Car was super bogged when I got it with 74k did the following work and ran 300% better. Problem is after it sits all night, it wont idle just bogs down. After about 2 mins of driving its fine, but then surges at idle from 1k-2k. I have read some similar threads but it seems they all end up with different fixes. Has anyone ever had this same issue, and know the fix? EGR? Anyway thank you guys for listening to me probs Thanks Chris
