2001 Isuzu Trooper cuts out and dies while driving diagnostics not helpful. by willielt

2001 Isuzu Trooper Limited cuts out and all gauge lights come on as it starts to die. If we keep giving it gas it will keep running sometimes. When it dies completely while driving we can restart in Neutral. We had Firestone do a diagnostic on it, they had it on the rack for 1 ½ days and said they checked everything and could not find the problem so it must be the Computer and that we should take it to an Isuzu dealer to heck and fix the Computer problem. The Isuzu dealer in St. Peters, MO. Said that they tested the Computer and found no problems. They said that the problem was carbon build up and that we needed a carbon clean out. After having the carbon clean out the problem remains. The problem started out once a week 3 weeks ago and progresses to 4 or 5 times daily a week later that’s when we took it to Firestone. Ten (10) days ago Isuzu did the carbon clean out and now the problem has continued to get worse, it happens every 6 to 15 minutes. We moved from St. Peters, MO, to Ames, Iowa a week ago after getting the car back from Isuzu. This was a very stressful move because of this problem. I have some automotive knowledge and amy not afraid to get my hands dirty. This is getting expensive. Please help us if you can. Thanks and have a great day.

2001 Isuzu Trooper Using/burning oil by lljackson

Hi
My daughter's 2001 Isuzu Trooper with 89K miles is using oil real bad. I had the oil changed and about 1000 miles later I noticed that there was no oil on the dip stick. There are no visible signs of an oil leak. Does anyone have any suggestions other than checking the oil weekly or bi-weekly and toping it off ? I would appreciate your help !

It sounds like the same problem i had with my 2000, intake manifold gasket. The gasket was a defect when built and the new one you put in will prevent it from happening again.

They all burn oil, i have a 2000 with 93000 that has burned oil since new. You MUST check oil weekly, if not bi weekly. Also, use 20/50, NOT 10 W 30!!! If in warmer climate,use 30 wgt detergent oil. Im in florida and use 40 wgt in summer, slows oil burning in half.

I'm new here. We are on our third Trooper. Love 'em. It's a 1999. 238k miles. The CEL indicates a vacuum leak but our mechanic and an import mechanic have not been able to locate it. We've done the EGR, MAP (MAF?) sensor, new gas cap, fuel filter. The car stalls and dies when the RPMs drop such as descending a hill, making a turn or coming to a stop. It is random. Some days good, some days bad. I'm beginning to think it's the intake manifold gasket from reading threads here. Would that show up as a vacuum leak and would it be intermittent?

We did replace the gasket and had the tube to the EGR cleaned. No more stalling problems. Cost was $257. However, CEL came back on after two weeks. Then went off. Then came back on. Code reader used to say vacuum leak now it is a vapor leak. Whatever. At least it doesn't die now!

Trooper cutting out and intake manifold gasket??? by htfeaster

In reading the posts, this sounds quite familiar to what happened to me. I recently purchased a trooper from a friend who takes impecable care of his vehicle. I had some performance issues and thought it might be my battery and changed the battery and cables. A week later I was driving my trooper when it stopped and all of the computer lights came on. I know very little about cars and had it towed to the nearest repair shop where they told me I had only about one-quarter of the oil needed (and i had a recent oil change with no signs of leaking) and I need a new engine or motor to the tune of $5000.
 
After reading these posts I am wondering if the problem is the intake manifold gasket? Any suggestions? Should I ask them about the intake manifold gasket, take it somewhere else, etc. I hate to immediately be so suspicious but there were never any signs of a problem of this proportion and the repair shop is quite aware of my ignorance reagrding cars. Is it possible the engine or motor may need to be completely replaced? Any ideas, help or suggestions would be greatly appreciated!
