Weird idle issue

I have a 92 camaro 3.1 with a 5 speed and when driving then coming to a stoplight the idle will go up while sitting after like 10 seconds until the check engine light comes on then after a few seconds it starts to idle down. Any help would be appreciated. Iac and tps have been replaced.

Re: Weird idle issue

What code(s) are you getting with the check engine light?
