What Causes the Delayed Ignition with Abnormal Noise in Camry?

Here are the specific reasons for delayed ignition with abnormal noise in Camry: 1. Carbon deposits or component contamination: Throttle carbon buildup can affect the perception of throttle and air intake, causing delayed or incorrect signals from the computer, which may prevent the vehicle from starting; the fuel injector is prone to accumulating sticky substances that can block normal fuel injection, leading to poor gasoline atomization, thus causing delayed ignition and difficulty in starting the vehicle. 2. Inappropriate oil viscosity: For example, in very low temperatures, high oil viscosity can slow down oil circulation, causing mechanical dry friction, making it difficult to start the car and resulting in delayed ignition with abnormal noise.

I've been driving a Camry for several years and encountered issues with delayed ignition accompanied by strange noises. Typically, you should start by checking the battery, as insufficient power can make the ignition sluggish, causing the starter to emit a harsh clicking sound. Worn or stuck starter motor gears are more common causes of delayed starts with odd noises—that was the issue with my car last time. If the spark plugs haven't been replaced for too long, their efficiency drops, leading to slow ignition. Don’t overlook the belt system; if it’s too loose or worn out, it’ll squeal during startup. Lastly, fuel pump pressure issues can also cause prolonged ignition delays. After discovering the problem, I immediately took it to a professional repair shop for diagnostics. Replacing some parts fixed it, and I strongly advise not to delay repairs to avoid getting stranded on the road.

When I first got my Camry, I always felt a slight delay and strange noises during ignition. After some research, I learned that the most common causes are an aging battery with low voltage making startup difficult, or issues with the starter motor gears causing noise. Worn-out spark plugs can also affect ignition timing, slowing down the response. Belt tension is crucial—if it slips during startup, it produces abnormal sounds. Insufficient fuel system pressure can similarly lead to ignition delays. I tried checking the belt for cracks or wear, but ultimately, a professional diagnosis is needed. It's best to address these issues early to avoid compromising driving safety.

My Camry has been experiencing delayed ignition and strange noises, which is quite bothersome. Common causes include a faulty starter motor or low battery power, and old spark plugs can also lead to slow ignition. The strange noises mostly come from the belt system, such as slipping sounds from a loose tensioner or fan belt. Ignoring these issues may lead to bigger problems. During regular maintenance, I ask the mechanic to check these parts to ensure the battery is functioning properly and the spark plugs are clean. Safety comes first, so any issues found should be repaired immediately.
