Hi All! New member from Arizona here...

Bought a 2007 Outlander 2WD (was a dealer return) in 2008, and don't get me wrong, it's been a great vehicle up until lately. Had the coil pack and usual tune-up work done at 60,000 miles (normal warranty work, right?) and everything seemed fine. Shortly after that, my wife (who is the primary) driver has started complaining that it doesn't have the same "pickup" that it used to have. Before the tune-up, you could barely touch the pedal and you'd be in passing gear almost instantly. Now you have you stomp down on the throttle to hit passing gear, and there seems to be a half to one second lag before it kicks in. I'm also noticing that the gas mileage is down from where it normally was. Used to hit 30mpg quite often when driving the freeway; but now am lucky if I can get 25mpg.

We've taken it back to the dealer a couple of times, and even the service manager has taken it home and driven it for a couple of days, but all we get is the same result: Everything is in working order and we can't find anything.

I'm finding it hard to believe that our Outlander has suddenly flipped a switch and turned into a dog so suddenly. We've performed all scheduled maintenance, but still no real answers. Is there anyone who is experiencing a similar issue out there?

 

How many miles are on it now? Was there a problem with the coil packs at 60k?

Surely you aren't rocking the OEM tires by now, what kind did you put on? When we bought ours, we'd get 28 @ 72mph on flat interstate (texas I-35) when we are on the OEM Geolanders. We put some LT rated Bridgestone Duelers and we dropped to about 24 just because they were heavier...much heavier. I won't make that mistake again!

only other thing I could think of is to pull a spark plug or two and see if you have carbon build up. is it consuming any fluids? Do you keep up on your oil change maintenance when you should? I'd be curious what a compression check would give if all else fails.

 

OK... Let me see here...

Currently have 63,000 miles on it. Coil pack was changed at 60K due to computer throwing up an error code reading "misfire in #1 cylinder", right at time of tune-up.

As for tires, the OEMs were replaced about a year ago with a comparable Yokohama model. Oil also gets changed regularly at the dealership. Not consuming any fluids or having any leaks that we can find.

The plugs were changed at the same time the coil pack was switched out. Running a compression check may not be a bad idea. Am also debating if the idea of taking to another dealer's service dept. could make a difference.

 

well...I wonder if you have a vacuum leak. My ranger had a pretty sizable leak when i got it (major reason why the lady gave it to me in the first place). The engine would idle normally for the most part...but when you hit the gas, there was a sputter, a lag, then it would spin up. Also the air would come out of the defrosters only...defrosters in the Ranger are run off of a vacuum line...a good indicator for me that there's no vacuum in the engine compartment. After 5 years, I wouldn't think the lines are rotten by now...maybe a tech cut/bumped a line while doing the coil packs.

 

I know you said your Outlander was working fine at first, but there is a TSB related to throttle hesitation on 2007 Outlanders. Below is a link from this forum that talks about the TSB.
