revs up and down question

[mac456]

hi,

just wondering if this is normal, i noticed today when coming to a stop at trafic lights my revs bounced down then up just over 1k then idled at the correct place.

iv kept my eye on it and hasnt seemed to happen again (it just dropped when coming to a stop and then idled)

so is this normal or a sign of anything? like throttle body cleaning?

if it starts doing it again ...clean throttle body , mine did this and r-tech cleaned the throttle body ,remove pipe from throttle body have someone hold the throttle down , use a rag and spray some kind of cleaner on it and get cleaning ,this sorted mine

i noticed this on my car yesterday, rev's wont going over 1k on tick over but needle was moving up and down. however i doubt mine is down to the throttle body needing cleaning as it was done when i had me remap done 2 months ago.

was the car even warmed up at this point?
