VT V6 Auto - Splutter/Stalling on start up bad fuel??

[jamiev90]

Hi Guys,

All of a sudden since i fueled up at my usual service station, my car has been acting abit weird.

The day after i fueled up, i went to start my car (after work and after driving 40km's) so the engine wasn't cold, it kinda of started/spluttered and shoke and then shut down, second time it did it but it held the constant shaking/spluttering and as soon as i tried to get it a little revs it shut down, third or fourth go it worked fine, and then did so for about 3 days,

this morning the same thing has started happening again, and then it runs fine..

any suggestions what it could be? could bad fuel be the cause?

Thanks,

Jamie

have a look at your iac (idle air control) meter on the throttle body clean with carb cleaner . be careful not to move the pintle.

I have been having a similar problem, just wondering if you have found a solution to this before i start pissing money away fixing s simple problem. i was possibly thinking injectors

Something that may or may not help. There is a pipe on the bottom of the throttle body, with a elbow connecting the pipe to the TB. It seems to be a Ecotec problem that this hose comes off quite often, and causing the car to run really rich. On my car it has come off twice, first time costing my a new cat, and it came of my parents car this morning. I think this hose is the fuel pressure vaucuum (?) hose or something. Worth a check. Also worth it for evryone with Ecotec to zip tie this damn hose.

still no fix yet, have just spluttered and died on starting up, as soon as i touch revs it just cuts off.
