ok i took my car out for a cruise today. no big deal. but i noticed that when im parked and clutch in, when i move the shifter into a gear the rpms jump for a second. i was moving it from gear to gear and the idle was jumping. what could be wrong here???

Same here
Except when A/C is on even though the RPMs drop it doesnt do it.
It stutters like a stutterdrag box and only when no A/C and engaged in gear with clutch in.
Some one through in if its electrical. ( Transmission sending unit ?)

if your rpms are floating during slow shifts you need to check your Throttle position sensor and make sure its connected and calibrated correctly.

How do I calibrate the TPS?
Also I guess this is a little different from the starting thread since his idle BOUNCED..mine stutters when in gear only.

I've never done it but you look at the pfc and use a voltmeter.

I believe that's normal. My 7 was a auto then swapped to manual. And the mechanic advised that the 1st and 2nd switched didn't need to be hooked up,but the wiring diagram showed a sometype of voltage diff. i don't remember what it was.It was a while ago, but anyways i believe the 1st and 2nd switch causes that. I put it in nuetral it's idling 900 rpms,then put it in 1st ,idle might go up a tad, vacuum drops from 16 to 18. If that's what you are talking about, i think it's norm.
