ok that voltage should be higher when the car is runnin than when its off. so either the maf is bad or the wiring for the maf is bad.

i am currently switching cams at 5000 for my N1's in a 20ve. the reason i am doing 5000 is that from 4500-5200 rpms my afr lean out bad unless i add alot of fuel there but as soon as the cams switch it goes crazy rich. seems no matter where i move the cam switch point to it goes rich right after act...

people here who have sr20ve or any ve when you have your cams switch on does your afr get really rich at the switch point?

temp sensor is in spec with fsm data. the mechanical cold idle on the car works flawless. it seems to be more of a time thing in the nissan code. some sort of temp or time trigger for the o2 sensor. the reason i say that is due to the fact that no matter the temp of the engine the car will always st...

if you look at most non us model sr20 powerd cars they all run low timing up untill 2000 rpms in those maps and then ramp it up from there. i have changed mine in my 20ve to run from 20-30deg and it eliminated my car from pulling timing to 5deg on cold running and does not affect the warm running of...

the o2 seems to work fine when driving in the closed loop area. its the idle area that seems to be out of wack. the car idles fine for 5-10 sec then the o2 seems to when the car is warm run to a high voltage .85 or so and if the car is cold it runs into .01v or so. there must be some thing in the ec...

ok more information today. the car starts up with .32v on the o2 pritty much no matter the temp. after the initial start up the o2 volts will drop to.00 or .01v and thats when the car runs lean on the wideband now this will stay with no voltage untill you raise the rpms over 1400 then it goes into t...

o2 sensor is brand new. i have tried 2 o2s with and same issue. the o2 sensor ossilates like its supposed to when driving. the thing that is wierd is when you come to a stop when its warm the o2 will change over .50-under .50 and then it settles at .85 ish and thats when the afr goes into the 13's. ...

ok well here goes. i have a 91 SER with a sr20ve w/N1 cams that i cannot get to idle right when cold with the o2 sensor turned on. the car will idle when you turn it on for approx 15secs perfict after that the car jumps to 16-17 to 1 afr. now this happens only when the car is sub 80c. after the car ...
