idleing and suspension bush questions

blackers10 · 20-06-2006, 04:20 AM

hello guys
yes another idle thread

i have a 6 cyl au series 1 fairlane
and on idle it fluctuates about the width of a line up and down at around the 800rpm ish mark
is this normal for the I6 series 1s?

also if i give her a rev it revs fast then makes a fluttering type noise as it comes back down is this normal and also takes a while to rev down

also if i give it a slight push the revs go upto 1100 then wait there for a minute then comes back down to 800rpm ish is this normal?

next bunch of Qs are regarding bushes

i was inspecting my rear end (of my car you sicko

: ) and the upper and lower control arm bushes are very cracked and not so healthy looking

What sort of dollar figure am i looking at to get these replaced?
Should i go nolathane or rubber?
can i do it my self and are any special tools needed?
the ellery manual says it needs pressing out

thanks guys you have been a HUGE help!!

All your idle questions are the same as mine. I always thought it strange how it takes so long to drop back after a rev. As for the bushes l know that the fronts are easy to change as l done mine about 6 months ago but when looking at the rear irs set up it looked to be a proffessionals job as they do look like a press out job. I believe you can buy full kits but they are around 4-500 dollars a set. I would go just std rubber as the nolathane i put in the front are noisy as and will be changing them back to rubber on my next brake pad change. Its very embarrising when your new car sounds like an old valiant coming down the road.

On a side note l got some king super lows for your rear for 25 bucks if you want em???

Its preety normal on the standard I6's to have a slightly fluctuating idle, the ISC BPA is continually overcompensating resulting in the fluctuation of about +/- 70rpm.

cheers for the quick and useful replys guys

ill definatly take em providing postage isnt rediculous
how much is postage to morayfield 4506 AU-MUSTD?

did you go upto LOWS due to putting LPG in?

Yeah when l put the lpg on it dropped to start looking like it was sagging at the rear which most seem to like but l prefer it to sit nice and level. Lifted dit by about 30 mm and it's back level again. I'll check out postage but it might cost a bit. I thought you might be from vic but i'll let you know.
