hello,
a little info on my car, mi 182k yeah thats high but it's been running so well been a great commuter car for me. Starts easy runs smooth and easy.
So I take it in to smog it and it fails due to timing being off but emissions pass. I got the timing sorted out the car idle's noticeably faster now but is now spot on stock timing and it fails smog on the 15mph test, the 25mph test passes.
ok I was going to list the test sheet but it's in a grid format and I am not sure I can reproduce it readable.
from the Test sheet. section that failed.
15 mph
rpm 2009
No (ppm)
Max: 731 Ave:216 MEAS:0877 failed

25 mph
rpm 2010
No (ppm)
Max: 798 Ave:187 MEAS:762 Pass

everything elce on my smog sheet passes.

I would appreciate any suggestions on things I should replace.
I am visually impaired and I find it quite difficult to read small displays , does anyone know of a meter that has a HUGE read out on it ?

Thank you vary much for your input.

 

Take a picture of the sheet, and post it. Inspect your exhaust manifold for any damage, especially near the primary O2 sensor.

 

Please give more details about the timing issue and how it was fixed.

 

Hi, folks at the smog place said my timing was at 13 degrees so the smog test failed due to that. Stock timing for my car is 16 degrees. My brother has a timing light and good eye's to see and with me slowly adjusting the position of the distributor and him on the timing light the timing was set to 16 degrees. btw we used a paperclip on the little thingie under the passenger side dash.
last day or so it's been raining and I don't have a garage so I haven't been out to try to have a good look at the exhaust manifold. I do have a camara with a macro lens so I will try to get a picture of my smog sheet posted.

 

The engine also must be fully warmed up and idling to spec to adjust the ignition timing correctly.

And how old are the ignition system components?
