OK so I'm working my way through all the little niggly things on the vit and the one that really irks me is its habit of sitting on 1800rpm till its well and truly up to temp and also sitting on 1500 for a good 5 seconds when you pull up at lights then drop back to normal 800

is this normal? spose I should ask that one before I dive into it looking for answers, does it with accesories on or off (for the idle up garbage) and turning the A/C on doesnt seem to be any different

I havent been able to download the manual for it yet but have the basic diagrams for the EFI so am going to check out whether the idle control soleniod is a straight out open shut scenario or whether it really does have a variable duty cycle to control idel speed and whether it can be adjsued somewhat (doubt it)

so do I have a problem or is it just what they do? even if it is I'll find a way to change it

[antt]

mine does it too. there's apparently a few fixes for it. i cant remember them off the top of my head, but it involves a 'wax pellet' that suzuki used to draw more air into the motor when its cold, but it doesnt close up when it gets hot, hence reving high

i'm sure theres another thing to it as well, have a search on outers or zukiworld, theres info on there about it. i never got around to doin the 'fix' yet cause mine isnt a DD anymore

i'll have a look around and see if i can find the info i had about it when i was gonna fix mine

[royce]

cool ta, I'll have a look around and dive into it

least I know it isnt just me

[antt]

yer, they're known for it

some links, with varying fixes for it. dunno what will work though....

[royce]

I found this one

http://www.zukiworld.com/forum/index.php?topic=929.0

I'll give it a try in a minute

[antt]

lol, i thought i had one on there, couldnt find the thing anywhere though

yer, mine was the sensor without wires, so contact cleaner didnt work ....i think that was about the time i gave up trying to diagnose mine

[royce]

well looks like its a tomorrow job now, dont have any contact clean left, be my luck we'll be out of stock at wrk too

[ANNODAM]

Royce, just for comparison re your idle question, I looked at mine when I started her up this morning & she idles on 1500rpm until warm then goes down to 900 - 1000rpm.

Mine does not rev high when I stop at traffic lights or have lights on, although does rev slightly higher when the air con is on 1100 - 1200rpm maybe.


Edited to answer your question below. Mine's a December 1991 model.

ANNODAM thanks for that, good to know there is a normal level to hunt for, what year is yours?

runs out to warehouse to get carb clean and contact clean
almost forgot all about it
I'm going to give it a blast tonight and have a bit of a look at some stuff like the vacuum valves and things to see if they might be sticking or something

[steve]

nah, this is just what happens to mechanics cars, they're always bombs. ... or maybe it was because you put big tyres on and bashed the guards in with a hammer

[royce]

you think thats its way of payback?

nah theres one thing I hate is engines that idle fast, the rest can fall apart I wont care but not the idle

appears we dont stock carby cleaner either anymore so I'll have to get some after work

[steve]

did it do all that when you first got it?

Yeah, the more your change things the bigger a bomb it becomes

[royce]

yeah it did but I put it down to a cold engine thing and didnt really drive it in traffic much

I'll fix it dont worry, and no more mods either, specially the custom home made idea ones

[Troll]

i have a similar problem with my sierra it idles normaly but when i switch my lights on it revs higher.

that one is normal (somewhat) and easy to fix

start the engine and warm it up, get somebody to turn the lights on and off while you look at the front of the carby, see the vacuum diaphram moving the linkage in and out and its adjusting screw? just wind it down till you get the speed with lights on you want

it will also do it with the heater fan on and if your a rich Japaneese guy with the flashy hardtop version the rear demister as well

otherwise you can unplug the slolenoid down near the temp gauge or the diode block hidden in the wiring loom to the drivers side of the dizzy

[Troll]

thanks royce

I'll have a play with that tonight
