SOURCE: Getting DTC code P0404 and P0420. What should I do?

The 420 will not go away with egr replacement. it means the computer has detected a problem with the catalytic converter. eGR valve is at the rear of the engine. Not easy to get to on vans.

SOURCE: 2008 jeep wrangler how to reset service light

there are two ways to reset the light. you can use an obd2 scan tool to read and reset it or you can pull your battery cables off for a half hour and that will also reset it. just be forewarned if you have not fixed the problem that turned it on in the first place it will just come back on. if you have fixed the problem after 50 starts without seeing the issue again it will also clear itself.

I got a jeep wrangler unlimited 2008, glow plug indicator light shows up when the engine is cold but after it has run for sometimes and the engine

Sounds like a diesel. Glow plugs usually need to be warmed up before starting an engine. Smaller diesels either warm up quicker or it is less critical than a tractor trailer. So either your glow plug light is normal letting you know it needs time to warm up or it's letting you know they are weak and need to be replaced. I'd check the owners manual to be sure.

2008 jeep wrangler hood problem

I just bought a 2008 jeep wrangler and my hood is lifting 2 to 3 inches off the frame when I'm driving on the highway in wind speeds over 15 to 20 mph. I've owned two jeep wranglers in the past and I've never had this problem but chrysler keeps telling me this is normal. What's normal about a hood that is lifting off the frame?

How to reset the abs warning light?

Some scan tools can do it. In my experience if you fix the problem with the brakes the warning light will go out by itself. With the ABS light on, typically you have no anti-lock brakes.

Car code p0404

its under warantty the 8 year smog.
this is EGR failure.
and is NOX smog rules. and is in warranty.
all cars .
for 8 years.80k or 15/150k, depend on car.
but whichever first occurs
so if over 80k do say so.
the EGR can fail for many reasons.
carbon blockage ro the $100 valve is bad.
remove valve and clean it.
reset OBD2 and run car, if comes back
the EGR path must be cleaned.

Engine shuts off for a few seconds and restarts all idiot lights come on

You may want to check with factory recalls. There was a letter sent to 2007 owners about a computer upgrade to solve loss of sudden power along with some ABS issues.

Rough idle, stalling

You must get the system scanned for fault codes, sounds like the electronic throttle control has a failure.
