As the title states. When my car is parked nose down grade overnight in driveway the vehicle fires up but engine shakes and stumbles. This doesn't happen when engine is upgrade.
When pulling out from work the car dips down unto the road. I step on the gas to speed away and no throttle response until vehicle becomes level.
Slam on my brakes the vehicle nose dives the engine stumbles and RPM falls below 400 then smooths out when vehicle levels out.
Does not matter what the fuel tank level is.
Lastly I have slow acceleration. Engine revs normal and clutch is not worn as far as I can tell.
78k on vehicle. Plugs never changed. Fuel system never opened up or filter changed since I've owned it. Bought used at 34k 4 years ago.
Map changed. Throttle body cleaned.
Any ideas? Thanks
