My check engine came on and the engine is shaking abnormally and idles like it wants to stall but doesn't. When you're looking under the hood you can hear a faint rapid clicking sound which I never hear prior to the problem everything else connections etc. look ok. Fuel injection? Timing? Anyone have any thoughts.

Possible vacuum leak from one of the hoses causing unmetered air to enter the engine. Look under hood in engine compartment and listen for noise to see if it may lead to a disconnected/collapsed hose resulting in a vacuum leak and repair/reconnect as necessary
the engine stalls. (i bet only on a hot engine, , am i right?)
this can be 2 things. but with this huge of engine 1.
the engine idle controls are not idling up.
or extreme, the engine is too weak and the compressor has issues.
does the car driver perfect A/c off? full power and normal hot
engines. and idle speed is at spec hot. near 800 RPM?
(spec, rpm is stated clearly on the hood sticker) open hood look up and under. see that EPA sticker, ?
if RPM is normal. hot.
the engine has huge power.
you turn on A/c and the rpm must not drop
did you try to push the throttle down to prevent the stall.
did that work> yes./no,
if yes,did the A/c belt squeal>?
if that cant work and belt does not scream, the engine has very low power.
the ECU increases idle speed when the A/C is on. this prevents stalls.
this can fail, if the ISC is bad. or diry.
This could be many things from the catalytic converter, to needing a tune up, vacuum hose, fuel pump, injectors or O2 sensors. My advice would be to go to Aamco and get their 89.00 check up. They will diagnose, quote and tell you what is wrong without a commitment on your part. Pretty cheap over all if you are a do it yourselfer and they will gladly fix it for you if you change your mind or just do the parts that you don't want to tackle.
Well this could be caused by a number of things. But the most common cause is an "engine miss." You could have 1 cylinder that has stopped firing. This will cause a very rough idle and very possibly shake or shudder whenever you accelerate. Another cause may be a main "vacuum hose could be disconnected" from it's port. Vacuum leaks cause engine shake at idle. Check for loose, cracked, or disconnected vacuum hoses under the hood. The third and least likely cause is a "broken or worn motor mount". If the engine is not securely held down in place by all the motor mounts, it will vibrate excessively and cause a shake at idle. The engine miss and motor mount problems are 2 issues best left to a professional to tackle. But as I said, you could tackle the vacuum leak issue yourself by checking under the hood. Hope this helps, good luck!
Sounds like a vacuum leak. this will affect the idle causing it to idle high but with no power (at idle) so almost dies at idle in drive, (under resistance) The knocking is likely your exhaust pipe shaking and hitting under car, cos of the engine shake.
Look for a vacuum tube hanging loose from around the intake area. Maybe trim off stretched end and reattach. May be able to hear it with engine running.
I believe you have 2 different problems here. P0410 is the secondary air injection, which only turns on when the engine is cold at first start up for about 20 seconds. All it does is blow extra air into the exhaust to reduce emmisions. There are 3 fuses and items that run this system: Check Valve ($125), Air Pump ($280) and Relay ($50). Prices came from Napa, so I'm possitive you'll find any of these much cheaper elsewhere. My guess is the relay since you have dimming.
Did you recently have the battery disconnected? Trying to address the stalling while at idle. If so, it's your throttle body, needs to be cleaned. If you want instructions on how to do this yourself, let me know, will only cost you about $4. I know the dealer charges about $85 to clean this where I live, which is outrageous! If you do have a shop do the work, make them remove the throttle body to clean it, don't just clean the outside of it.
Even if you don't do this work yourself, at least you know the lingo and shouldn't be surprised.
there could be a couple of things causing the engine to stall, most common would be a large vacuum leak, check all vacuum hoses under the hood paying close Attn. to the large hose going to the power brake booster,but the most common thing to cause a idle stall is a idle control motor some times it is called an idle air motor.
The shaking can be caused by a bad motor mount, but could also be caused from the engine when it is idle'ing low and about to stall. The motor mount would also shake the car under braking, so if is doesn't shake whiIe your braking it's probably not motor mount, Is your check engine light? The idle air is another possibilty among other things. I can assist further but I need to know which engine you have the 4 cyl 2.0L or 6.0 cyl 2.5L?
