pls help with accord problem

[slickrick]

I have a 1986 Honda Accord Lxi. The problem is that after about 10 minutes of driving the pgmfi (programmed fuel injection) light comes on. The cars performance does not suffer, but the rpm gauge registers 1000 rpm in idle instead of the usual 800 rpm when light is not on. Any suggestions on what the problem is and how to fix?

Thank you.:confused:

Find out what code is coming up when the light turns on. Gotta start from there first.
