Sport. It changes the shift pattern of the automatic transmission. You can turn this on or off.
The S light means you have the transmission in Sport Mode. This will cause the transmission to delay shifting to a slightly higher RPM.
If the check engine light is flashing it indicates that a cylinder misfire has been detected.
Engine miss at idle. Can be caused by vacuum leak.
I have a 1990 Honda accord ex and my check engine light the car goes form a high rev to a low rev when I first turn on the car. Is this a vacume line problem or a voltage problem?
remove backup/radio fuse under hood
The S light refers to sport mode on the trany. The sport mode changes the shifts slightly in an automatic trans. The car will perform better in s mode in stop and go traffic. The button to change to S mode is located on the shifter.
The 1990 Honda Accord does not have a cabin filter.
did you look in the owner's manual??????????????????
check your oil pressure.... that's what that light is for. if oil pressure checks out the replace sensor
