Auto RX???
Auto RX???
I have a 2001 S430 with 130000 miles. It has rough idling. I came across a product called Auto RX. Has very positive testimonials. Has anyone tried it in S 430's? Give me your thoughts, please. Thanks.
no.
There is a reason you have a rough idle, and autorx or any other snake oil products are not going to fix it.
First you'll need to determine whether its a spark, fuel or compression problem, then you can apply the appropriate solution.
