Question about Dodge Caravan

1 Answer

Had a bad egr valve and replaced it. Engine seems to bog down terrible. Parts guy says he thinks it is act converter clogging and to tap on it. If it sounds hollow it is ok. Drove the vehicle about 15 miles and EGR valve melted in same spot. Why is EVR valve getting so much heat???

    I was told to tap on the converter and if it sounded hollow it should be ok. I don't know if this is a correct way to check it or not.

You have a plugged exhaust, replace the catylictic converter and find out what make it fail and plug, rich fuel mixture is most common cause of overheated burnt cat. The EGR is just a symtom of the plugged exhaust.

    No, that is not the way to check, to be sure you need to run an exhaust back pressure test, (a muffler shop can help you as well), a shop has to do this, it requires a few special tools, but I am sure that is the problem by what you said about the EGR being burnt, the pressure in the exhaust causes that. Do you understand? If not call 925-459-0571

I am working on a 2000 suzuki esteem 4 door with a 1.8 litter to car bogs down as if it has now power even when its in park or neutral you can't get more then 2000 rpms on it and it bogs down

Probably a clogged catalytic convertet. One sure way to test that theory is to unhook the exhaust pipe from the catalytic converter and try then. It will be loud but if the converter was clogged you will have your power back. Replace converter if you have power after the test.

I have a 98 lincoln navigator I got the egg valve replaced and my check engine light came back on with the code p0401 what should I do next to fix the problem

TYPE: OBD PO401 & study the code

I think your best to have a professional use
the proper testing tools, to actually find a problem

You can throw parts at it for a long time, if you do not
understand the system your working on, or have no factory
service manuals or trouble charts to follow

I see you said you got a part replaced

So the shop failed to road test or look at data to confirm
the repair,too bad,that seems to be the problem the last 25 years

2001 toyota sienna, 6cyl 3l, must accelerate very slowly from stop or van seems to bog down badly, may take 2 miles to get to 55 mph, going up bridges it bogs down very badly, diagnostics indicated...

Brake loose connection between cat and exhaust manifold , it will allow exhaust gas to go out before cat , and see if it's restore the power on the engine.
If it does then your cat is clogged.
If not it's also might be Throttle Position Sensor , or Mass Air Flow Sensor.
You can't remove cat , you have to replace it if it's bad. Cat is a part of Emission control system.

1996 buick century, I had a tune up and egr valve

Have an auto parts store check for the code. It is possible that you have a bad O2 sensor or your catalytic converter is clogged.

I have a 1997 jimmy and it cranks up fine but it starts bogging down when i am driving and when i try to climb a hill

You may have a clogged up egr valve. When the egr valve gets clogged up with carbon, the truck will run rough, surge stall, and be very anemic on power. Is the service engine soon(check engine) light on? I've dealt with this issue before, and those 4.3 v6's tend to get egr issues. Try this: when it bogs and runs rough, stop truck, open hood, and tap on egr valve base( where it bolts to engine) if rough running clears up, there's your problem. Egr valve is located on front of engine just to the rt of alternator bracket.

Sounds like the catalytic converter plugged. Don't continue to drive car till something gets done with this as you can damage the engine by the excessive heat. Do something but remember it is illegal to take these converters off and not replace them, so be careful what you decide to do. good luck with it.

Turned car off at gas station want start back acts like missin

all of these problem codes refer to EGR valve and emission controls. It may be, if egr was fixed, it would be ok!! take off EGR valve and clean carbon from egr hole in engine and from EGR valve. if egr valve is bad or plugged with carbon then the car will act like it is not getting fuel, it will bog down.
