Greetings,
I'm a new member posting for the first time. I have an '01 4.7 that just hit 210k, almost all highway miles up til last year, and have a couple of questions on unrelated matters.
In the last 6 months my MPG has dropped from 17 to just about 13. I replaced the plugs last fall, but no improvement in mileage. It starts very rough when cold and takes quite a while to turn over. I've thought of changing out the O2 sensors, but wonder if there's another culprit for the difficult starting and rough engine. The fan clutch also revs extremely high when cold. I replaced that about 2 years ago and it's now acting up again. Seems to be ok when warm.
2nd question is a request for suggestions as to how to wire my iPhone to the stock stereo system so I can use the iPod for music. Reviews of wireless FM transmitters leave me unimpressed with going that route. Crutchfield sells an iPod adapter that doesn't work with my version of the factory Infinity system. Ideas?
Thanks for your help. I've been lurking for a few years and realized how helpful you are as a forum and thought I'd better put my money where my mouth is.
