not boosting???
not boosting???
hmmm on the way home from picking up the starion from the previous owner on Tuesday night, the car decided not to boost up.
The car was fine when i took it for a test drive 2 days before and halfway home it was fine, then it started making a nocking sound like i had run over something, that happend a few time after that, then it stopped coming on boost.
The car was running fine after that, it just wasnt coming on boost at all and the turbo wasnt spooling up.
Whats wrong??? has this happend to anyone else??? or is my turbo or somthing else farked???
Also I tested it as soon as I got home today just to make sure its not a one off thing and it sounds like its running fine its just not spooling up at all whenit reaches 2500 – 3000 rpms, I even went higher to see if it would still come on like 4000 – 5000 rpm and still nothing
i rang the previous owner as soon as i got home and told him what happended and he denied any knowlege of this happening to him (of couse)
anyway this has got me stumped to what it could be so anyhelp would be really appreciated, thankz

Hmmm
And the previous owner "knew nothing" about all that. :x
Sorry to hear what happened to you but I guess the real answer as to why he was selling it is now known.
Anyway, a broken Starion always comes back as a better Starion.

Never argue with an idiot, it brings you down to their level and they beat you with experience.
Where is the hole?
There is a plate on there somewhere (can't remember exactly, will look at the one I have at home tonight) It may have just rattled off or something simple. Unless of course it's a hole blown through the exhaust housing or something like that.
EDIT: Just read your other post.... bugger.

O2 Sensor?
Might explain why he had knocking sometimes when he first drove it also. Its also right next to the little turbo problem area. ECU could be just adjusting the fuel ratios from crazy o2 sensor values, causing a surge.
Only take a few minutes to test with a multimeter.
Just an idea.
I did think boost sensor, but my car drove alright without it, it worked for 10 minutes the entire time I owned the car.

Sounds suspiciously like the computer protection kicking in... Maybe its boosting a bit high, or your vacum advance/retard isnt working...madeofmilo wrote:Hey guys now I have golden boys starion...well it surges on boost pretty badly...everything is good.

checkl both.
jerking
my ja jerked on boost when i first got it mainly under a load like going up a hill. it turned out to be the vacuum advance unit on the distributor, take the hose of it and suck on it then block it with your tounge to see if it holds vacuum.

you probably don't want to hear about my falcon? filter i got from supercheap that 'should do the trick, its what all the drag racers ask for!' that i got for $18 then?
also you said your boost sensor was disconnected? what does this do besides shut off the fuel when boost is too high? does it adjust the injector pulse? or is it purely a fuel cutoff? if it is can you just disconnect it or do you need to change some of the wiring so she'll still run right?
cheers
