Automobile: 2004 Ford Escape Limited 4WD V6 3.0
Symptoms:
Issue #1: Upon start up, battery light flickers, stays on a bit, goes off eventually after a couple minutes. HVAC will temporarily slow down during this period.
Issue #2: Gauge cluster will do a full sweep, and sometimes will do a partial sweep a few times then go back to normal operation. This happens randomly
Issue #3: Engine runs rough on occasion. Borderline stalling then goes back to running normal. Potentially DANGEROUS at intersections and left hand turns.
Issue #4: NO CEL. Nada. Nothing. Impossible to tell what is wrong.
Issue #5: Cruise control quit. The light will go on when I press it but doesn't engage anymore.
Issue #5: Transmission hesitates/bucks. Usually in high gear under load.
Things I have done to diagnose / cure:
1. Two years ago the battery light was flickering and the battery was slowly going dead. I took it to Autozone and the battery checked out ok. Ended up replacing the alternator and that solved the issue until now.
2. April of 2014 a CEL actually did appear along with hesitations, stumbling. It was cylinder misfire and symptoms generally got worse in the rain. Took to mechanic and he replaced Coil Pack #1 & #2. Ran great until we drove through a heavy downpour about a month ago and hasn't been the same since.
3. I read (here and elsewhere) there could be a grounding issue. I live in KS but this was originally from New York and it has bad salt corrosion everywhere. The bolts that attach the seats to the chassis are actually rusty (odd....).
4. I cleaned the ground(s) & bolts on the following locations with either a wire brush, coarse sandpaper, bench wheel or all three then applied dielectric grease:
a) G100;
b) G102 & G103;
c) G104 & G105;
d) G106 & G107;
e) G108
f) I could NOT find G101
g) I have NOT cleaned the ground(s) behind the dash (G200/201/202/203/205) or under the seat (G300/301) or rear cargo area (G400/401/402/403/404)
e) See Squishy's post for pics: viewtopic.php?f=8&t=1686#p38029
5. A couple days ago (Sunday 9/7/14) I took the vehicle to local O-Reilly's and the battery and alternator checked out fine.
I understand the coil packs are susceptible to moisture retention. Dielectric grease was applied to the boots to prevent seepage but perhaps it is not enough. For the life of me I can't understand why the engine was designed to make it impossible to remove plugs and coil packs without pulling the intake manifold. Absolutely baffles me.
Seriously considering putting a bullet in this one.
I really really could use some help here. I am mechanically very competent, but ELECTRICAL GREMLINS give me the willies.
Thanks!
