You are in the Isuzu Trooper
What is this discussion about?
Isuzu Trooper, SUV
Jul 09, 2003 (7:19 am)
I bought a used 2000 Trooper Limited with TOD over a year ago. In the last 3 months I have had a bad fuel regulator, bad Intake Manifold Gasket, a clogged PCV valve, and now the check engine light comes on until I drive over 50 miles. The dealer told me the CE light is because of the gas cap (I read all about that well before hand) and it is NOT the cap that is the problem. I take my car to the isuzu shop here in Joliet IL, is there a better shop anywhere? Or any ideas how to fix this stupid orange CE light? These are all very simple problems and everything has been fixed under warranty, but it getting to be a bit much. I had a GMC Suburban for 10 years before this and had no problems.

unless you have a mega-$ OBD II reader, you can't turn off the light.
And the dealer told me that unplugging the battery doesn't clear codes on OBD II...might make the light go off but they are mandated by federal law to retain the codes even without battery power.
I just wish the damned things gave more information..."Check Engine" is ridiculously vague. Half the time it turns out to be something not worth bringing it in for.
#8125 of 11966 HARSH TRANSMISSION SHIFTING
Jul 09, 2003 (11:13 am)
my 99 trooper recently been shifting harsh irregularly. Usually, the problem exist when shifting from 2nd to 3rd gear. It sounded like the transmission is sliping out of gear. The problem does not occur every time. It happened randomly between start and turn off the engine. Could this be a computer problem? I had my transmission flush/fill by the dealer at 49 or 50 kmiles and now it has 53k miles on it.
#8126 of 11966 Trouble Codes and AT Shifting

Jd36 you can get your codes read for free at Autozone. I suggest you do that and post back as to what they found.
If you only want to clear the codes you can do that too. Here is the quote from the Helm manual - "When a scan tool in not available DTCs can also be cleared by disconnecting one of the following sources for at least thirty (30) seconds". It then lists the power to the pcm or the negative battery cable.
Saty I suggest you get your AT level re-checked before you start chasing a computer problem. The no dipstick design fools many a shop, although I would hope the dealer knew what they were doing. In any event making sure of the fluid level and condition is the first step in solving any AT problem, especially if your are not storing codes. If you haven't read the recent posts here about flushing high mileage ATs you should. I think in your case I would recommend getting the filter/screen replaced. By 50k miles there is a reasonable chance that accumulated grime was loosened by the flush and partially plug it.
#8127 of 11966 My '99 Experience ... All Good
Jul 11, 2003 (7:12 am)
I've been reading a lot here about folks' '99s and their issues. I have to say that we've experienced none of these issues. Our '99 S Trooper has 45k miles on it, so my wife and I just consider it 'almost' broken in...
Our transmission clunks a bit harder on a cold start up on its first shift into reverse or drive, but then smooths out very quickly. We haven't done a power flush, just a drain and refill of our fluids at 30k. We don't have the valve tap or ping either. There is no noticeable oil loss. We're down about a cup of oil at our regular oil changes (around 4k miles). Our experience here in Chicago is that this remains the best truck on the market.
We recently drove from Chicago to Rocky Mountain National Park in Colorado for a week of camping with our three boys. A little over 1,000 miles each way on Route 80 through Nebraska. We got roughly 18 miles per gallon using the cruise control set at 75 mph and having the vent open with some use of the air conditioner. Our three boys are under age 5, so we had three car seats in the back seat and all fit just fine. Space in back was a bit crowded with all our gear, but no real issues. We don't use a trailer or a top mounted box. (Although we did like the rear hitch mounted box carriers we saw.)
Funny thing about Nebraska (well there are lots of funny things about Nebraska ), they don't list the prices for gas, only diesel. So each time you pull up to get gas you get a surprise. The best bet was always the mid-grade ethanol blend 90 octane that was about 4-5 cents cheaper than the 87 octane regular unleaded. (Let's hear it for those ethanol subsidies!)
We had no issues in the altitudes with knocks or pings using the 87 octane gas in Colorado. Our Trooper climbed right up Trail Ridge Road like it was nothing special. Using lower gears up and down really helped as well. BTW, in Colorado, regular unleaded is 85 octane.
In case you haven't noticed, we love our Trooper. If you are considering one as a family vehicle (with apologies to Paisan et al who really use their trucks), this should be on your list.
Its funny, I was reading the Honda Pilot board and a poster there remarked that he liked the Pilot, but it was boring. He then mentioned that he missed his 96 Trooper. He said that he really bonded with that truck, while with the Pilot he feels that it is just an appliance like a toaster.
We are planning on keeping our Trooper as long as possible. And with these trucks, that can be to 250k miles (just venture on over to 4X4 wire's Isuzu Trooper community for proof of these trucks durability).

My 99 has been pretty good, some minor stuff like the intake manifold gasket (twice!), and the fuel pressure regulator, but neither problem really was serious other than the hassle of getting it in to the dealer. I am at 59K miles.
Just check your oil regularly...and I recommend Mobil One.
You shouldn't get a valve tick from a 3.5L, they don't use the hydraulic lifters like some of the 3.2s did.
Interesting comment about the Honda, that is the way I feel about them...extremely competent vehicles, but not exciting or engaging.
#8129 of 11966 Mobil 1 and a 93 Trooper
Jul 12, 2003 (4:08 am)
Would you recommend Mobil 1 for an older (1993) Trooper? I do have the valve tick and have been reading a lot of posts on how to deal with it. How about higher octane gas? I only us 87 octane (cuz it's cheap), would 89, 91 or 92 octane improve an performance in a SOHC engine of this vintage?
#8130 of 11966 Feedback appreciated-2001 Trooper
Jul 12, 2003 (4:45 pm)
You guys really know your stuff, so I would appreciate your feedback.
My vehicle has 27k and I was having a problem on vacation with oil consumption (I do not tow). 6 quarts in 3k miles. On the way back to North Dakota, where I was planning to have this checked, the check engine light came on and went off after about 100 miles. I figured no biggie, since it is a emissions thing (according to the manual).
A couple hundred miles later in the same trip the rear differential blew out and I had it towed to a dealer. After 4 days they had repaired it (I got stuck with a $320 rental car bill).
While it was in I had the 30k manufacturers service done for $982 ( they deducted $8 for the transmission fluid used in the warranty service on the differential)
There was some emmisions service done, that they said *may* help the oil consumption. I have to have the oil checked every 500 mile at the dealer (70 miles away) to see if the oil problem was solved.
The service manager also claimed that the check engine message was erased from memory, by the car(?)
What do you guys make of this?
Is this type of oil consumption cured by and emmisions service?
Did I get ripped off?
Do these vehicles erase check engine codes?
Do I have to make the 140 mile trip to have the dealer pull the dipstick?
Should I think of getting rid of this vehicle?
Your insights would be very valuable to me.
#8132 of 11966 Yakima Rack Question
Jul 12, 2003 (9:47 pm)
Could someone who has installed a Yakima rack w/ Q towers on their Trooper tell me how far apart the bars are if installed according to mfg installation instructions?...is their some flexibility?
I haven't got the rack yet but will shortly and am looking at a carrier that has indentations where it is to sit on the rack bars. Not a problem if one has a factory rack that has moveable bars...could be with an aftermaket rack if the bars have to be placed in a specific spot.
