My renix 2.5 tbi. (Wrangler) needs 0.5% co it has around 0.6 % after warming up for a few minutes. Then when running stationary and standing still, after 6 or 7 minutes it rises to 6%in a few seconds 🤯. I know i have a bad egr.. but could that be the problem?
Checked CTS , MAT
replaced: MAP.
Thanks in advance.
