I have a 2008 Jeep Compass Sport. 2.4, traction control
My Jeep is a "Southern" vehicle. The weather in New York was very cold and snowy the whole month. Many days when I'd first start it the battery would slowly turn over for a brief second. Never had issue with it not starting.
I took a trip from SC to NY at the beginning of January. I returned home this week. A few times through out the ride I smelt either a sulfur smell or a skunk smell. Thought maybe it was outside, however it happened a handful of times at different times.
10 hours or so into the drive I pulled into a rest area. Jeep was running great as it always has. I shut it off but left the radio on the Syracuse game. We were at the rest area not even 8 minutes. When we got back on the road I was noticing that from 2500 rpm's if I were to accelerate to 3000 rpm's it was drop off and go back to between 2000 and 2500 rpm's. I thought that was kind of weird as I also was worried about a slight vibration but figured it was road/tires. I'm always aware of surroundings.
Roughly an hour later, maybe even less, I accelerated to get passed a truck. I accelerated to around 3500-4000 rpm's. Speed limit was 70. traffic was going nicely
This is where the problem started. a light above the gas gauge came on. a "lzl" light. As well as the traction control light. I had no power above 2000 rpm's and could not go above 55mph. I tried the slapstick (I never use this) and it would not come out of 6th gear, it seemed.
When I was able to get to a gas station to assess the issue I reluctantly shut it off. At idle the rpm's would fluctuate and sounded overall rough. Also, the sulfur smell had returned, heavily. After not finding too much help in the book, and my insurance was closed for the night, I decided to try and limp it as far as I could home. After all we were no more than an hour and half to 2 hours from home at this point.
To my surprise there was no problem at all. She was running fine once again. Except for what I thought is/was a small sluggish to it, and sulfur/skunk smell. I was able to get home just fine.
I stopped into Advanced yesterday. They run their diognostic check and the code P2173 appeared. Something to do with Electronic Throttle Control. I've found that other people have had similar issue, however nothing substantial.
has anyone had this problem, and does anyone have any suggestions? We do most of our own vehicle maintenance at my house. A shop if needed is good however are very pricey.
Thanks in advance for the much needed help!!!
