Some cars have faulty check engine lights. IF you already had the car checked out then you should be fine. If not do so. you would think that all the money we spend on cars the would have worked the kinks out.
Driving at 50mph or above what causes a loud knocking clicking sound during acceleration?
it goes like 50mph or higher
Air Conditioning is a unit connected to the engine... when ac on, it connects to power from the engine to make it operate... it uses power making the engine work harder, consuming more gas. I've heard from research that driving less that 50mph(or 40 i think) with windows down is more fuel efficient.. while driving 40 or 50mph + and having the ac on is more fuel efficient.. because of drag from wind.
200 miles
About 45mph maybe 50mph for .21 engine
Plugged muffler ot cat converter
It will take 10 hours and about 15 minutes.
depends on what litre the engine is
You may have a rear tire out of balance.
50mph = 80.47kmh
Most likely your alignment is out of whack or bad struts. Could also be the wheels need balancing.
The .21 engine goes about 45-50mph. I dont really know much about the .28 engine but im guessing it could go around 70-80mph.
