Morning Scotty! I love your YouTube videos! They have encouraged me to start working on my own car! I have a V6 07 mercury milan with just over 150K miles and found out my oil pan gasket has been causing my oil to leak. I was riding home from work last week and out of nowhere my car began shaking and my AC stopped working (mechanic said I need to purchase a new ac compressor and radiator fan to fix the ac problem - I bought a used compressor and new radiator fan from 1aauto). It's way too hot in Texas to ride without AC! My check engine light appeared and I took the car to O'Reilly for the check engine test. I was told I needed to get 1 ignition coil which I did in addition to new spark plugs however the car was still rattling. I even went ahead and purchased 6 new ignition coils from 1aauto and installed them myself and the freaking car is still rattling. The rattling is extremely bad when the car is at a complete stop. How should I move forward?! Based on the info I provided what do you recommend I do. Should I continue trying to figure out the root of the problem or should I move forward and purchase another used car? Thanks for all you do Scotty!
