Have 99max SE Limited. 58000 miles. CEL came on several months ago with EGR hi/lo flow code. Stealership stated the EGR system needs to be completely cleaned including my wallet for around $400. Here is the interesting part. I have noticed the CEL will come back on when my gas tank is approximately 1/4 full and then disappear when I fill it up. Tried a new gas tank cap but the code came back on. Car runs like a champ, smooth idle, no pinging. I always use premium (91+). I would like to try and fix this myself before shelling out alot of $$. I don't quite understand how a CEL light can disappear when I fill up assuming I have a clogged EGR system? At 58000 miles? Anyone else experience this? Any ideas?
Thanks

Thanks. I have heard of their products. A mechanic friend told me about their stuff a while back. Alot cheaper than $400 !!

Ive got the same code. It'll turn off on the hwy but since most of my driving is in the city it's usually on.
