||Can look at my modslist under profile., Basically i have gone Haltech.
I like a higher idle 900-1000 rpm. Has been fine for a while. Initially when started, had the higher idle until warmed, maybe 1500, then would gradually drop, normal.
Recently start-up is odd, I get idle that fluctuates 1000 to 2000, pulse, like every second, just up and down. Not a TPS issue, placed a new one. She drives fine, but at idle does the up and down thing. Once driven and warm (warm meaning, temp gauge says operating temp, but still up and down). Once get to gas station for my E85, just a ten minute drive, she idles fine. Rest of day, after hours of setting starts up and idles fine.... A/F on bith sides 14.5 to 14.7.
Tried some research, thought O2 sensors?, but work fine after this weird start up. Read coolant temp sensor can cause some issues....have not checked that.
Just wonder if anybody ever heard of this, any suggestions?
For reasons, I am replacing the exhaust from DP's back, so, if anything I can check, now time to do.
Appreciate any insight.....?
