WILL 87 OCTAINE FUEL CAUSE AN IDLE PROBLEM.
Experienced athletes share their insights in answering this question:
I have alot of trouble in my shop with the 87 fuel. Carb problems is #1 along with sticky valves. Go to a higher octaine!!
How to Identify and Resolve Common Issues ?
We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :
A rough idling engine can be caused by spark plugs or spark plug wires. Spark plugs use the electrical current received from ignition coils to ignite the air/fuel mixture within the combustion chamber. A plug that is damaged or installed incorrectly can result in fuel being burned at an inconsistent rate.
Cleaning out the carburetor to remove carbon deposits is probably a good place to start. Then you should check all the vacuum hoses – a leaking hose can cause a too-lean mixture and a rough idle. Other places to check in older vehicles are the distributor cap and rotor in the ignition system.
How to fix it? Cleaning or replacing the fuel filter and adding a fuel injector cleaning treatment to the fuel tank should take care of clogged fuel injectors. If the rough idle persists, it`s time to take your car to an auto repair shop.
While it may seem like a small problem on its own, rough idling is a sign that some part of your engine isn`t working properly. Over time, rough idling can result in poor gas mileage, starting issues and major engine problems.
Along with faulty spark plugs, a build-up of dirt and grime is the likely cause of cars stuttering when idle. A clogged filter or fuel injection system can starve your engine of fuel or oxygen, causing your car to judder and shake.
The idle speed should feel consistent without skipping or slipping. In most of today`s cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won`t feel smooth. The RPMs will jump up and down, for example, or they`ll fall below 600 RPM (or whatever is typical for your vehicle).
Simply put, a rough idle describes an engine that is not firing consistently when your vehicle is in park, with no gas applied. Most vehicles idle between 600 and 1,200 RPM and should hold their idle speed.
A dirty air intake or cracked air intake tube is often the culprit.
Typically, engines idle at about 600-800 rpm. Older engines may go up to 1200 rpm or more while warming up. But if the engine is revving up while idling, even after it`s sufficiently warmed up, you might have a problem.
Oil changes keep your car engine running smoothly. Rough idling, slow acceleration, and engine noises mean you need to replace your car oil.
A rough idling engine is a clue that some part in your vehicle isn`t functioning properly or may be failing. Besides wasting fuel and other drivability issues, a rough running engine should be promptly diagnosed and repaired to prevent engine damage and ensure your driving safety.
The most common causes of this on your vehicle are either a bad idle control valve, a dirty or failing throttle body, or a vacuum leak. It is very common for the engine to have a vacuum leak at the intake manifold gasket. I usually start by checking that first for leaks.
The car may be louder than normal, or you may feel shaking (in more severe cases). When you put your car into park or neutral , the engines idle control valve maintains a specific idle speed, allowing your car to use minimal engine amounts of fuel.
A sputtering engine means that it is not achieving full combustion. It could be the sign of a very simple problem or it could be a symptom of a much more concerning engine, fuel system or exhaust system issue.
No rpm is bad for an engine as long as it`s under the redline. It`s as simple as that. So if the redline is at or above 6000rpm, you can happily run it at 6000 rpm if you`d like.
Normal idle speed for your vehicle, once the engine is warm, should be around 750 RPM (roughly). Two thousand RPM is significantly out of range high, even for a cold engine. The occurrence of this high idle speed might be a coincidence and thus not related to the alternator repair.
RPM fluctuation is a common issue for cars with faulty spark plugs as they fire the fuel with the pistons. If they wear out, your acceleration slows, and jerking and misfire start occurring, which, in combination, causes poor fuel economy and vibrations.
Replace the sensor with a compatible one and correctly install the crankshaft position sensor to ensure that the engine runs optimally and safely. A qualified technician can prevent further issues with RPM fluctuations while driving by installing the sensor correctly.
If your car hesitates or sputters at a low RPM, you could be dealing with an issue with your engine`s air filter or there could be an issue with your fuel filter, injector, or pump. The best thing you can do is take your car to a mechanic so they can properly diagnose the issue and repair it.
Incorrect Idle Speed: While the average idle speed falls between 600 to 1,000 RPMs, if your vehicle is experiencing a rough idle it could be due to an incorrect idle speed setting. A trained technician can easily adjust the idle speed, and it should stay at the proper speed.
Zero. There is no direct correlation. You can rev a motor in neutral or park to 2,000 rpm and get 0 mph.
When a cold engine is started, a component called the auxiliary fuel injector sprays additional fuel into the intake manifold. The extra fuel helps the engine start faster. But we also do not want the fuel-air mixture to be too rich. So, the throttle valve opens to raise the engine`s idle speed.
4000 rpm is no problem, high rpm can wear down on the head where the camshaft rotates but that`s no really a problem until you get near 7000 rpm.

I have a polaris snowmobile and it starts up great, idles fine, but after running it about 200 yards or for about 30 mins it dies and wont start up for 10 mins or so. What could cause it to do this,
ANSWER : The problem is the needle valve in your carb is partially clogged. It’s not letting enough gas into your carb fast enough. You let it sit for 10 mins and it slowly fills the carb’s bowl back up. Then you ride it and it empties the bowl of gas faster than the needle valve can keep it full and the snowmobile dies. Get the carb cleaned and it will fix your problem
