Why does my truck idle but no power on acceleration?

The EGR valve tested correctly and wasn’t replaced. When I start the truck (starts easily) it will idle at around 1000-1100 RPM for a about 30 seconds and then drops to about 600 and then to 500 and then stalls. It will staying running if the accelerator is pressed but it is weak during acceleration.

Truck will not go over thirty mph. The fuel cuts out and starts to sputter at 2000 rpm all the way to 3000 rpm. I have changed plugs, MAP, TPS, IAT, crank sensors, wires, cool pack, cool mod, fuel pressure, fuel pump, crank, timing gears and chain ECM/ECU.

Why is my Vortec 6000 engine not working?

When water enters the sensor it corrodes the wires and causes the whole sensor to fail. Rough idling, poor driveability, performance, acceleration, etc. The 6.0 engines have variable valve timing, which means the computer electronically adjusts timing when it believes it is off.

How long does a Chevy 6.0L Vortec engine last?

Chevy 6.0L Vortec Reliability Overall, the 6.0 vortec is an extremely dependable and reliable motor. These engines frequently last beyond 300,000 miles with minimal issues beyond regular maintenance. However, making it to 300,000 miles will likely require some non-engine repairs and maintenance, such as suspension components.

What kind of gas mileage does a 6.0L Vortec get?

Despite a lack of power, a few bolt-on mods can give your stock 6.0L vortec a nice pick-up in power. Lastly, the only complaint on these engines tends to be gas mileage. These engines tend to get 10-12mpg, although some owners claim up to 16mpg.

Why is my car rpm reading so erratic?

If you are getting erratic readings, this can be a sign of bad wiring. Another potential problem is calibration issues. If you notice the RPM readings do not coincide with the motor, then it may be time to have the mechanic look at the vehicle.

What to do if your car won’t accelerate?

You might need to go to a mechanic for a proper diagnosis. If your accelerating won’t go past 40 mph, then there might be a problem with your exhaust pipe. It might be blocked; you will need to take it to the mechanic. You can also test your fuel pressure or try to do a compression test.

What happens when engine RPM drops below 800?

However, when the engine RPM drops below the normal range of 800 RPM (for most cars), it is more than likely that you are dealing with an IAC valve problem. In cases where this valve is clogged or is failing, your vehicle will stall instead of slowing to an idle after the release of the throttle.

Malfunction of Sensors such as: Oxygen sensor, MAF sensor, Crankshaft sensor.

Why does my car not accelerate when I press the gas pedal?

This sensor sends a reference voltage to your power-train control module, which uses that to determine ignition timing and fuel trims. If the power-train control module is not detecting the proper signal from the throttle position sensor, the engine may not accelerate properly.

Why does my Car start accelerating while in neutral?

Your car can also start revving while in neutral or in park on its own. Here is why this is happening: ”If your car starts accelerating by itself it could mean only one thing: If your older model car starts accelerating by itself its because the throttle cable is stuck.

Why is my motorcycle not accelerating at high speeds?

More firing is performed at higher speeds whereas slower speeds have less firing. The engine timing is the mechanism that controls this. If you have poor timing advance, spark plug firing becomes delayed and isn’t timed right which will cause your motorcycle to not accelerate properly. This will probably be accompanied with some backfiring.

What causes a motor to idle but not accelerate?

If you see the jet spraying into the carb when you hit the primer, then you know the fuel pump isn’t delivering enough volume or pressure, and that’s your culprit. If not, then, it’s an issue with the carbs. Good luck with it. Fishing, jet skiing, target shooting, jet-boating, and even a little oyster harvesting with Larry The Cable Guy.

Why does my diesel engine run but not rev up?

If not it could be the pump. This is of course running it from a can, bypassing the fuel lines and filter. Let it run until the entire can is in the pump…let the feed and return go into the diesel purge can and run it until it is in there. Shut it down and let it sit a day or 7 and try again.

Why is my Duramax diesel engine not working?

The trucks computer keeps track of how much fuel needs to be added or subtracted from each individual cylinder to make the engine run smoothly, and this value is called the balance rate. If one cylinder is contributing too much or not as much as the rest, the cause is usually a bad injector and the cure is a replacement.

What’s the difference between rpm rev and no acceleration?

RPM rev and no acceleration? I have a 2004 Hyundai Sonata with about 85,000 miles. For the past few weeks, when trying to accelerate, I press down steady on the gas pedal, and sometimes the car does not accelerate. Also, the RPMs rev very high from about 2 to sometimes 5,000 (all with no acceleration).

If your Altima won’t accelerate, but the RPM’s go up it’s usually not going to be an engine related issue. Somehow, the power that your engine is creating is not making it to the rear wheels. This is typically a transmission related issue. Here are the most common cause of acceleration with the RPM’s going up:

Why is my car revving at high RPMs?

But, to answer your question… No, a clogged fuel filter would not explain an engine that is revving at high RPMs without the car moving at an appropriate speed. The most likely explanation would be a failing transmission if it is of the automatic variety, or a slipping clutch if it has a manual transmission.

What happens when car RPMs are running high?

When your car RPM is running high, it causes rough idling which means your engine may shake or vibrate while it is running. Your driving experience will not be comfortable. There are many reasons why the RPMs might be running high. The first thing to do is to check for bad spark plugs. If your plug is damaged it might cause your RPMs to run high.

What to do if your rpm gauge is not working?

Check the charging system and see what’s going on there. you should have 14-15 volts going to the battery while the engine’s running (accesories off). if you don’t, you should check the stator to make sure it’s ok, or just replace the voltage regulator. they’re about $150. it’s best though to check stator output and make sure it’s not a bad stator.
