Check Engine light that comes on and goes away when it wants to
i have a 92 sentra se-r with a ve and my check engine light came on. the car drives sluggish when the light is on and it stutters a little in low rpm. when i turn on the car the next day sometimes the light will be off and sometimes its still there. i tried to do the self diag with the screw on the computer but it wont flash. the light just stays solid red. i did notice that when the check engine light is on the fan stays on when the key is on the on postion. can anybody help with this or have any idea what it can be
thanks

You get the codes read at a local place yet? That's your first step.
Sounds like an O2 or MAF issue though, possibly TPS or vacuum issue. It can only be a small number of things. Injectors and spark plugs are the least likely, but round out the list.
