They are welded in to the exhaust stream so as to prevent easy removal, its a government thing for the protection of our air quality.
yes new ones 2011-2014 has a DPF Diesel Particulate Filter and a Catalytical converter
A flashing check engine light means that you have a problem with your engine that may cause harm to the catalytic converter.
dont do it. on my 2001 it sounds obnoxious and it will not run right due to isuzu's over-engineering on these vehicles.
Could be as simple as a dirty, plugged up fuel filter or as bad as a damaged catalytic converter. If there is a check engine light illuminated, start with having the codes scanned.
Look under the Trooper and count them.
I'm not a mechanic, but I'm pretty sure you have one O2 sensor just before the catalytic converter and one after. The first checks the function of, and regulates, your fuel control unit, and the second checks the efficiency of your catalytic converter. My #1 O2 sensor is screwed into the exhaust pipe about a foot or two before the converter and kind of looks like a spark plug. On a 2003 Isuzu the O2 sensor is on the driver side of the engine compartment about a foot down from where the exhaust pipe comes out of the header. Just follow the exhaust pipe out of the engine and you will see it. It looks like a spark plug sticking out. It's pretty easy to disconnect the wires, unscrew it and replace it. You will need a 7/8" open end wrench to unscrew it. Good luck. * 1999 Oldsmobile Aurora's actually have 4 O2 sensors, 1 on each header and 1 before, and 1 after the catalytic converter...
Don't know about cat conv, but my EGR Valve just failed, I'm told a common problem on 3.5L 'Honda' engines; my light will be on until I can afford to replace the valve.
The fuel filter is located near the right rear wheel bolted to the chasis.
It has four (4). Two located before the catalytic converter and two after it. Edit: This depends if you have an OBD-I model or OBD_II model. Since all cars after mid '96 are OBD-II then if you have a V4, yes it has four (4). But if you have a V6 engine it only has three (3): a preconverter sensor in each exhaust manifold and a post-converter sensor.
Starter is on passenger side of motor underneath intake bolted to trans bellhousing.
Go outside and look under the vehicle and count them.
I own A 1995 Isuzu Trooper 8 cyl. I have been having the same problem and with much research and what-not i have found out the Oxygen sensor needs to be replaced, as well, because i have waited so long to replace it, the Catalytic converter now needs to be replaced. I hope that your car has not gotten to this point because the cost to replace the catalytic converter is $700+. the cost to replace the O2 sensor is $270+. The cost to replace the sensor yourself is 40 dollars and the cost of the converter itself is 80 dollars. I know the sensor is fairly easy to replace but i have no idea about the converter. I hope that helps.
