    When is the last time you changed the fuel filter? Cold weather can freeze wet dirt in the filter and starve the engine of fuel. The filter is under the floor of the passenger side rear seat attacked to the frame.

    2000 "S". I did my fuel filter @ 70K. The truck did not run any better but I felt better knowing it was changed out. Closing in on 91K. Last day of June, My tropper will be 3 years old. Cheers to all!

    Beer and I got ours at almost the same time, and I drive A LOT and he's nearly doubling my milage!

    Had it changed once - somewhere between 50k and 70k miles, so it has been between 6 and 18 months. Didn't notice any change in performance after it was changed.

    Is 50k miles or so a reasonable fuel filter change interval, or do you folks recommend more frequent? I don't recall what the owners manual says.

    hey Emiura. Did you get the 60K miles service at the dealer or independent mechanic? It seems a good price for 60K miles service since my local Isuzu dealer here at Salt Lake City wanted over $500 for 30k miles service.

    Has anyone replaced the stock air box and air filter with the Calmini high flow air filter system? Any noticable improvement on MPG and hosepower?
  • paisanpaisan Posts: 21,181
    "high flow" you know you are likely going to be sucking in lots of high flowing HOT air if you do this! Not to mention that your SUV then becomes a lot less U cause you're likely to suck in water....

    Oh yeah and it doesn't help in HP/Power either IMHO.

  • I agree with Mike. A high flow set up increases your potential exposure to water. I opted for a K & N drop-in filter. I don't like the idea of an exposed filter under the hood. On several occasions, my filter box has been covered with mud due to off-road conditions.

    If you really want a high flow set up, you can make one for much less than the Calmini** kit. K&G has universal filters for use in this application. I remember reading a do-it-yourself write-up on this topic. It included a filter, a plastic pipe and a clamp. I think the article was posted at planetisuzu, but I'm not sure.

    **The salesman that handles Isuzu for calmini is arrogant and pompous.IMO I hate spending money with them.
  • satysaty Posts: 23
    hey Lee. Did you go with the K&N replacement filter then? If you did, how the performance of your trooper?
  • Yes I use the replacement filter that fits in the the OEM filter box. To be honest, I cannot tell a difference in my engines performance.
     
    The K&N filter is extremely durable. I like being able to clean and reuse it. I have friends that swear by K&N products for performance capabilities, but I think the biggest selling points are quality and convenience.

    None of the auto parts stores in my area stock a K&N filter for the Trooper. They required full payment prior to ordering one, so I purchased on-line. The filter comes "charged" so you can postpone the cleaner/charger kit (a separate item) until later. Most stores keep this item in stock.

    I have the panel filter also. Works great and even helps prevent water from going into the engine. Pulls slightly over 4000rpms but not much IMHO.

    I went to a independent shop, not a dealer. The 30K service was about $260 at the same shop, but that price included $50 discount. I'm happy with this shop.

    One of the Isuzu dealer in my area discontinued Isuzu recently. The other dealer still sell and service Isuzu vehicles, but they let all Isuzu techs go as they are mainly selling Hyundai now. Now my warranty is almost over, I probably won't need dealer service any more.

    Are you in SLC? I remember seeing Isuzu dealer by Hwy 15 in Draper or Lehi?

    I put in the K&N filter drop in and it helped a little for towing a 4000# trailer when the gas pedal is pushed to the floor and stays there a while. Once before the K&N I replaced the air filter with a clean paper replacement and going from dirty fitler to clean filter made a big difference. The K&N says it will maintain a higher flow rate longer even as it gets dirty, that is what sold me on it.
    ..
    I previously installed and removed the calmini K&N exposed filter kit. It has a port on the heavy steel tube for the small hose that was not at the correct angle so I would have had to buy a longer small hose. I did not like the mounting bracket sturdiness compared to the amazing weight of the big steel tube. I ran it in the driveway and decided to remove it right then because the exposed cone shaped filter is right in line with the engine cooling fan such that any water or debris that hits the fan could hit the K&N filter element directly at high velocity. The K&N filter element looks like an oily tee shirt stretched over a metal screen, not enough to prevent a hole from a small stone coming off the fan blade in my opinion.

    Rather than take it to the dealer and be told it is "normal" wear, I took it to a local shop today and told them to take a look at it. Barring anything too expensive, I am just going to have them fix it. The only thing I can think that might have to go to the dealer is if the whole gear needs to be replaced? I still might try to find a rebuilt one cheap and have the local shop put it in. I figure up to $250 is worth it to save the hassle of multiple trips and not great service from a dealer network that is not entirely supporting their product.

    On a related note, my Check Engine light came on during my trip there? At least is was before rather than after.
  • Please keep us up to date on your repair work. It would be great to find an inexpensive fix for the loose steering issue.
  • sbcookesbcooke Posts: 2,297
    The local shop I took it to was able to recreate the slack in steering. However when they got it on the rack and checked everything out couldn't find anything wrong? The gear was tightened properly.

    The problem happens mostly when it is warmed up? So it is probably something inside the ball bearings inside the worm gear, and that I should have the dealer replace it if anything. UGH...I have an appointment Saturday to demonstrate this problem to my dealership and then possibly setup an appointment to have it resolved. Otherwise I will just have to outright pay/tell someone to replace the gear entirely.

    The mechanic said he didn't think it was a safety issue? However I have felt a shimmy at 45-55 MPH since it started and had my tires balanced twice. I can feel this slack offroading, where the wheels and steering moves, but the steering wheel doesn't, as if the gear is banging against either side of the slop?

    My Check Engine code was a "44"? Another thing I will have to have the dealer look at.

    need a short advice or instruction on how to replace the fuel filter in term of brand and thing to look for. My is 99 lux. version. Bought it used and don't think previous owner had replaced it.

    Thanks in advance
  • sdc2sdc2 Posts: 780
    The fuel filter is inside the frame rail, passenger side, in front of the rear tire. Replacement is fairly simple. Before replacing, depressurize the fuel system by pulling the fuel pump fuse and cranking the engine.

    You will still get some gas on you...wear safety glasses.
  • satysaty Posts: 23
    Thanks for the infor. on fuel filter replacement sdc2.
  • satysaty Posts: 23
    hello again. I'm getting ready to replace my spark plugs on 99 Trooper. Any suggestion on brand, level of difficulty and possibly brief instruction? I had changed the plugs before but not on this trooper.
