Why does my Honda engine hesitate when I accelerate?
While you are most likely to notice engine hesitation when you’re accelerating, engine surging can occur intermittently. Figure 3. Reduced engine power can be attributed to a clogged fuel filter or faulty spark plug wires.
What causes bad fuel economy in a Honda?
Poor fuel economy can be exacerbated by a loose gas cap, clogged fuel filters and fuel lines, or clogged injectors. Check for trouble codes in your car to diagnose a faulty fuel system.
Why is my Honda engine not producing a spark?
Corrosion at the spark plug terminals may cause them to not produce a spark, or cause the engine to misfire. In addition, any faults in the ignition coil or distributor may cause the same issues. Follow these steps to diagnose your engine’s spark:
What to do if your Honda engine wont start?
In addition, any faults in the ignition coil or distributor may cause the same issues. Follow these steps to diagnose your engine’s spark: Pull the electrical feeds to the injectors. Obtain an extra spark plug, and gap it properly. Pull one of your spark wires from the spark plug end. Use a deep socket and ratchet to remove the spark plug.
What should I do if my Honda engine is hesitating?
Let the engine cool. Remove the hose between the air box and the front of the throttle body. Apply a small amount of brake/carburetor cleaner to a rag, and remove the grease, dirt, or oil from around the intake valve. Check for proper throttle movement and operation. Then, re-assemble. The cost for a throttle body cleaner is $4. Figure 2.

How to troubleshoot a hesitating or bucking car?
Step 1: Physically inspect the fuel filter. If the fuel filter is dirty like the image on the right, it’s probably causing a restriction of fuel flow to the engine and should be replaced. Step 2: Check for leaks coming from fuel filter connections. The fuel line is spliced between two fuel lines.
Why is the Check Engine light on on my Honda?
A simple mistake in servicing these systems can cause a poor idle. And if your check engine light (CEL) is on, this may also indicate that a sensor might be bad, causing the engine to compensate by automatically adjusting the idle or air/fuel mixture.
Why does my Honda engine have a rough idle?
During start up, your engine is almost dry of oil. If you use thicker oil it will take longer for the oil to reach the top end of the engine. Because of this, the cam and valve train do not get oil for some time during start up. When this happens, the parts wear faster and eventually cause things like rough idles.
What happens when the PCV valve fails on a Honda?
Usually if the PCV valve fails in this manner, you’ll experience a ‘high’ or ‘hunting’ idle. An easy way to find one of these faulty PCV valves is to pinch off the supply line to the PCV valve with a pair of pliers while the engine is at idle.
Why are my spark plugs yellow on my Honda?
An irregularity or a spark of any other color (blue, orange, or yellow) could be a sign of ignition coil or distributor trouble. Follow this procedure with the remaining spark plugs. Replace the spark plugs with high-quality Honda-approved plugs like NGK or Nippon Denso. Replacement plugs start at $12, and run up to $50 for performance plugs.
Which is the best spark plug for a Honda Prelude?
New Prelude performance spark plugs often result in benefits such as better fuel economy, smoother and more energetic starts, less harmful emissions and many more. Spark plugs use a ceramic insert to delineate the high voltage at the electrode, making sure the spark happens solely at the electrode tip and nowhere else.
