My turn again.... CO% to the moon


Active Member
Smog hasn't been an issue for me for a few years but recently I've made some significant changes and now am at GP levels.
(42# injectors and DW300 pump)

I forgot to turn the FP down, and am hoping that is a big contributor to the #'s. It was also throwing a code 45
HC @ idle - 388 @2500 - 184
CO% @ idle - 5.51 @ 2500- 5.52

I've got Erics emission chip installed, and of course the cat. (only used for testing)

Is there anything else i should change ? I've never had to mess with the Translator settings in the past.


Go on red!
I accidentally may have zip tied the throttle blade when I was working on something else, testing the tps, so it only opens part way, enough to only go 70mph...

UPDATE, fuel pressure adjustment did the trick. Back to legal limits.

Cheers ya'll ;)
