LPE 475: Should I Eliminate Secondary Stuff If Changing Injectors????? - Page 2 - ZR-1 Net Registry Forums

Actually, I currently live in a county that does require emmissions, but, only if you drive a car more than 5,000 miles in a year. But, I will be transfering my residencey to Ohio on Jan 1. They have no emississions tests.

I will do wires while I'm there.

Coil Packs

....Is there a good test?
....Good quality Replacements?
....Aroundabout Cost?

Thanks all to have responded. No one around here knows anything about these!!!!!

The 1990 injectors will not tolerate the ethanol in fuel these days, that being said, do not buy GM injectors. Popular choice seems to be Fuel Injector Connection. Popular seems to be the SS, new. As opposed to rebuilt.
I have not done mine yet, maybe this winter. F.I.C. is where I'll shop.

Secondaries.
Some members have had some major engine issuses when the secondaries fall apart and you injest parts. This don't sound good to me.
Rumor has it, if you remove them, you'll loose a couple mpg.

Properly tuned in closed loop, (read: oxygen sensors engaged), mpg could actually improve.

That said, benefits far outweigh keepin' 'em, IMO!

Just wondering has anyone removed the secondaries and passed California emission test??

sammy · 11-03-2012

yes . i did the labor for a guy in porterville . we removed the secondaries and used marks reprogrammed prom and it passed . he sold the car since then and told the buyer passed also.

I empty the ash tray when it gets full of paper etc.
I could just toss it but what he heck.
Things that break on the car I just fix.
When it comes to the secondaries it's the same.
I fixed them in 99 and they worked fine until this year.
I rebuilt the air pump and I'm good to go for another decade.

One big reason I leave the secondaries in is to be able to remove
the power key any time i let someone drive it.
And it's a good conversation point.

Other systems that get pull that I choose not to are:
1. tire sensors
2. air bag
3. Cats
4. Bose system
5. FX system
