HC PPM is too high at idle and at cruise RPM. The motor has a slight misfire. I tuned it when I got it with new ND plugs, Toyota cap & Rotor, Set timing to factory spec.

I have not done anything else yet, but am planning on doing the valve lash, and thinking about swapping the stock coil for a Jacob's one I used to run on my 70 Pontiac Ram Air III 400. Is there anything special about the 85 Toy EFI coil that would stop me from doing the swap? Oh ya, the wires are still stock too, thinking about replacing them as well.

Need opinions on what approach to take, Good news is I have till 7/31 to dial it in.

Thanks in advance!

I am not really sure what the issue is. My 85 22RE passed without trouble in San Jose this year. The one piece of advice I might give you is to drop the cat and take a look inside. For $100 at Napa you can get a new one if it looks like the honeycomb is damaged or missing. A new cat can really clean things up even if it is not totaled.

Re-sent it with some q's

yup a brand new cat will clean up everything! Just make sure to get your motor really really hot and it will pass.

a new cat will hide a lot of problems.. but a efi rig will pass smog without a cat when everything is right... As far as what comes out the pipe

You need a cat. Or if you still have a miss that you can not fix run a second cat to burn the rest of the fuel. Also change the oil because gas in the oil will dirty up smog check. Also DO NOT USE anything but 87 octane because it burns more completely than higher octanes, Also lowering HC. But it is possible that this isn't enough because you didn't post how high the HC PPM was.

before you go adding 2 or 3 cats get the missfire problem solved.. Hydrocarbon is the product of a missfire.. Like I said before a cat can hide a problem but why not just fix the problem...

Steve,

Have you checked the plug wires? Slight misfire kinda points to that, and the subsequent high HC at both idle and cruise.

Ohm them out and see what you get. Spec. is 25k ohms.

Pat's right, a 22R-E will pass with a gutted or missing CAT if everything else is tuned and set to spec :D

Ummm...if I remember correctly HC has to do with the EGR valve--yours may not be working or may not be getting a vacum signal to actuate it. I failed a pre-test a few years ago due to a non-funtioning EGR. A new BVSV cured the problem.

Keep 'em coming! Making a check list.

Thanks everyone! :D

Got a metal coat hanger? Good, cuz youre going to use it!

Pop the hood. Find your egr valve.
Now find the cast iron part that goes from the head to the back of the upper intake.
On the lower part of this, almost half hidden is a metal port with 1 screw holding it on, and a vacuum hose attached to it.
Pull off the vacuum hose, and straighten part of the coat hanger.
Shove the hanger down in the hole, hard, and repeatedly. Eventually you will break through into the main section. Keep feeding it back and forth to clear the junk out of the small port.
This is the first place the egr plugs up.
Also, your cat could have gone bad, maybe. And check you O2, make sure its working. More than likely your egr is doing nothing, causing your high HC.

I would do a valve adjustment.

When I had high HCs, might valves weren't adjusted right. They were too tight, causing the valves not to properly close. Which cause some leakage of fuel during the compression stroke.

I guess the valve stems must stretch due to the spring tension.

You didn't state how bad it failed.... are we talking 5 hydrocarbons over or 500. That is going to make the determination on the issue. Defenatly get the miss taken care of. If you are still having issues back the timing down a little. They usually allow a pretty big range of fluctuation.


I took my GF car in for smog and it was real close (157HC PPM allowed it was at 155) but the car failed for another reason. I fixed the other problem but I just wanted to make sure it was going to pass. I pulled over a block before the smog shop, cranked the timing back and took it in. It passed with flying colors (27PPM). The guy did say that the timing could be advanced a little and it would run better..;) .

Just a thought....good luck..smog laws suck.

They guy just did a quick sniff, and gave me a printout with the HC at 1576

I'll know more when I do all the stuff you guys are helping with.

Thanks agian! PBB is the :flipoff2:

WOAH!.....1576!.








UH....you really need to find that miss....:flipoff2:

That was what I was trying to get from him before. That is high forr ppm you should find which hole is dead. If you want back the plug wire off about 1/2'" from the plug on whichever hole is not firing and that will be a quick way to tell if it's a fouled plug or gaped to small. it will amplify the spark. Sould check EGR also the pipe goin to the manifold gets pluged up. Oh buy the way my truck passed with 13 ppm in HC:D

That miss sounds like a flakey plug wire to me....

Oh to address a question steveh asked LONG ago...

You can attach a Jacobs coil to a 22RE. I have an "ulta coil" on my 1989.

You will need to use the OEM ignighter. The EFI DOES use the ignighter to set the timing.

Simply tranfer the same wires over to the Jacobs coil.
I saw no performance enhancement, but it seems to do no harm so Im leaving it.

IMHO - Jacobs wires dont seem to last that long (i.e. I end up pulling the boots off em.)

I'll resevremy opinions on Jacobs stuff to off line.

(shameless plug - new Jacobs Energy Pak box for sale - never installed, brand new - for cheap)

Id suggest an OEM set or if ya have $$ - I think the Magenecore set is a fine item.

dead hole. 1576 is stupid high for HC. your junk is broke.
learn about smog check- 4 gas info (http://www.visi.com/~rhayman/smog_faq.html#Preconditioning)

if you can understand that you'll be able to fix it the Right Way.

No dead hole, it runs pretty well, just a slight missfire is detectable. Dead hole would be running on 3, it's running on 4. I wonder if the printout the guy gave me is mine ....... :confused:

The way all of you are reacting to the #'s makes me wonder.

Ok, read the page, his use of "Dead hole" is not how I would use it, but points to the ignition problem. Good referance, thanks!

Steve PM ToyFamily, Nicks dad had a hell of a time getting his to pass, it had a slight miss but he finally figured it out, there was a number of small things wrong with it.:smokin:

Will do, thanks!

Steve, run your tank down to about 1/8 tank, then put in a gallon of methonal, drive straight to get it smogged. After you pass fill up your tank with regular gas. Problem solved. :D:D

BTW: My brother did this and it made his truck pass with flying colors. No new cat needed. :D:D

Also, I do have a brand new cat if you want to borrow it.(I only use it for smog tests) :D

To funny! A special cat for smog! Thanks Tim. If me getting off my lazy ass and doing the basic steps, valves, wires, etc does not do it, expect a call. At least I have till 7/31 to iron it out. Call me if you want to make a quick local run, I may be able to sneak away Sun afternoon if I get enough work done around here.

Steve,
I had the same problem on my 87 turbo last month (in MA). I failed the HydroCarbons miserably- but the Carbon Monoxide was great. The only thing I did was change the cat- and both went wayyyy down. I have the before and after printouts- I'll see if I can scan them so you can see the before and after difference.
Allan

I had the same problem. I had to replace the TSP and set the timing. Make sure you jump the check light plug when you set the base time.

get a mail box in amador county:D
