    99 GTP
    181k ish on engine.
    201k? On trans.
    Car stutters while idling in park, and while idling and holding the break in drive it sometimes tries to stall but so far hasn't.
    No vacuum leaks, even seafoam tested the lines.
    Does fine while driving, it's only when not moving.

    Plugs are great, wires are new, no misfires, plugs and everything, including this engine all have about 7 or 7.5k miles, including all the gaskets

    Yeah, I noticed that the ltft's at idle are like +11 up to +14 almost, and then when I put it in drive it went up to +15.8 ish and then dropped down to +3 and then back up to +14 ish again. But as always, once moving it almost instantly drops down to +/- 3 ish around 3mph and then down to -22 when cruising over 60 ish
