Hello, i have an 1998 Forester (non turbo) and i will like to know why my idle rpm is at 500 rpm ? It is too low in my opinia.. and no idea what can cause this. It is like this for 2 years since i bought this car...
Can anyone tell me what to check, clean, whatever ?
It could be that the cable has strecthed out over the years. The idle on the 98, assuming it's cable driven, is very easy to adjust. I did it on my 02 WRX. Someone else should chime in though, I don't have any pics of the linkage to really give direction.
Other than that I imagine there are several things that could cause it. Have you been up to date with maintainence items? When was the last time the air filter was changed or the MAF cleaned? Dirty injectors maybe?
Is the trans manual or auto?
I have a 2003 not a ‘98 but idle speeds for the ‘03 are
MT 550-750 RPM
AT 600-800 RPM
I’m thinking that ’98 specs should be the same. Also the dash tach may not be 100% accurate. Connect it to another tach and see what it reads.
Are you sure it's at 500? The markings on the tach are a little misleading, the lowest mark is 500.
Bumping this up... totally confused but is the lowest mark actually 500?? That would mean that the first set of increments is going up by 100. I've never seen that before but I would be running at the right idle (700) and I shouldn't worry about it haha.
I'm sorry, I was taken away by other issues for awhile. My car is a standard (manual) transmission. I would still like to know how to set the idle. It appears there are two cables that control the gas feed. Which one is the correct one to adjust?
