Hi Folks,
My first post- you guys have had a lot of great advice I have been using.
Which brings me to my latest issue:
On the way home from a trip to Yellowstone from the Portland, OR area, my truck began to give me issues with loss of power. The details:
2004 Nissan Titan- towing a 20' travel trailer
Ran great from Portland to Yellowstone and all the way through Idaho on the way back.
In Idaho- temps (outdoor) rose and I gassed up on the way into Oregon.
On the hills I ran into in Oregon, I had a surging loss of power where the truck power would seem to waver- unless I kept the rpm under 2k or so. Climbing hills became a lot harder. And it seemed to become worse and worse. In Baker City, I stopped to try to affect repairs worried I might be stuck there.
I checked the air filter- it was dirty and I replaced it. I also tanked up with premium gas and octane booster- worried I had picked up a load of crap gas. The results were great- awesome power again.
For about 60 miles. Then it returned. Pushing the engine above 2k gave this wavering power. If I could keep it below that it would go o.k.
I had used about 1/4 of a tank. I gassed again with octane boost again.
Power was back. Again it ran well for about 1/4 tank and got bad again.
I managed through the mountains. Then I experimented with it. I tried stopping for about 20 minutes to see if just cooling off the rig helped. It didn't. Then I gassed up with just regular gas- bad idea- it ran pretty crappy with the same loss of power right off the bat. It seemed like the more high octane I gave it, the better but only for a 1/4 tankful.
So- multiple thoughts-
1: Did I get some bad gas- am I still running it out or maybe water in the fuel
2: Is my pump/filter failing? when its full, maybe the pump runs better due to being full (cools the pump- I have seen that before with another car)
3: I read about a mode the tranny can go into when its too hot where it restricts the power. this might be the case? But when I stopped to cool it off I assume this would go away as well (as it might with the fuel stops).
Right now- I'm thinking drain the fuel and charge it with good gas and see what happens.
If it still is there- I probably need to change the pump/filter assembly
Thoughts? Help!
BTW- the tread you guys really saved me on was the manual shifting issue with the tip-tronic like shifting. You all said it was a little black wire in the column that would break- I checked and it was BROKEN. I fixed it and it worked great- hat's off !
