idle surge please help

[vtron30]

I know this problem is posted every where here but my problem is a little diffrent than all I have read. I have a 93 eclipse 1.8 manual, and my check engine light came on and the idle bounces from 1500 to 2000 rpms and when I try to drive it it will not go past 2000 rpms in any gear so i can only go about 45mph in 5th gear. I changed spark plugs, cables, put a new rotor and cap, checked the tb it looked fine just by looking at it. when I start my car up in the morning it idles at 1500rpms but when I'm driving I can go past 2000rpm but after a while it wont let me go past 2000rpms and the idle starts bouncing again. any advice would be appricieated

Well since your engine light, is on..
It is on for a reason. So something has to be causing it. And most likely it also has to do with the idle surge. So you can find someone with a reader to read the codes. I dont think autozone will read OBDI (I think that is what the 1 gens are...)
