Engine light stays on and loud idle noise same as at home before trip. Had mechanic look at it on trip. He said he saw no
problems. Said I need to install padding under hood. Its white with front guard and rear tire.
#118 of 137 Fuel guage problem
May 14, 2011 (12:38 am)
My fuel guage all of a sudden one day started reading Empty. All forums and mechanics said it was the fuel pump and/or the sending unit. I replaced both...problem persisted. Replaced the sending unit one more time..same indications...mechanic said it was the computer, so I replaced it...problem persited.
A different mechanic said it was the fuel guage. I replaced the entire cluster...problem still persists.
Guage read empty.....Replaced, fuel pump, replaced fuel pump sending unit(twice), replaced vehicles computer, replaced entire guage cluster.
The guage still reads empty..never wavers..like it is NOT geting any power.
This is driving me crazy, and I have to drive from Orlando to Colorado Springs next month.
Please..any ideas at all . Thanks
#119 of 137 Intermittent Check Engine Light
Jun 06, 2011 (4:19 am)
I have an 02 LS and the check engine light is going on and off on an intermittent basis. I have had it on several computer diagnostics with no codes emerging and the vehicle had no problems going through emissions...passed easily. I've checked and re-checked the gas cap and have no problems there.
The light will come on at start-up for about 3 days and then not come on when I drive the next time. It never comes on or goes off while vehicle is in motion.

I have an isuzu rodeo 2000 3.2 v6 that I bought early last year and I haven't stopped spending money on it since I bought it. My check engine light has been on for almost the entire time I've had it and the mechanics say its the wire harness BUT it could also be something else and they wouldn't know until they replaced the wire harness. I've spent so much money on this car it's ridiculous.
My friend is a mechanic and has re-wired some of the harness and we thought he'd fixed it but now the light has come back on. I even have a friend who has the same car and he has problems with his too! I actually hate the car.
We're going to host a destruction derby with our isuzus and people can pay a small fee to watch. At least I'll get something back from it.

One of the most common problems I've found during my research is that an intermittent light is/can be caused by a Gas Cap not giving a good enough seal, might be a good idea to replace it.
Also, the vent line clogging up cn cause an intermittent light.
I just had mine blown out, and it solved my inermittent light problem.
#122 of 137 Check Engine Light on Isuzu Rodeo 2000
Jun 13, 2011 (9:47 am)
I have a 2000 Isuzu Rodeo LS 4WD. It all started with a persistent Check Engine Light. Took it to a local auto repair shop. Was getting a 'System Too Lean, Bank 2' error code. Then the mechanic changed oil filter, checked the fuel injector and replaced it on one cylinder and replaced the spark plugs and checked the coils by switching them around on different cylinders. He also mentioned that there is low pressure in one cylinder (around 75+ instead of 125 on other cylinders). After he finished tuning the engine, now I get the same check engine light but getting the 'System too lean/heavy' codes as well as 'random cylinder misfire' p0300 codes also.
He says probably something is wrong with that one cylinder it might involve a full overhaul of the engine.
Can somebody provide some expert advice on what the next steps should be for me?. Looking for second opinion.

This is the craziest thing, but I have a 1996 Isuzu that the "check engine" light just came on in. And as it turns out, I just drove from Orlando to Colorado Springs in April. The coincidence was pretty weird. Hope your drive goes smoothly!

There is a tube from where the egr valve is on the side of the engine to the front of the intake manifold, this usually gets plugged. You can see the end of the tube if you remove the intake hose from the throttle body and open the throttle body by hand. The tube is about 3/8 inch in diameter just behind the throttle body. You will only see a pin hole in end of the tube if any opening at all. It can be cleaned with tubing brushes from a Harbour Freight 10 pack of brass / SS brushes, SKU 95947. Normally you will need to remove the throttle body from the intake manifold. The end of the tube is usually pretty hard and you will need to use the end of a piece of wire like a wire cloths hanger to get the hole started before you can get a brush into the tube. Start with a small brush and work your way up, just pushing the brush in a little at a time and pulling it back out. If you have access to an air compressor remove the egr valve or remove the hex plug under the egr valve and blow the line clear after cleaning. Don't loose the hex plug, it is aluminum. Don't damage the gaskets and you should be able to reuse the gaskets. The EGR valves on these vehicles seldom go out, it is usually this tube.

Check your fuel pressure regulator, located on the back of the engine, drivers side. See if it has fuel coming out of the vacuum line when starting the engine and the engine is cold.
