****en smog is Tttttttting me off. Retested for a third time today and failed, but in a good way, if there is such a thing. Got two cans of Seafoam, one in da brake booster and other in the gastank and filled half with Chevron Supreem gas. Ran that half tank to "E" 4 empty, and then drop a gallon of DENATURED alcohol in the tank. Allow me post up all three results and take it from there.

IM DESPERATE HERE, TECH DUDE DID NOT KNOW I HAD DENATURED ALCOHOL IN MY TANK AND THINKS IN RICH ON GAS. THINKING ABOUT RETARDING MY TIME TO 14 DEGREE.
IM OPEN FOR IDEAS HERE.

 

Anyone?

 

Trip the tcu to limp mode and got a 43. o2 sensor, went to auto parts this morning and and got a new one, went with denso. car is in my drive way at the moment and will smog it for a 4th time today. I will post up.

 

S.O.B! Failed. Nox when up
max ave meas

HC (PPM) whent back down to an acceptable number

max av meas

I found my suction pump, and suck the egr, and the car shut off. So I assuming my egr is hold suction.
My last option here is to retard my timing, its at 16 dtc, and need to go back abit to 15 or possibly 14. Do you think this will get my NOX down, its only 18 points? Going back for fith test on Monday morning.
Help Help!

 

I cant afford a new cat at the moment! Ive swap out wire, roter, dizzy, plugs, oil, filter, oil flush. Im thinking of going to another smog station. What do you think?

 

which cat are you using? the accord cat? if so, it is smaller than a prelude h22 cat.
i have a 92 cb7 h22a bar'd. failed 1st time. i ended up buying a brand new magnaflow CA cat (not 49 state)
put that in, along w/ a new oem h22 o2 sensor and passed..barely passed, but still passsed

 

Does Mississippi have smog? I bet the cat on the car is the OG cat from honda motors. Where in the hell can I get a cheap online cat, free shipping of course?
Anyone?

 

Not sure what MS has to do with anything? CA has new laws-year or two ago- about cat's-feel bad for you folks. In NC a car "that old" only gets a "safety Inspection"-meaning if the lights work, tires have tread, no visable holes in the exhaust, good to go. pay your $13 and have a good day.

Anyway, I do have to ask, when was the last time the egr ports were cleaned?

 

Cleaned out my egr valve & ports recently.

 

It passed, blew an 7 on the NOX. Got a universal cat for abou $150. ****en paid overall $300.00. California emissions sucks ***! Some one should do a write on DIY smog emissions.
