How do you fix Code 21? Car is 95 S14.

Is there a creditable auto shop in fresno/clovis area? I have to get it smog this year.
Thanks

you... clear the ecu code right before you smog Wink
i did that today.
I failed smog 3 times in 2 weeks. today i swapped my cat, O2, put in stock cams, adn did a good tuneup

My car is currently throwing 3 codes. TPS signal, Tranny some kinda somethin, and something else lol
ANYWHO... i just pulled up, reset my ecu and BOOM... passed smog =)

I went to a place on belmont. they charge $25 if you fail and the next time you go to smog, if you pass its $30 !

I'd recommend them because they're cool as shit and into cars =)
I'll get back to you with an address/number

I reset my ecu but after 5 miles it comes back on. What's the name of the smog station?

CEL code 21 problem solved on my 95 240sx. It was a bad distributor after taking to 3 autoshop.

Distributor is expensive, so I bought a used one to test it out. my brother in law helped me remove the old distributor and installed the used one. Took several times before it crank up. Adjusted timing and passed smog 2 weeks ago. I went to smog shop below. Free retest if you don't pass smog.
