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.

Fuel pump, or maybe crank angle sensor

That is definitely the problem with my commodore VS, it has a short pipe with a 90degree bend on it but it just stops and goes no where. When I put my finger over the pipe, the car runs fine. When I take it off it stalls. Can you explain where the pipe is meant to go?

It goes to the purge valve solenoid down behind the drivers side head. Should be a long black pipe.
