    2000 Expy engine rattle.

    it's at idle when I hear it and it's at the front of the motor. Mileage I'm not really sure because my odometer stopped working soon after I bought it but I'd say it's probably sitting right at about 110,000

    2000 Expy engine rattle.

    I noticed today that there's a rattle coming from the motor. 5.4 liter no check engine light, no gauges acting crazy. I'm assuming something is loose. Was hoping someone might of had the same issue. Thanks.

    Rough idle after replacing alternator (??)

    I talked to someone from Ford today and he told me to check my PCV lines/valve. That'll be the next thing I check. It's just frustrating!!!

    Rough idle after replacing alternator (??)

    Stamp11127- I had the Alternator checked.... No load - Loaded 14.38V. 14.56V. I read the owners manual and it says to "re teach" the ECU after resetting you need about 10 mins city driving (stop and going) and about 30mins interstate (non stop) which I haven't done yet. I just don't...

    BadRonald- it's alittle over a year old. I had the battery and the alternator checked earlier this week, both were good.

    Anbaddon, the alternator had plugs attached to it when I bought it, they were just cut off the other vehicle so none of the connectors were exposed. I also cleaned the MAF sensors this morning as well as checked the belt and its tight.

    Rough idle after replacing alternator (??)

    Ok so earlier while it was idling I checked all the vaccum lines nothing seemed to be an issue there but I noticed the interior lights were kind of dimming in and out.

    Rough idle after replacing alternator (??)

    Thanks Bad Ronald. I dunno, is it safe taking advice from someone called "Bad Ronald" lol! Anyways I'll try the 2500 RPM thing in a bit. I changed the Alternator Monday so it's been driven briefly since then, just maybe not enough.

    Rough idle after replacing alternator (??)

    So I change my alternator and now I'm getting a rough idle. I heard that you have to give the ECU module time to reset it's self after disconnecting the battery and once it does it'll straighten out. Any truth to this? If not any suggestions?
