Hi!!

It sounds just like a vacuum leak. If you checked all lines and hoses it may well be a intake gasket leak or cracked intake.

Usually a leak like this will give you a Trouble Code and the Check Engine Light comes on. If so, drive vehicle to an AutoZone or Checkers for a free scan of the codes, that will help to pinpoint the problem.

Good Luck!

Tune up


You need to study or research info on tune-ups
Basically it is a sales pitch, as only spark plugs are left
& tune-ups stopped 25 years ago from a technical perspective
Your not actually tuning anything
You replacing old spark plugs,gas & air filter etc,that has been
called preventative maintenance for over 20 years
For the last 30 years the vehicles Computer does all the
engine tuning

How to adjust valves on chevy tahoe99 v8 4wheel drive 5.7


Adjustiyour hydraulic lifters with the engine running Startt the engine and allow it to warm up. Begin to loosen one of the rocker arm adjusting nuts. You should hear the valvetrain just start to "clatter". Slowing tighten it down until the "clatter" just stops and then turn it 1/4 - 1/2 turn additional to set the plunger depth (lifter preload). Continue this procedure on all the valves. If you hear excessive noises or the vehicle runs crappy you will be doing the procedure again. As stated above, if you have access to a mechanic's stethoscope, you can set the end at the top of the rocker stud to listen to the noise a loose adjustment makes, which will make finding "zero" lash easier. I have an old set of valve covers with the top cut out to minimize the mess.

Our truck is a 2000 Chevy Silverado 1500, shortbed. About 1 1/2 years ago, it started making a "fast chirping" noise under the hood. It doesn't matter if we are idling, driving slow / fast, or braking,...


Start by isolating the issue. Remove the belt and start the engine. If it is still there, it is likely resonating through the engine from the flywheel/flexplate. If it dies, spin the alternator. This was a problem in some of there cars. Let me know what you find.

How do I loosen the serpenteen belt on my 2000 chevy silverado 1500? I need to replace the alternator.


If it's a v8 then when looking at the engine the top left pulley has a 15mm bolt holding the pulley on. Use an endwrench and move/pull it to the drivers side of the truck!

With your Clarifications I suggest having the Fuel Pump Pressure Tested as one other gentleman suggested that it is most likely bleeding down overnight. Another possibility would be the Fuel Filter being clogged. The factory recommendation is to change fuel filters every 30,000 miles. Many people do not even know a Fuel Filter exists on their vehicles. Some years back they were near or in the carb. Weak Ignition would be the last thing to look into as the vehicle runs somewhat normally once started and running for a while. Modern vehicles have Electric Fuel Pumps inside the Fuel Tank. This is somewhat expensive to replace but necessary maintenance after many many miles. Good Luck!

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.
