Where is thermostat?
Follow the big hose from the top of your radiator to where it is attached to a metal elbow that is bolted to your block. Should be three little bolts. Remove those, and there is your thermostat. If the information is helpful to you please give me your ratings. Thanks

Check for clogged air filter, an obstruction or leak in the duct that joins the turbo unit outlet to the intake manifold.An intake manifold gasket leak, a leak or obstruction in the exhaust system or a waste-gate problem.
The vacuum line is either blocked or there is vacuum leak .Also get the fuel pump and spark plugs checked.------
---Also other possibility is compressor surge.The turbo is spooling up too fast and sending too much air into the engine for it to take. You can fix it with a larger A/R exhaust housing. You can also fix it with a surge-ported compressor housing.It is not your blow off valve. But the valve will often open when you get compressor surge since it sends very high boost spikes into the inter-cooler pipes.Compressor surge can damage the turbo bearings, Get it checked.----------

RATTLING>CAR DIED>TIMING CHAIN?
Usually when rattling only occurs at 0 mph, that rattle comes from a metal component (often in the engine bay) leaning against a part of the vehicle frame. The air filter housing or retaing screw/nut/bolt/clip(s) could be to blame, so make sure that it has been properly secured so that it does not vibrate against the hood, an engine mount or the frame of the vehicle. However, it could be caused by the transmission or an engine component, such as a thrown piston rod. You did not mention any work that was done recently, so I'll just have to exclude relevant possibilities (such as a tool left under the hood). Timing components can definitely cause erratic & severely affected engine performance. Try not to drive this vehicle any more than absolutely necessary. Until you know what the issue is, prepare for the worst-case scenario.
Touchy throttle response could be from pressing on the accelerator when the transmission is out of gear (sometimes transmission anomalies such as low fluid level can result in slower transmission response—possibly allowing the engine to rev without affecting vehicle speed). Then again it could be a faulty throttle position sensor.
Square away the basics: Take the vehicle to a full-service shop for inspection. AAA members have affiliated places that would inspect a vehicle for travel-worthiness. They would check the belts & various other areas & conditions such as coolant, oil, & transmission fluid levels. You need a professional, qualified mechanic to pinpoint this with a physical inspection. If you're not a member of AAA, you can still go to many of the same places. (General rule of thumb: A $25 inspection that leads to a $250 repair still beats a $2,500 engine or transmission replacement from neglecting what could have been fixed.) Note if there are any warning lights showing on the dashboard when driving this vehicle. Tell the mechanic ALL about it! Unexpressed issues are usually the cause of unsatisfactory results. When you need guidance on the inspection's findings, we'll be here. A professional inspection is the best way to handle this scenario.
