o2's read slow sometimes others they are fine
My o2's don't seem to be functioning correctly sometimes they are very peaky, other times they stay rich then go lean and stay there for a period of time. I also have tried the tunning MAF less and can't seem to get it on point for 0 to -4 LTFT they want to bouce back and forth between -6or -8 to 4. Could this have something to do with my o2's reading slow? If somone can tell me how to post a pick of my hptuners graph I would be glad to show what I am talking about.
Thanks,
..RJ..

I just replaced the o2's about 400 miles ago when I first put the motor in and I am running 01' injectors I am also having a problem with the idle but only accasionally. Sometimes I start up the truck and it idles fine then after pulling off and pulling up to a light or even if i depress the clutch for a period of time the truck wil just idle to zero like the switch has been cut off. If you start it back up it continues to do this until you turn the switch off for about 30-60 sec and then you can start it and the engine idles like it should. I haven't had any other idle issues and it recovers fine. I thought that it sould be an IAC issue but I am unsure?

I am not sure? I was completely lost when changing over to newer injectors so I asked and the reply i got was to copy all of the tables from a 01 and put them in my 00 tune. so that is what I did. I did notice that the 01 injectors worked off of a soak style setup where the 2000 model doesn't have that option. None the less this is what I did whether it be right or wrong. what exactly is the ifr table and how do I know if mine is correct or not.
