Have a 1992 Ford Ranger 2WD, 2.3 L. EFI engine, pushing 200K miles on it. Having some trouble passing HC emissions test: CA smog.

 

Welcome Norm!
Looks like YOU win with the 2.3 with the most miles forum!

 

Welcome!

 

Welcome to RF. CA emissions blow. What are you failing on?

 

welcome

 

only the Hydrocarbon emissions. 121 measured and the limit is about 93 or so.

I am checking everything. NO stored codes, timing is right, Vacuum OK, computer tests performed so far are all OK. New plugs, wires, electronic spark module, Oxygen sensor, etc.
Oil and filter. Air filter looks clean. More testing tomorrow.

That sucks man. Any exhaust leaks, missing CATs? Emissions are no fun, and re-testing it and failing again just gets expensive. Wish you luck on that. Might search on here, see if anybody else has had similar issues and what their solution was. I'm sure that lots of people have had emissions issues on here.

 

The California red flag smog curse!!!!

im no smog pro, but i got a few tricks you can try, thats MFI aint it?

o yeah, and welcome!

 

Do have access to a scanner?
I had a similar problem with my mustang.
It turned out to be the gas tank line sensor
