Starting Car on Small Incline...

I just noticed this but the car starts up just fine on a flat surface with hot or cold weather. But I went to a friends house who has an elevated driveway and everytime I get in the car to leave and try to start the 8, it hesitates for about 2 seconds before starting.

Any ideas what it might be?

Don't park on an incline,,JK. Sounds a bit odd to me. Don't have an answer.
Speculation? Not really anything comes to mind.
Unless for some reason the fuel is creeping back towards the tank and leaving a space of air between the fuel pump and pick up line in tank. I doubt it though. Air would have to get in to replace the fuel. And you have no fuel leaks.
Oh well.

^yea that's what i was leaning twoards as well..but it doesn't seem like that would be (as per how does the air get in)...to be honest i could guess at a lot of different things that could cause this...but with out looking at the car and messing around with it...i dunno.

what year is your car..if it's under warrenty take it to a dealership. hehe if not make friends with a mechanic in your area who will check it out for free

to recap from what you've said...i'm leaning twords a fuel delivery issue..b/c the car has no issues on level ground just on an incline. But not sure the exact cause (or even if it is a fuel draining to the rear issue) with out checking it out.

is the front of the car pointed up..or down....or does that not matter when it cranks a few times? is it temperature dependent too? does the amount of tiem the car has sat on the incline play into it any (only after a few hours liek that or a few sec.'s)? things liek that....we can help you more if we had more specifics.


hmm..ok that's a lot of babbling..hope i stayed on track..if not sorry. lol

Or are you just depressing the clutch?

I will be happy to oblidge w/specifics..lol

I park w/the vehicles nose on the incline. Its weird though cause when I park and leave the car in neutral and then start it up again it starts fine. However, when I start the car in gear, it has trouble starting.

Both, I usually just leave the parking brake engaged until the car has started then release it.

I actually found that, when I had the Int-X installed, the car was harder to start on an incline.
WTF?

It happened again today when I went to my friends after work. When I left work, car started no problem. But when I left my friends, started it in gear, it was more like 4-5 seconds.

I wonder if anyone else has this problem.

ECU thinking? Ahh.. out of control, must shut down, apply DCS, TCS a wait a minute..
tires not moving, I'm ok to start the car now.

Hell of a good question if others are experincing the same thing. Go to West coast section and see if you can find member in San Fransico.

Im in az so maybe ill try there, unless there is someone from san fran who knows?

I thought it was the battery at first but that was ruled out because starts fine on flat surfaces.

The only thing I can think of is the clutch not fuly engaging the swithc to allow you to start the car.

Maybe, i didnt think of that. Maybe because im at a steeper incline im not pushing the clutch as far as I need to? Im going to try that tomorrow and see what happens.
