Clogged air filter. Clogged catalytic converter. Failed vacuum advance on distributor. Failed fuel pressure regulator on fuel injection rail. Failed thermostat in cooling system (cold engine rich mixture) Bad spark plugs. Dragging brakes. Stuck parking brake. Low tires. Timing on ignition wrong.
Mechanical problems in a used van could be similar to mechanical problems in all used vehicles. Common issues would be alternators, transmission, worn out belts, egine trouble.
A new service calibration for the powertrain control module was released to address a sag condition, as well as others. I recommend receiving this calibration from the dealer. There are any number of internal transmission problems that could be related to this concern, as well as engine mechanical problems or ignition related problems (spark plugs) that could cause this condition.
It could, yes.
Depending on mileage--could just be a sign of engine wear Remove oil sending unit and replace with mechanical gauge to determine actual pressure
You could use it to find the answer to basic mathematical problems. It's like a simple, mechanical calculator.
Yes
Yes, it can. Pancreas problems can cause fluid and air to build up in the stomach, which can cause severe vomiting.
Solar winds are the cause of the norther lights (and the southern ones too, but the name escapes me). Also solar winds could cause communication problems with satellites, which could cause T.V. problems, cell phone problems, GPS problems, internet problems, etc. etc.
Yes it certainly could cause bad gas mileage especially if it is plugged up or if your car's oxygen sensors readings are faulty.
This engine was designed to be run with a 5w 30 oil. A 20w 30 is a thicker oil and could cause problems such as reduced mileage and even engine harm.
Yes you can but it can cause problems.
It could cause destruction of homes, city buildings. And if big enough engulf interior
