Hi! I recently started having a strange random start-up issue in which my car would start up really hard when it had sat for a while, and the problem seems to occur mainly when the fuel gets below 1/2 or so.

I had new spark plugs installed and the fuel filter checked, and it all checked out.

But now recently, once or twice I've had the problem that the car starts up just fine, but when I shift into Reverse (after an admittedly short warm up time), it starts to roll back and then the engine just quits. It's not violent and it doesn't buck, it's just like it gives up.

Any suggestions as to what to look into? Relevant info is 99 9-5 2.3t, automatic, 97,000 miles.

Thanks!

sounds like you might be in the early stage of fuel pump failure. A good tech can measure the current draw on the fuel pump - a nice even sine wave is OK, large dropouts are not.

I had thought about the fuel pump, but it had been suggested to me that it was more likely for that to fail more quickly -- I do see that being a possibility though, especially seeing as it seems to happen more often when the fuel tank is low.

Re: the transmission fluid, I bought this car used a few months ago and I am not really sure about the fluid -- it's probably worth having changed sometime soon anyway. What's the work involved in that (and thus cost?)

I'm not suggesting you need to change it.............yet.

Just, what is the colour and level like?

I really am unable to check it. I could at home, but I am at school and lack any sort of tools. I have to have my brakes checked (weird vibration issue), so I can always ask them to check out the ATF at the same time.

Thanks

Ah, I will check that -- I am still very much in the mode of my previous car (MKIV Jetta) whose ATF fluid was a bear to check.

Thanks

Air filter is good as of the last checkup, I'm not sure about the O2 sensor -- is there an easy way to check?

Not a way i know of.
just replace it.

They are cheap ($30) and easy as pie to replace (one bolt, four wires)
the car will idle better and will get better economy.

I checked the Transmission fluid, and the level appears good and the color was a dark-ish (though still very recognizable) brown. I'm not sure what color it is supposed to be, though.

The auto gearbox oil should be changed at your mileage anyway, so it is worth doing. It will be fairly cheap to get done. Just drains out and then top up. Really needs again at a later date as you cannot drain out all the oil.

My engine cut out (in my 9-5 2.3 auto) the other day when I put it into reverse. It was only 15 minutes after I purchased it :eek: so I thought it had a problem and I'd been caught. But it hasn't done it since. I'm now in my third week of ownership.

This has happened more than once to me (not sure if that makes a difference) -- probably 3 occurrences total, once it did it twice in a row.

I don't know if this has anything to do with it, but the car also seems like it doesn't always have as much oomph as I'm used to it having -- I suppose this could be due to the cold weather, I'm not sure.
