Well after failing the first time because my fan wasn't working and it overheated....fixed but note the guy said it failed because something to do with my rpms..maybe intake, but they couldn't give me an answer on how to resolve it...what do y'all think it might be? http://img.tapatalk.com/d/12/12/15/y2yvyma9.jpg
Did you Seafoam it before going in for inspection?
Find a friendlier inspection station...
Was it hot before you had it inspected? Take it out, drive the snot out of it and then take it in.
Bump your timing back and go somewhere else...your going to have to pay again anyway.
Like Sammy said, put a bottle of http://ecx.images-amazon.com/images/...500_AA300_.jpgand flog the hell out of it, get it up to temp.
Back to factory Timing spec & RxP FTW!Quote:

-i seafoamed (put it in gas tank) when i got the car about 2 months ago...
-it wasn't really hot, i just went during my lunch time really quick and left it at the place
-hood was open when he did it
-bump timing (is that an easy process?)
i also have a jr intake, should i install that before i try again?
I'm with Trey, how with old is your catalytic converter.
Well doubt it was ever changed.. And if so its the oem 91 one
It's easy to take off and check out the guts on the inside, when mine went out it was obvious it was time for a new one. Passed every inspection since and that was in 01' or 02'.
Just bought rxp, should i put it in the morn and wait till the weekend to test it?

BTW - seafoam will do a lot more for you if you run a can through the intake via a vacum hose. Makes a giant smokey mess, but I have first-hand experience that it drastically improved the idle and response on the 91 I recently fixed-up.
How does someone charge less than what the state sets as the going rate?
1. is it ok if i use both products, rxp - gas and seafoam - intake manifold?Quote:

i really hope i can pass this soon, im like bobbing and weaving the po-po
Have you checked the timing yet?Quote:

Now part of my annual procedure for inspection is to adjust the timing before I do anything else. ;)
sucks to admit this, but i dont know how to do that

What causes High NOX Emissions
Thousands of technicians have faced the challenge of bringing a particularly stubborn application into compliance for NOx emissions. High NOx readings are a clear sign of performance issues somewhere in the system. The question is, where?
Among the potential causes of non-compliant NOx readings are:
Misfire condition
Malfunctioning or improperly adjusted EGR valve
Failed oxygen sensor
Leak in exhaust tubing upstream of converter
Excessive carbon deposits in combustion chamber
Improper spark advance
Blocked coolant passage
Overly lean air-fuel mixture
Damaged cold air duct
Failed or malfunctioning catalytic converter
Corroded or damaged engine sensor electrical connections
Please note that while a failed catalytic converter will contribute to high NOx readings, the failure in itself may have been caused by some other upstream performance problem. In all cases, it is crucial to identify the root cause of the problem before blaming the converter.
Get a timing light from Harbor Freight and follow this: http://www.miata.net/garage/ignition.htmlQuote:

Nope, use the blue "Aux power" plug in the pointy link.Quote:

Sorry for the dirty engine bay, but which vacuum hose do i use to introduce seafoam in my engine (91 1.6)
http://img.tapatalk.com/d/12/12/20/u9upa8a8.jpg
Just get the seafoam in the spray can with the long plastic tube. you won't need to use a vacuum hose. plastic tube just inserts in front of the throttle body and intake hose just slides over it.
Use the one just to the right of what you have circled. No hose, just the rubber nipple.
Lol...i ended up returning the one i had for the spray, right before you commented...thanks though

Did you buy the blue miata with the polished hood that was for sale awhile back?
well it was painted gold, not the best job btw but i think it is the same one your talking about
Holy crap....I've never seen so much white smoke
You did it right...Quote:

Haha heck yeah!
Didn't pass again....
Were the numbers any better??Quote:

I know your pain.
Sometimes it helps if you leave a 12 pack of beer in the passenger seat. Kind of like leaving cookies out for Santy Claws...
Just ordered a Catalic converter...and most prob will switch out spark plus this week...hopefully it will pass then
Just got this in the mail, about to head to auto zone abd get some new spark plugs and wires....hopefully i can take the test tomorrowhttp://img.tapatalk.com/d/13/01/05/unage8e4.jpg
With Nox that hight it means your running too hot.
