D Series mystery? (potentially a noob question)

By Ahkten
- Sat Dec 03, 2011 7:00 pm #283942 I dunno if any of you have had this problem come up, but whenever i go downhill for a long period of time, (I usually switch between third and second to slow down a bit) once im out off the hill and back to flat road, my car has a bit of trouble accelerating, almost like its choking or is peaked at a certain speed. RPMS don't move, speed doesn't increase or decrease, just continues running.

It'll stay at around 60-80kms and not go any faster. then after a few seconds, it'll just go back to normal.

It's almost like someone has a rope on the rear bumper of my car, and lets go for me to continue building speed. It ONLY happens during DOWNHILL though.


Has anyone had or currently having this issue now?

Thanks in advance,
Nick

- Tue Dec 06, 2011 3:32 am #284314 How much would 3 years difference make on an engine? (stupid question, i know). Mines a 92 DX and my dad's is a 95 DX. I've never felt or heard of him having this problem. Was/is he lucky to not have it? Or will it eventually happen to him?

Edit: Obviously KMs make a difference. But mine has less KM than his, by about 3K. Im at 244, he's at 247, maybe 248.

Thanks so much for the help guys!

- Tue Dec 06, 2011 6:55 am #284333 Km/mileage will only make a difference if both the cars where driven the same way. If your pops drives like a granny, but you drive like your in a F1 car touge racing in the mountains sitting at 16k rpms 24/7 then your lower mileage motor will definitely have more wear and tear on it. Or even if hes comutes on flat roads and you go up and down mountains, its gonna come down to how hard the car is/has been driven not necessarily the mileage. Although their may be some internal or external differences in the design of the motor/car made over those 3 years, but I cant think of anything, that corresponds with your question.

Using compression to hold back your car on a long hill will push a little oil past the rings.
When you get to the bottom of the hill, your engine has to burn off that oil and clear your cylinders before you get a clean combustion chamber and full spark again.
Try just using your brakes down the hill without using compression and I would bet you don't have the stumble and lack of power at the bottom.
