2005 chrysler town and country when i start the van it shaking vibration hard in park and in reverse it and in neutral and in drive it perfect.it drives good on highways no shaking


try to increase the idle-rpm..
Example - at standstil condition when you start your van, have look at rpm... say 1000 or 1200 or 1500.. whatever it may be..
Keep idle-rpm a little bit higher, if previously it was 1200rpm then set it to 1500 rpm..
If the problem is solved then..
1) clean ur airfilter
2) check spark plug condition
good or bad... if bad then replace..
3) check fuel supply line, if it is damaged or folded

2001 chevy suburban. I hear a humming noise from the engine. Engine ticks while idle for after a few minutes. Ticking goes away when I accelerate. There is a strong vibration when I accelerate in drive but...


Ticking sounds like a dry lifter, when was the last time you changed the oil and filter? Humming sounds like you need a tire rotation because of uneven tire wear.

Is your engine an automatic? If yes - The engine diagnostic should pin point the problem. Which could either be the air flow sensor, idle sensor or the throttle sensor needs replacing.

I'm wanting to know the longevity of a Chevy 5.7L


If you are only at 184,000 miles, it all depends on how much and how you drive this van. If you keep up on your routine maintance, drive it respectively, you should get well over 300,000 miles total from this engine.
Each person drives differently, so if you are the only driver and it's only driven to and from work + minor local driving (shopping etc.) this engine should last you as long as you own the vehicle. For a 98, 184,000 isn't bad - have seen less because owners are that particular about how often and how far they drive the vehicle, some of which have a secondary that they use for their more frequent traveling. It all depends on what you use this vehicle for.
I hope this information is helpful.

My 1993 chevy k1500 v8 350 5.7l idles up and down and somtimes when im driving the check engine light comes on and it runs poorly why.


You'll need to find out what code you have. There are lots of differant things that can cause a check engine light or a truck to run poorly.
For what it's worth sounds like a vaccume leak, maybe the egr. But you need to find out what the code if first!

Chevy 350 express van 2000 runs great idles rough


If it does not do it in park or neutral, it could be a number of things. One being a sticking Torque Converter Clutch solenoid (TCC). It could be that it needs a simple tune-up. How often does this problem happen?
