I did a search for emissions it brought back 8 pages and after looking through the first 4 and not seeing the answer, I just figured it would be quicker to ask.
Sorry-
So, I took the emissions test this morning on the new to me- 1972 FJ40 and it passed everything except for the Hydrocarbons at idle.
Loaded reading: 94 - (400 is acceptable)
Idle reading: 974 - (again, 400 is acceptable)
1- Why would it vary SO much between loaded and idling? 94 to 974
2- Is there a quick fix like pouring some of the cleaner into the carb to get it to pass real quick?
Thanks for the input
