The title says it all....well, most of it, anyways. Extremely low idle, warm or cold, in gear or not, it doesn't matter. When sitting at a stoplight, my idle is roughly 250 (last mark before 0 on my tach). Sometimes, it will dip slightly below that mark....that's when she starts to rattle/shake/try to stall.
On a side note....when coming off a freeway off-ramp, sometimes it will idle close to 1K for a while, then slowly drop back down. This is only after cruising for 10+ miles @ ~65 (2K RPM). Also...I *always* see a spike in RPM upon starting....usually up to ~ 1700 RPM. Sometimes, when the motor is hot (90+ F and running errands through town), she'll spike up to 2500 RPM or better, then drop back down to ~ 250
Relevant info....89 XJ with 4.0L, 216K miles, AW4 auto, new TPS
