Hi, it would help to know how many miles and what type of transmission is in your vehicle. The symptoms you describe could be attributed to poor gasoline, failing timing belt/pusher and possibly a bad steering pump or alternator, so any information like service to trans, parts replaced, etc; will help generate interest in helping diagnose the problem.

I was laughing hard reading your post especially the "dragging" part
I think that, realistically, only H2s, Monteros, and older Kia Sorentos can edge the Trooper (though very slightly) in how much gas they use.

I have a 2000 Trooper LS. My gas mileage averages from a low of 16.5 to as high as 18.5. Not bad for a large, heavy box. The numbers have run about the same over 130,000 miles. Mine is 2wd and it seems that 4wd or TOD versions might get about 1 MPG less on average.
Have you had the brakes checked? If you have a bad caliper that is dragging, that could really hurt the mileage. Have spark plugs ever been changed? They are good for 100K miles max. Also probably need to check that they are the correct ones. Reports of changing to non-specified plugs can cause problems. You might also try some fuel system cleaner, either have it done or run several batches of injector cleaner through.
Is your Trooper displaying a CEL? If so, code from that might point to a problem.

#11723 of 11965 Head gasket-Oil mixed with coolant
Apr 14, 2008 (7:40 am)
I have a 90 Isuzu trooper. My oil is mixed with coolant. Before this and now my car is going through tons of coolant. I'm pretty sure it's the head gasket. First has any one used the liquid sealer? I thought of trying this first to get me by till I can get a new head gasket or better yet a new engine. Is it ok to drive it till I get this done? I just bought the car a month and half ago and unfortunately the seller didn't tell me about this problem.

Forget liquid sealer,Afraid to say your head gasket is shot,Looks like you need to strip the head off and get it skimmed then fit a new gasket set,also to be honest i would not drive it as dont forget the coolant is also going into the sump,oil floats on water so you could end up with a sump full of water and the crank shaft bearings would not like that and could sease the engine,Sorry to be the bearer of bad news,Regards,GERRY

X 2 on the advice from egyptgerry. Don't continue to drive it. The antifreeze will dilute the oil and your bearings and rockers will be shot. Plus you don't know what the engine has been through before you owned it. It is a pretty common problem on the 2.4 and 2.6 motors. There are aftermarket heads (AMC and others) available that are made heavier and pretty much eliminate warpage and fracturing common in the Isuzu head. HTH.

Glad 2 brains are better than 1,But really the 2.4 and the 2.6 where not the strongest of motors,I used to have them for my business but changed over a few years ago now to the 3.1 td but i do have a 3.0 v6 that runs on LPG gas,gives no problem and the co2 emissions are so low it passes our annual test here with flying colors
#11727 of 11965 1999 Trooper water pump question
Apr 16, 2008 (1:25 pm)
On my '99 Trooper 3.2L I have removed about all that is needed, but can't figure out how the heck to get the plastic plate with the timing marks off to get at the water pump. Looks like I need to remove the pully, which is bolted to the crankshaft. if so, how do I stop it from spinning?
Any tips will be appreciated.
