| ML320 Issues, Need Help
Need some advice on a couple of issues I am having with my 2000 ML 320:
1. The aux fan fuse is blown, how hard is this to replace, can I fix it on my own (i am a novice)?
2. My engine has a rough idle and makes a loud click noise when the hood is up. Idle is not bad when in neutral. Somewhat worse when the a/c is on.
I just got it back from the shop for having an engine sensor fixed, the dealership claimed that may fix the idle problem (big suprise, it didnt). The dealer also said it may be my choice of fuel. Anyway, would a fuel additive help or an injection cleaner or gumout products? Thanks for any help on these issues. I appreciate it. |
