Tune up
A 1998 Honda Accord is tuned-up by replacing the spark plugs, fuel filter, air filter, and cleaning the injectors. Changing the motor oil and transmission fluid are often changed at this time as well.
A 2004 Honda Accord should have a complete tune up every 100,000 miles. The oil needs changed in the car every 3,000 miles.
Plugs, wires, rotor, cap, pcv valve.
Needs a tune up?
A Honda CRV tune-up should include replacing the spark plugs and spark plug wires. The tune-up should also include changing the oil and the oil filter.
Try doing a tune up. Change sparplugs,wires etc.
tune it up
There are just too many of the one or two of the devices on the car that would be causing this. Go to a tune-up shop.
If the engine is in good tune and running as it should, and the tires are inflated to the correct pressure, you can expect 20-21 city and 26-27 highway 23-24 combined on a 4 cylinder A/T. On a V6 A/T expect 17-18 city and 24-25 hignway 20-21 combined. On a manual transmission car add about 1-2 mpg.
I have a 1995 Honda Accord EX four dour stick shift with 222,500 miles. I get just over 32 miles per gallon on the highway (I know!). My brother works at a Honda Acura shop and we keep in good shape with regular tune-ups, oil changes, etc.
