Gooday, I saw your website and went through it and must confess that its very helpful. Please I have a problem regarding my car A/c, a BMW 525, 1989 model. the Ac was no longer cooling so i went to a mechanic and filled the gas up. it again started cooling , but to my surprise 4 days later, it stopped cooling and blew hot air.
We recently had our 2001 Toyota Avalon serviced by our local Toyota dealership for Engine sludge. 96,000 miles, and we had all necessary service and oil changes over the course of 7 years. This $3,000-$4,000 service was covered by Toyota due to a Class action suit back in 200-2001.
About two months ago the check engine light on my 1996 3.8L V6 Chevy Camaro came on. I went to an auto parts store where they read the code and told me I needed a new EGR valve because mine was only function at 10% of what it should be. Well, my mechanic disagreed, saying the EGR valve should not go bad after only 90,000 miles.
