Hey Scotty! ( or anyone else who can answer )
I have a 07 Ford Escape with 209k miles, over the past year its had some issues. Currently I've had a rough idle but the idling rpm is normal, engine mounts are fine, IAC and EGR valve are fine, replaced all sparkplugs and ignition coils, replaced alternator, no vacuum leaks, even new hoses on some, clean air filter; Used 3 different scan tools and not a single code. I'm wondering if it has something to do with the fuel pump or filter but I wanted some advice before replacing another part.(at this rate I may just replace the car!)
some issues are: loud vibration in cabin while idle in gear, especially in R, lack of acceleration, and horrible gas mileage and had an instance where it was sounding like I was going to stall out.
Without a code (and even with one) its could be a ton of different things. changing the fuel filter (if they're replaceable on that model) isn't a bad cheap start. What you really need to do is get it on a good scanner and go through all of the data. It could be anything from clogged cats to a bad sensor not tripping a code.
