i posted on a thread a few weeks ago about my car intermittently cutting out while driving and generally running horribly. it was running perfect last season and has run poorly all this year (lots of flat spots/hesitation/cf was all over the place). when it would malfunction the wideband would randomly go way rich to way lean a few times and it would load up, run on like 2 cylinders and stall. a couple times i got a code 42, but not every time. after a few wot restart attempts (to clear the flood) it would restart and run normally. i connected the laptop to it the other night to try to figure out what was up. with the engine warm i logged it idling and i looked at some of the tables. i noticed the target a/f table does not match the numbers i entered in the grid (not sure if they ever did when it was running good). also i noticed it was adding a bunch of fuel even though it was reading richer than target.
not sure if gnomes came in this winter and messed with my setup or i have a bad connection or defective component somewhere? the wideband sensor is a year old with about 3k miles on it, the map sensor is from 08 and came with the alky kit and i tried grounding it straight to the battery with no change. the last time i reflashed the pl was when the updated sd2 chip (the one with with dfco and spool mode enabled) was installed sometime last year, whatever version that was . anybody see any glaring issues? last year it was extremely consistent and ran really crisp and fast, i had it pretty dialed in and the cf was +/- 2 during most driving. i dont trust my car and havent driven it much this year, need to get it straightened out.
