Car won't rev and stalls when cold.
Hi everyone, my ED Falcon has started having a few problems starting up in the morning. I usually give it a minute to warm up before I drive off, but I've never had problems when I have had to drive off quickly.
In the past few days, it won't rev past 1,000 RPM while cold. If I try, it will stall. After a hard time getting it to start back up, it will do the same. If I leave it for about 5 minutes to warm up, then it will let me rev to 1,500 RPM, but dies if I try to go any further.
If I let it warm up for about 10 minutes, I find I can rev it as high as I need without problems, so I know it's safe to drive off. Before I figured out this "test", it kept stalling every time I tried to drive off.
It's a dual fuel car, and does this on both Petrol or LPG, however I found that it seems to take longer to warm up when running on LPG. The car was serviced less than two months ago, and all the fluid levels are fine. Once it's running, it will run well.
The only other thing I have noticed is that it the idle when cold seems to drop to about 400RPM then jump back up to about 650RPM, this was never a problem before, and does not happen once it's warmed up.
Any ideas what the problem could be, or where I should start looking?
