Check your alky pump for leaks. How old is it?

 

[dank GN]

I haven't seen any leaks the kit is about 7 months old

my o2's are low also and i think my alky was leaking so i havent even turned it back on...how does your alky leaking cause you to have low 02 readings if you dont mind me asking

Possible bad o2 sensor.

Possible bad ground at the head.

Could be..

the "bog warrener" sensor?? They may be an old design.. I've not seen them on the market for some years, now..

what o2's sensor do you guys recomend?

AC Delco or Denso, stay away from Bosch.

Have you verified your fuel psi is correct for the boost psi at WOT?

Fuel pump and hotwire?

Fuel pressure is good it rises 1 to 1

How old is the 02. When wa sthe last time you changed the fuel filter?

O2 is about 3 months old fuel filter is about 6 months old

AT WOT it "Dips" to 100?

yea but i have no knock what so ever. i am still curious about the post about alky every time i test my alky system my o2's jump up not down??? i am starting to think i have a bad ground somewhere . you would think i woud see major knock at that low of o2's reading?? is it possiable for the o2 to roller over 900 and hit 100 on scanmaster??

Higher 0'2sare richer and when you hit the purge you are richning the engine. 02's should go up.

make sure to double check your fittings on teh alky pump the meth will evaporate quick if it is leaking.

My recommendation is to remove the alky from teh equation get a KR sensor and get the car running right in stock form then move from there
