Emissions (etest)

So seeing as your getting no codes I'm guessing you will have some sort of voltage at 2500 rmp with the jumper removed. On mine it was 2.2v.

 

Most of the tests you should find in the fuel injection section so if by MAF you mean air flow meter it is there.

 

Yes failure is a count of less than 8 and a voltage greater than 0

 

Yes down in Technical there is links to every page in the section

ST162 EFI System

 

Well theres a big shocker for you EH :wall:

You need to spend more time browsing :reading: our own

TECHNICAL FORUM :club:

where you will find pretty much all electrical aspects of the BGB have been covered.

 

86-87 1 wire, 88-89 4 wire!

 

if the oil is leaking out of the crank case bolt then find a rubber ring, put it on the bolt and it should hold the leak. i did something similar and it has worked perfect with mine, it stopped a pretty steady leak and has lasted well.

 

I have a small program (little over 2 megs downloaded and unzipped) I purchased online that is a complete trouble-shooting/educational guide to emission controls. It explains all the components, various readings, and helps guide you to finding/correcting the problem w/ tons of charts and graphs. It's been a great help to me, and for $20 pays for itself the first time you don't buy an expensive part you don't need. I found it at www.carleysoftware.com. Also, you can email specific questions to the guy who runs the site and he gets back to you right away. I sent him about 3-4 smog checks worth of readings and he helped trouble-shoot my problem(s) based on the various readings and how they moved up and down. The relationships between HC, NOx, CO2, O2, and CO can be complicated as hell. I highly recommend at least checking out the site and the example charts. Probably saved me several hundred bucks (at least) worth of parts and SMOG shop repairs.

 

hope u pass without too much more work to it!

 

Wish I could copy and print the CAT article from the emission guide (it's somehow locked into the program). Based on what I'm reading, I'm not sure a 2nd cat is going to help. The functionality of the CAT is based on A/F mixture, and amount of other gases present. When the ratios get out of whack, the CAT can't burn them and/or convert them to H2O and CO2. Additionally, the heat from the engine is a crucial factor and the CAT uses a lot of that heat to function. I think the ability of a 2nd CAT to further reduce emissions may be completely negated by the first CAT.

Disclaimer: I'm not an emission expert - not even close - so could be completely talking out my ass here; however, based on what I'm reading, I don't think I'm too far off. Just my ignorant .02

 

etests are such a pain man I totally understand...

I'm not going to get a real one when I try in springtime that's for sure....no way I'll pass lol

 

I posted about how I passed. I initially failed 2 times, then I retarded the timing all the way and pulled a vac line to run a bit leaner. sounded and ran like shit but put out sunshine and rainbows out the exhaust, allowing me to pass, then I just set everything back the way it was, and was back to polluting the air agian.

I failed by 2-3 times the allowable amount too... :roll:
