#60 of 93 99 izusu rodeo spark plugs fouling out gas in spark plugs by hill999 Jun 23, 2008 (12:37 pm)
I have a 99 izusu rodeo. I seem to be getting a lot of gas in spark plugs. They foul out at about 500 miles. When I go out to crank it, it takes about 4 or 5 cranks and when it does crank its shaking like a dog scratching fleas. After I let it idle for a min or 2. then I have no problems. Gas gage doesn't work and check engine light goes off and on. Mostly on. No oil lecks But I have to add About half a pint of oil between oil changes. My fan runs even after I ve cut the car off and I have no air. The main problem is the spark plugs. And shaking. Not wanting to stay crunk. anyone can help thats.

Replying to: tjsnow (Jun 12, 2008 11:21 am) dealer wanted to change whole engine wiring harness $1200 (with diag) on my 2000 rodeo, took to another mechanic who found 3 shorts in wires, replaced the wire and it cost $250. I did recently take it back because it intermittently has a rough transition from 2nd to 3rd gear which I am thinking is another short.   Don't know about the gas in spark plugs issue, but good luck all
#62 of 93 Isuzu fuel sensor by laffnfun1 Jul 09, 2008 (8:58 pm)
I have not been able to smog my 2001 Isuzu because the check engine light is on. My problem sounds identical to others I have read about in that the fuel sensor indicates either low or no fuel which is not the case. If I have a private mechanic fix the problem ( so far estimates range between 650 and 800), will I have to go to a dealership to reset the computer? There is no local dealership so this would end up being inconvenient as well as costly. Thanks for any insight.

That problem with the cruise control light and check engine light came back and when I took it to my mechanic he found a couple of wires that were exposed (Stripped) to the metal of the car and engine and were causing shorts when I'd hit a bump in the road . He taped up the exposed wires and I haven't had the problem ever since. These trucks are great but my God do they give a crap load of problems when they decide to go bad. After that problem, my A/C compressor went and now I have a check engine light on for the Evap Solenoid .......Any one know if this is a hard fix?
#64 of 93 Check Engine Light on 1996 Isuzu Rodeo by dsirek Sep 24, 2008 (4:47 pm)
Scanner says two front 02 sensors, not registering, replaced all four sensors, get same error code. Checked sensor signal wire reading says 3 volts but should be .09 volt max. Ruled out wiring harness because there is continuity from signal wires to computer. Can anyone help.

I was trying to change the spark plugs and wires on my wife's 1998 Rodeo. When I pulled the plug boot, there was oil on it. It was on the other three boots as well. I have a misfire in cylinder 2. I put a new set of wires on but, the idle is still rough and it doesn't accelerate like all 4 cylinders are firing. Why is there oil in on the boots? Should I wait until I figure out the oil situation before putting in new plugs?
#66 of 93 2002 Isuzu Rodeo LSE 3.2L Check Engine Light by gman39 Nov 23, 2008 (5:13 pm)
Good evening all,   I also have the check engine light on. I had it looked into, and I was told that it is due to a bad Oxygen Sensor. It's not going to cause the car to break down, but it is slightly damaging my gas mileage, and causing that check engine light to stay on.   Does anyone know if it is possible to clean the inside of the fog lights? I have some rusting due to water intrusion. I am getting ready to replace both lamps via a new assembly kit, but I am trying to avoid spending $150.   Thanks.

Replying to: bucsngoofy (Aug 17, 2006 8:16 pm) I had that problem too and the issue was a loose wire connecting the engine control modude to the crankshaft sensor switch. The engine control module does not sense where the crankshaft position is when the wire moves, and that causes things to go snaky, such as the transmission and cruise lights coming on. This issue took a good mechanic in Syracuse one and a half weeks to find. Total cost was $425.00,$395.00 for labour, and $.99 for the new wire. Good luck!

Replying to: princessnaeya (Oct 16, 2005 6:41 pm) my check engine light has come on since about 4,000 miles. I find that when I fill up the tank it goes off or shortly after that. It seems to have a mind of its own.
#69 of 93 2000 Rodeo Lost MPG Suddenly by justagirl7 Jul 05, 2009 (3:06 pm)
my 2000 Rodeo has suddenly lost from about 20 plus around town, down to about 12 mpg . I only have 37,000 miles, original owner... no computer codes have been found. It started in March...
