for 100 bucks...i know 2 people that do that here in RI .... too bad u dont live in RI i could get u the hookup

yeah, i thought about asking the dude if he would take some $$ to pass me. but he was old and nearly deaf ... probably wouldnt have been too good if i had to yell 'HEY IF I SLIP YOU 50 BUCKS WILL YOU PASS ME'

Have you checked your coolant temp sensor (the one on the water pump housing)?

no, i havent checked that... could you tell me how i could check it.. on a poor mans tool budget..

Only real way woudl be to pull them and then zip tie them to the fuel rails and fire the engine. You can then watch the spray pattern of them to see of any leak or have a bad spray.

im just wondering if leaky injectors could cause the HC's to be high like this... also i put 14$ in gas in the car last night (roughly half a tank) now it's dropped to a little under a 1/4 .. and i drove a total of maybe 40 miles today IF THAT... so im thinking it's something to do with the fuel, but knowing me, i pick the top 10 hardest things to trouble shoot before i even think of the simplest things.. im trying to avoid a tear down at this point.. ive spent 3 solid weeks working on the car.. had no sleep.. so im wanting to get it just narrowed down at this point

You know if your O2 sensor wire is not sending signal to the computer, it defaults to full rich mode? That can mess with all sorts of things. Fuel economy and emissions most of all.

i put in a new o2 sensor.. but i thought that only effected cruising fuel econ, not the type you would have at idle getting smog tested

Can you explain how the coolant temp. sensor would effect emissions? (I too just failed the test).

How can you test this?

ECU runs the car richer when cold. If CTS is not working and registering -40 degrees, the car will run rich all the time.

how would you go about checking the cts to see if it's working? *broke* how much do they cost to replace?

well im bout to go to sleep, gonna trouble shoot it all tomorrow when i get up, if anyone can give me any last minute suggestions, and tell me a quick easy way to check the CTS i would be very gratefull

thanks,
alan

I get mostly 12 mpg 9 on a bad day, but before it ran like crap i passed emissions, I replaced the cts myself and it didnt help one bit, it was like 18 20 bucks i think..check the air temp sensor, thats one thing i didnt get too yet and it could be a problem, I need to get a ohm meter and check all that stuff, the ats is on the drivers side of the Upper intake manifold, also sounds silly, But make sure your intake pipes are all tight and the clamps are on good, Ill let you guys know when i find out whats wrong with mine if you do the same with me, I am having a hell of a time trying to get back up too 17-18 mpg like it used to be, But i think my cat is a factor, get back to you later

Yeah, when the sensor fails or gives a reading that is outside of a preset perameter, the ECU substitutes in preprogram value. For the coolant sensor, that is -40 which is the lowest temp it can register, and a value that will cause the ECU to schedule the most fuel. ECU does the same thing if the O2 sensor or air intake temp sensor value is lost or incorrect.

well, to teast the cts, first see if there is voltage from the reference wire in the first place. Look in the FSM for spec numbers, but i'm pretty usre our cars use a 5V ref. Anyhoo, after that, test the signal voltage from when the car is started until it warmes up. It should start at a low voltage and slowly go up as the coolant heats up.

Just think of it from the cars perspective. I know it sounds dumb, but it helps me when i'm trying to diagnose things. I'm dumping a lot of fuel into my chambers. Why? Cause i think it's cold.... or I think the air coming in is real cold/ i'm always taking in a lot of air. Or my oxygen sensor keeps telling me im lean, so i keep dumping in more fuel. Think of all the components related to the fuel delivery, and check them.

hey man save about 300 too 500 bucks pay some guy under the table , thats what i do!! good luck

sounds good, thanks for the help everybody... i got a nice list of all the things i need to check out tomorrow, i'll let everyone know what i find, be a good future reference for anyone having trouble passing emissions, because i am going to check EVERYTHING that could effect it, taking common sense, old threads, this thread, fsm's, etc and doing a full check up.. maybe i can beat this problem once and for all.

thanks for all the help,
alan

you know what i just decided... im gonna break out my FSM, my Digi cam, and spend the next few days doing an Emissions/Fuel Econ write-up... checking everything i can check, replacing things i can replace... well, unless it rains *shakes fist towards the sky*

I ran into same problem with the smog test. After 4 tries, I watched the tech hook up the car and program the smog computer. He was selecting the 4 banger and not the rotary engine 1.3l. It passed when he entered the correct engine code "r" at the bottom of the list.

The factory service manual has a procedure. Manual can be found in the FAQ.

well, i just replaced the sensor on the water pump housing... i looked at it and said to myself 'how the hell did Aaron know' it was broken almost completely off, hanging on by some brittle plastic... replaced it with a spare i had in a parts car, im just hoping it's gonna make a difference emissions wise
