mark d chip..stumbling

[richardkeith97]

i just installed my mark d 19# 93 octane chip. the cel finally just stopped coming on after a couple days. it drives great but doesn't idle good. it stumbles a little when i give it gas. i read that this is a common problem. just wondering how long to wait until i start fixing stuff like the 02 sensor and the coolant temp sensor? car ran great before and had no issues. i've gona through about a half tank of gas. thanks

non-mark d, but i had stumbling/afr issues and it took an entire tank of gas for the dme to work them out.

I ran two tanks of gas through mine and no problems. It was pretty smooth to begin with, but smoothed out a bit more once it adjusted so-to-speak.
