I have had my truck (2005 Nismo Crew Cab) since the end of April. It now has 10,000 miles on it. The check engine light came on about 4,000 miles ago, so I used my code reader, and I read "Misfire on Cyl. #2) So I cleared it. It came back on a few days later, so I cleared it once more. Again, this time a few hours later. Then I left it on until the weekend when I could take it in. The truck would sometimes shake pretty rough at startup (warm or cold) and melo after 30 seconds or so. Well, I take it in, they replace the injectors (well, the 3 on that particular bank of the engine with cyl #2)

So, I get it back, it works nice, runs great. Well, not even 3 weeks later, same symptoms, shakey at startup occationally and I keep getting the same code thrown. I am about to take it in for the 2nd time in less than a month.

Anyone else have this problem?

interesting. probably hate to do it, but probably got to keep going back to the "stealer", until they acknowledge the root of the problem. Das Y Hard!

Good luck with that problem and please post what happens, this is very interesting.

Well, I have got a few new problems to add today. Im so pissed with these problems. I love the truck, but the problems make me not want it anymore.

Today I was driving on the freeway in SoCal (Southbound 405) and it wasnt hot out yet, still pretty early, about 11am, and with our crappy weather we've been having, the mornings have been a bit cooler. Anyway, so Im goin about 75mph, and I just happen to glance down at the gauges and see the temp is almost PEGGED @ H. I was like holly S**T!!! so I start slowing down and make my way over so I can jump off the freeway, when the damn thing goes back down to NORMAL?!?!?! WTF??? So then I was like, OK, and kept going. I eventually reach my destination, and am stiitin in the parking lot with the engine running, and watching the temp gauge slowly climb up up up. I just turned it off.

After about 4 hours pass, I pop the hood, check the water/coolant levels. NORMAL?!?!?! Why am I over heating? But get this, its inconsistant with its overheating. Sometimes it will, sometimes it wont. Stopped, street driving, freeway driving, it would happen during any of these conditions.

I had noticed in the past few days that the radiator fan stayes on, all the time. Even if I go out and start my truck 1st thing in the morning (been sitting all night) and the fan would immediately turn on with the engine.

Another problem is my A/C was crappin out on me today as well. I had it on MAX A/C for a solid 20 minutes to see if I could get it to turn on, NOPE. It eventually came back on. Then I turned it down to the #1 Fan setting and turned MAX off. Thats how I usually use it. Either on #1 or #2. I thought that it might have froze, but the compressor wouldnt click like it normally does when I turn it on.

I think Im havin really bad luck with this think. Im taking it in this weekend. I'll keep you guys posted of problems or fixes.

I don't know what the '05s have in them, but my '01SC had a single core radiator. The same thing happened to me at 45K (flushed at 30K), the temp gauge just pegged.
I did all the normal stuff: checked the fluid level, flushed it out, r&r the t-stat, replaced the cap. Nothing worked.
Finally I had the radiator cored. It was plugged! This worked for about a year, then it started to overheat when I turned the a/c on.
By now I knew how to check for a plugged radiator (simply feel the cores of the radiator, you shouldn't have any cold spots, the entire surface should be evenly warm/hot). The only thing that fixed it was a new radiator. I got a 3 core from radiatorbarn.com and that took care of it.
A word of caution: when it overheats, turn the heat on full blast. This'll help cool the engine. But don't do this for too long or you'll end up replacing the heater core, and you don't even want to go there.
But you're still under warranty. Get that thing to the dealer and have them service the cooling system, but check for a clogged radiator first, by feeling it. If it's clogged, get them to replace it, under warranty. Like I said, a coring only lasts about a year and a new rad. from the dealer goes for $425+.
See my post "I guess this is a mod" in the proformance forum.

i was looking under the hood today and noticed that the belt driven fan was spinning awefully slow being that the engine temp gauge was very very high. So that leads me to believe the fan clutch is bad, hense the reason the electric fan is ALWAYS on.

When you say electric fan I take it you're talking about the a/c condenser fan. I think this fan is always on when the a/c is on.

I thought my clutch fan was my problem, too. Went so far as to order one at the dealer when I realized I had a clog. Could be the c/f though.

I'd still feel the inside surface of the radiator, when it overheats, just for the info., and then let the dealer sort it out. Overheating can cause all sorts of future problems.

I have had many years experience with cars. I did check the radiator, it seems fine. The fan clutch is temperature activated, and when the car is in the overheated state, that fan clutch should grip like a mother fu**er. but you can seriously stop it with your hand because it is spinning at about 100 rmp. I had used a oven mit to stop it at first, but when I realized how easily it stopped, you can use your bare hand. I also had the a/c off when I was doing this and that fan is always on, it acts as a backup cooling fan from what I've been told by the guy that worked on my truck at Cerritos Nissan last time.

Oh, BTW, it completely stalled on my today, gas florred and still wouldn't move. Did that for about 40 seconds or so.

You stoped it with your hand! That"s not good. New clutch fan time. That thing should be roaring when the engine's that hot
They must've changed the elec. fan for '05. My '01 only runs the fan w/the a/c on.
Was it overheating when it shut down on you? That truck's starting to p*** me off, so I can guess how you're feelin' about it. I'd take it to the dealer, make them get me a rental, and tell them fix it or keep it.
Keep us posted on the results.

Took it in last night. And one of the sales guys was there when I pulled up, he says the following:

Him - "Hey hey, Fontier, great trucks huh?"
Me - "Yeah, but this one has been a pain in the ***"
Him - "No, No, they were tested in Arizona for 24 hours strait with no problems"
Me - "Well aparently not this one" <im in no mood to talk to a salesmen about service, he doesnt know anything>
Him - <walks over, looks at it, peeks in the window and says> "Oh, you have an aftermarket radio installed, thats the problem. They arent designed to work with those kinds of radios. If you wanted a better radio, you should have ordered the Rockford Fosgate package"
Me - "Hahahaha, no. That has nothing to do with it."
Him - "Well, the service guys will tell you the same"
Me - "Well, its been here for service before and they didnt say S**T!" So that must not be true <as im walking away laughing at him>

Whats an ***, stupid salesmen.

Man, you didn't say you had an aftermarket radio. How are we gonna help you if you don't give us all the info? Probably one of those cheap models that puts too much load on the alternator, causing it to work too hard, and overloading the engine. That'll do it every time. Did you try turning the radio off when it overheated? :)

Good luck w/the service guys.

You know, you should look into the lemon law for California... I'm from San Diego... unfortunately I don't live there anymore, but hey... Cali has some serious Lemon Law addendums <-- Did I spell that right?

I bet you could force the dealer ship to trade your truck in for a brand new one with the same payoff. Might be something to look into.

Sorry to hear about your problems. Hopefully it's nothing major and will be an easy fix. I have had no problems yet with mine...(knock on wood)...It seems to me like it's some weird electrical quirk...

Be sure to keep us updated on the problem and the outcome.
