So let me start by saying I've read this post (http://jeepgarage.org/showthread.php...643#post670643
) and this post (Anyone else think the hemi is underpowered?
) and several others, but I've found very little help, so now i'm asking you...
So, first off, I have realistic expectations when it comes to Jeeps and performance. This is my 5 GC so I'm well aware how they run. I'm not comparing it to Range Rovers or anything else. I'm comparing it to itself.
Last week, 2011 Overland 5.7l experienced something wierd. I didn't think much of it but early in the afternoon after drive for a bit, I was coasting to a stop light when the dash dinged and the VIC said ACC(cruise) is disabled and FCW OFF. It lasted for about 15 seconds, then everything went away and acted normal.
However, since then, this thing has been very sluggish. I realize it's not a fast vehicle, but it's always been faster than this. I've got 16k on it, so I have a bit of experience with it. So, the sluggish response is only once the vehicle is at operating temp. Otherwise, it's fine.
Here's the description of the issue. When accelerating from a dead stop, full throttle, the RPM climbs very slow (or much slower than it used to). It actually feels very similar to when traction control kicks in while in slow mode when it retards torque to prevent traction loss. The same feeling happens for example when turning right with some speed. Meaning when I cost through a light while turning right, normally I could hit the acceleration and feel some torque in the gear I'm in. Now, it's extremely low power until I hit the gas hard enough to where it downshifts, possibly all the way to first. Never had to do this before. One more important detail, the torque is extremely low from idle to about 3k rpm, at which point the power starts to kick back in. Also, after testing it for about a half hour, replicating the behavior everytime, I noticed a strong fuel odor, much like it was running rich. The smell was under the vehicle near the exhaust.
The dealership has driven it twice now and is telling me without engine codes, there's nearly nothing they can do, they have no idea where to start. I'm very frustrated, I spent a lot on this vehicle and I'm starting to regret it. It took them 6 months to fix a sunroof problem. now what? Meanwhile, I'm getting poor (worse than usual) gas mileage and poor performance. It's actually dangerous, you get used to your vehicles capabilities and now I find myself pulling out into traffic when I shouldn't.
In an effort to help speed up troubleshooting, has anyone experience the same issues and what would a dealership have done to fix it? Mine has already tried to pull codes twice and flashed the PCM, nothing.
Please help, I'm really getting frustrated. I've never had so many problems with a vehicle (that I didn't cause anyway)...
