#1385 of 2303 1997 RODEO by bgolemo

Jun 05, 2004 (2:45 pm)

I own an 1997 ISUZU 3.2L and I am really disappointed with the miles per gallon. In the city I am getting about 12 MPG and on the highway about 15 MPG. Can anyone help me out with their thoughts? It runs really smooth and is well maintained. I do not have 4-wheel drive, winter, or power modes engaged. Any one having similier problems and if so what have you found out?
 
Thanks A LOT

Do you have a roof rack or any mods? each mod could cut 1 MPG off per change, making a 15/19 vehicle run 12/15. I have a 1999 Trooper with very similar mileage. If I drive it easy I get 11-12 around town. Just plain blows. I had the EGR and PCV valve cleaned, am careful about maintence, fuel injector cleaners, etc. I have added tires, roof rack and bull bar, so I assume those changes are keeping me in the cellar. Some people have changed spark plugs with moderate success.

i just got a 99 isuzu,and it gets about 12mpg...it's pathetic. If i'm driving and let off the gas it does not coast, it starts to slow down immediately as if there is something slowing it down. does anyone else have this feeling or problem when they are driving. maybe there is something going on with the transmission, i dont't know. if anyone has any recomendations i would appreciate it. i don't have any mods or roof rack

I am not sure what trans the Rodeo has, but the GM transmission in the trooper has a "feature" where it doesn't shift-up at the same speed points until the fluid has reached a specific internal temperature. I have a very short commute so the first 1/3 of the way I have the same issue.
 
If this is all the time, then perhaps there is a problem with the truck going into overdrive or your highest gear? If I keep my truck in "3" as opposed to "D" I experience the same thing too. Maybe there is a shifting problem? Can you count the upshifts and verify that you are getting to the highest gear?

I have been having the same problem with my 03. I went to the pump yesterday and filled up, as I was below E. I filled all the way up, and only put in 15.2 gallons. The tank holds 19.5, which tells me that the sending unit is bad. Called the dealer and she said the sending units were notorius for going bad. That could be your problem. Once I get it checked I will let you know.

On these trucks is heavily effected by your speed. Under 65mph on the highway you can get the MPG that is advertised, in city with a light foot you are fine. Start hammering the gas a bit to get these rather heavy TRUCKs moving, and you'll drop your MPG quickly. In the same respect over 65mph and you'll see a nose dive in MPG. Remember the ratings are taken on a dyno with no wind resistance at 55mph.

#1391 of 2303 Isuzu Rodeo VS Jeep Cherokee by jdudley

Jun 10, 2004 (11:28 am)

ADVICE NEEDED:
I have an opportunity to sell my '95 Isuzu Rodeo for the same price my friend will sell me his '96 Jeep Cherokee. Should I do it? (details below)
'95 Isuzu Rodeo: 89k miles, in good condition, will need new tires soon, several minor things wrong.
'96 Jeep Grand Cherokee: 130k miles, in mint condition, no problems.
 
You see my dilemma. The Jeep has many more miles (all highway), but is in much better shape than the Rodeo. Which one would you keep?
Thanks,
Jim

#1392 of 2303 CE light and gas gauge by Boris2

Jun 14, 2004 (4:16 pm)

garodeo, I noticed the same thing with my fuel gauge showing below empty and I can only squese 15.5 gal (I think the tank is around 18 gal or so). Did you take it to get fixed? Does it need to be fixed?
 
One more problem that I wanted to ask everybody is that starting about a month ago the CE light would go off when I fall below empty on the gauge. I know I have plenty of gas in the tank as, as I already mentioned, I can fit only about 15.5 gal. So, lack of gas shouldn't be the problem. The light goes away after I fill up and drive for about 30 min to an hour or so. Since it's not the first time i fall below empty, that kinda bothers me. The truck has 54K mi and I think it first started at about 51-52K mi (right after the end of manufacturer's warranty, of course). My only guess is that over the period of 3 years (it's '01), there's been a decent amount of water and other stuff accumulated on the bottom of the tank. However, with about 3 gal left it doesn't seem reasonable.
 
Anybody had the same problems or heard of anything like that?

I've never been able to squeeze more than 16gal in my 2002 LS 4x4, even when it's below empty w/ the low fuel light on steady. Gauge needle has always tracked normally. Only have 25K miles on it though. Isuzu says it's a 19gal tank. From what you describe, your fuel gauge seems to be tracking normally, so the CEL is probably not fuel sending unit related. It may be an EVAP system code. Have to read the code to find out for sure.

Try buying a new gas cap. That clicking you hear when you turn it is like a spring loaded pressure vent. Perhaps it isn't regulating the pressure correctly when you are low on fuel. If it goes away on fill-up, it sounds like a gas cap issue.
