Question about 2000 Chevrolet Silverado 1500

Open Question

Hesitation between 40 and 60 mph

My truck has about 180k miles and seems to start up fine. The truck runs fine at lower speeds, however as soon as i reach 40 mph the truck begins to hesitate in a jerking manner. Its almost like the transmission cant decide which gear to go in. It especially does this while going up an incline at speeds of 40 mph or higher. Has anyone had similar problems or have any information that could help me diagnose this problem. Thanks

your transmission has possibly been rebuilt with stronger springs put in. No worries. have been running mine for along while without any problems. Better this than slipping, but it is a bit annoying.

SOURCE: downshift hesitation?

Sounds like a plugged catalytic converter or in rare cases muffler. This will set codes but try this; remove O2 sensor closest to front of catalytic converter, it will be noisy but drive again, if performance is better, suspect plugged catalytic converter,replace cat and reinstall O2. Also check air filter and mas air flow sensor. Have had some luck carefully cleaning sensor with throttle body/air intake cleaner after removing from vehicle with key off. Hope this helps ! Rate me please.

SOURCE: Engine surge at 45-55 mph on 2002 Silverado 5.3l engine

I would start looking for a vacuum leak. Check all the vacuum lines for cracks or breakage. Spray penetrating fluid on them until you hear the engine start to stumble then focus the spray on that area until you are able to pinpoint the location of the leak. Best of luck,my friend, Dana

SOURCE: My 97 Suburban starts fine if driven everyday. If

Your fuel pump is in the tank and the fuel pump check valve is is malfunctioning. You need to replace the fuel pump. To test newer fuel pumps like your you have to put a gage on the valve you pressed in and turn the key on and look at the fuel pressure if it goes to 50 PSI then turn key off if it drops below 20 psi with 30 seonds the fuel pump check valve is bad. Replace with OEM part from the dealer. after market part fuel pumps burn up quick. also change the fuel pump and fuel filter. this is a 4 hour job for a first timer mechanic the pump is causeing all of your problems. Let me know if you want detailed information to repalce the pump. it cost about $195.00 does it have duel tanks? if it does the switching valve may be defective as well.

Tip

Save Money on Gas/Petrol


  1. Avoid idling. While idling, your car gets exactly 0 miles per gallon while starting the car uses the same amount as idling for 6 seconds. Park your car and go into the restaurant rather than idling in the drive-through. Idling with the air conditioning on also uses extra fuel. Also, avoid going so fast that you have to brake for someone. Whenever you brake, you waste the gas it took to get going that fast.
  2. Drive at a consistent speed. Avoid quick acceleration and hard braking. Cruise control will keep you at a constant speed, even when going up and down hills.
  3. Avoid stops. If approaching a red light, see if you can slow down enough to avoid having to actually stop (because you reach the light after it is green). Speeding up from 5 or 10 miles per hour will be easier on the gas than starting from full stop.
  4. Anticipate the stop signs and lights. Look far ahead; get to know your usual routes. You can let up on the gas earlier. Coasting to a stop will save the gasoline you would otherwise use maintaining your speed longer. If it just gets you to the end of a line of cars at a red light or a stop sign a few seconds later, it won't add any time to your trip. Ditto for coasting to lose speed before a highway off-ramp: if it means you catch up with that truck halfway around the curve instead of at the beginning, you haven't lost any time. In many cities, if you know the streets well, you can time the lights and maintain the appropriate speed to hit all green lights. Usually this is about 35 to 40 MPH.
  5. Slow down. Air resistance goes up as the square of velocity. The power consumed to overcome that air resistance goes up as the cube of the velocity. Rolling resistance is the dominant force below about 40 mph. Above that, every mph costs you mileage. Go as slow as traffic and your schedule will allow. Drive under 60-65 since air grows exponentially denser, in the aerodynamic sense, the faster we drive. To be precise, the most efficient speed is your car's minimum speed in it's highest gear, since this provides the best "speed per RPM" ratio. This is usually about 45 to 55 miles per hour.
  6. Use A/C only on the highway. At lower speeds, open the windows. This increased the drag and reduces fuel efficiency, but not as much as the AC at low speeds (35-40 mph). The air con - when used a lot - is known to use up about 8% of the fuel you put into your car.

Driving between 35-50 mile ph truck will start vibrating


There are many stages of vibration. The most common is in the steering and USUALLY a steering dampner will correct this. However, your description is not real defined and until the technician actually experiences it, it cannot be properly diagnosed

Speedometer gives false reading after car warms up


Check that the body ground is clean and tight. I'm talking of the connection to your instrument panel. This connection be loose or corroded can make for improper impulses and incorrect readings. Lower impulses at lower speeds may be correct because it doesn't need the power as much for slower impulses. Only makes sense.

At 40 mph the car starts to shake. It last to 5o


I have this same car with exactly the same problem. Begins shaking at 40mph and stops shaking as soon as you let off the gas, but then begins again as soon as you press on the gas and smooths out as you get over 50. And the shaking is not felt through the steering wheel. Solution: Replace the transmission mounts. There are two of them, one on each side mounted on the frame right next to the shock strut. There is also a front and rear engine mount, but I replaced the two as described and shaking is gone.

Seem like you need to have at-least the two front tires high speed balanced. This shaking at high speed is most likely due to the tire being out of balanced. Good luck and thanks for using FIX YA
