Omega Owners Forum - Any ideas on this one?

Taxi Driver Omega Lord Offline OOF Holly Dog Posts: 8413 Swindon Gender: Drives: Fiat Scudo 90 Multijet (whatever that means!)	Any ideas on this one? 17. May 2008 at 21:52 Been doing it for a week now........ Doesnt do it all the time......but sometimes When I select P from either D or R, the engine nearly stalls......when it does it, it has always recovered and idles at 700rpm..... Seems odd to me as I would expect revs to maybe blip upwards slightly as load is taken of engine.... Any ideas?? Cheers

Nothing more than normal for a 4 pot Grin

I'll check codes tomorrow.....but its not been putting on EML for it....

Performance is the same as normal........

Maybe the throttle body needs a good cleaning out again......not been done for a while Undecided

Think ive found it!

Just changed the air filter and noticed a vac pipe under the airbox going nowhere.....

The pipe that didnt go anywhere one end, went to the evapourator for the lpg......the T piece it should have been connected to....one pipe went the throttle body........so not sure what that would have been causing the throttle to do.......but i think no vac on the evapourator means max pressure lpg being allowed.......

Not sure how long its been like it........poss since it went under surgery a few weeks ago Undecided

Tried it with engine running.....pulling of the vac pipe just seems to make the engine idle very slightly higher.....so something I wouldnt have noticed.......

But hopefully its cured the prob Thumbs Up!
