You asked for some emails, so here’s one from me. It may not be Piston Slap worthy, but it’s got me confused. Here’s my problem:
I have a 1998 Nissan Frontier. 150k miles, 2.4l four banger. It threw a Service Engine light on me the other day. The code is a P0301, i.e. cylinder #1 misfire. Figuring it was a spark plug issue, and since I was about due for a tune up anyway, I replace the plugs, wires, distributor cap and rotor. I cleared the code with my scanner, and….it came right back. I did a little creeping on the Nissan forums, and the consensus seems to be that this results from clogged EGR passages. So this past weekend I decided to clean them. I was lead to believe that this would be a cake walk. All that was required was to remove the set screws between the intake runners, spray some carb cleaner in there and scrub them out. Easier said than done. Removing the screws was not too bad, but putting them back in after cleaning was nigh impossible. 5 hours and sawed off 8mm Allen wrench later, I had the plugs back in. My truck ran great! For 20 minutes. Then the code came back. Now I’m pretty much flummoxed. The way I see it, my options are:
1. Remove the air cleaner assembly and manifold screws again and try cleaning them more thoroughly with a pipe brush and more carb cleaner
2. Try something like Seafoam through a vacuum hose. I am reluctant to do this as I’m not 100% sure which hose to use and opinions on Seafoam are mixed
3. Take my vehicle to a mechanic for a more professional diagnosis. I do have access to a reputable independent mechanic who specializes in Nissans and Toyotas
So, what do the B&B think? Anyone else had this problem with a Nissan KA24DE 4 cylinder?
Thanks for your help. (Read More…)

I always enjoy reading Piston Slap and want to ask about my truck, a 2007 Nissan Frontier with the VQ40DE (4.0L V6), 6-speed manual, and 42k miles. Sometimes the truck will rattle while accelerating at around 2200 RPMS. This only happens after completing a long freeway run (an hour or more) and occurs in every gear regardless of throttle position. The noise goes away after a few shifts or always after the truck has been shut off and restarted. It has been going on for 6 months or more (it took me that long to figure out how to duplicate it) and doesn’t seem to be getting any worse, plus it doesn’t trip any check engine lights. I can’t imagine how to replicate the noise for the dealership service department. Any ideas? Computer issue with the air/fuel mix maybe?
I have a friend who just got her PhD and is moving to Texas for her post-doc. She has never owned a car, but now needs to get one so she can go out in the field to do research. I’ve agreed to help her find something used, probably a small manual-transmission pickup truck. Needless to say she’s not a car person at all, just wants something inexpensive (under 5k), that she won’t have to worry about too much. I’m recommending something after 96 or so, to get the R134A A/C and maybe a few more airbags and safety features.
I have owned a couple Nissans (Frontier and Rogue), and a Toyota Tacoma, and my brother owned a Nissan Frontier, all were mostly problem free. I also had a 91 Ford Explorer before that, which also gave me few problems up to 200k miles.
Given my experiences, I’ve been thinking Tacoma or Frontier for my friend, I think they will be more reliable at the high mileages she can afford. But looking in the local (Phoenix, AZ) Craigslist – By Owner section, I see that Tacomas are relatively more expensive, older Frontiers are cheaper but less common (many are also heavily modified), and there seem to be lots of less expensive Ford Rangers available.
Do you agree with the 96 or later idea? Or do you think something older could work? What about the Ranger’s reliability as opposed to the imports? Also, are there any other models with a proven track record she should consider? And finally, given that a 10+ year old truck with over 100k miles is going to need maintenance no matter what, what about parts availability and ease-of-maintenance between the brands? (Read More…)
About a year ago, Nissan’s response to nose-diving truck sales betrayed some serious ambivalence about chasing the profitable-yet-dangerous segment. Its first plan was to rebadge the new Ram, but that deal has fallen apart in the wake of Chrysler’s shotgun wedding to Fiat. At a loss for options, Nissan canceled the Quest, QX56 and Armada and started tooling up its Canton plant to produce commercial vehicles. It looked like Nissan’s days in the truck market were over. Now, USA Today reports that Nissan is developing a new full-sized pickup (and SUV) after all. By itself. Who’d have thunk it?
