Why does my truck pop when idling?
Why does my truck pop when idling?
Now if the car sounds like a real slight miss or pop at idle, it could be a burnt exhaust valve or an exhaust valve not fully seating and seal properly. It could be spotted in a compression or leak down test. The “burbles” or “popping sounds from the exhaust” as you have crassly put, are a result of exhaust back fires.
What does it mean when my engine pops?
When an engine is running rich, it has too much fuel and too little air, which slows down the combustion process. When combustion doesn’t happen in a timely manner, the exhaust valve opens while the air-fuel mixture is still igniting, causing this explosion to “spill” out of the cylinder, making a loud popping noise.
Why does my car make a popping sound when I start it up?
The Fix: Check firing order and place wires on the correct spark plugs. The Symptom: Engine hesitates, and a popping sound comes from the engine. When you step on the gas, the engine bogs down or takes a second to respond. You may notice a general lack of power. The problem may occur when the engine is hot or cold or when you are low on fuel.
What causes an engine to stall in cold weather?
Engine stalling problems can be hard to find and are often sensor or temperature related. Engine stalling is more likely to occur during cold weather or when starting a cold engine. So, this kind of engine stalling problem often means the engine is not getting enough fuel and/or too much air.
Why is my car engine so loud when I step on the gas?
When you step on the gas the engine pops, spits, and backfires. Sometimes it’s loud, sometimes it’s not so loud. This can cause severe engine damage and/or fire under the hood. Possible Cause: Camshaft timing belt or chain has slipped.
What causes a car to stall with too much air?
This throws off the expected air fuel ratio and causes the vehicle to run lean. If you have a bad vacuum leak, the air fuel ratio will end up being way too lean (too much air) which could cause the vehicle to stall.

Why does my truck make a thumping noise at idle?
A miss on this engine is clear at idle via a bad shake. These engines do make this noise warming up sometimes. That’s the video of it running. Wasn’t quite as loud as it normally was but you can hear it near the air box.
