What is this 'Trumbler' that you changed?? Not even Google has a clue!
Are you losing coolant? Did someone put Windshield Washer fluid into the engine oil filler? You are burning water. The ECM doesn't like it so it it shakes. At idle there isn't as much pressure to stop the water entering the combustion chamber. Likely a failed cylinder head gasket. You can do a pressure test and there is also a test that identifies exhaust gases in the coolant.

Inspecting your other problems first:(as yo replaced you MAF)
Take a real good look at the throttle "butterfly" valve. They have a
tendency to get buildup with dirt and will stick slightly open,
confusing the computer into thinking that you are pushing on the "go"
pedal. Get some carb cleaner, or even better, GM Top Engine cleaner,
and really clean out the throttle valve and air intake area. I have
seen several similar problems fixed this way. If this does not take
care of it, it may be worth paying someone an hours labor to hook up a
good scanner and see what is going on. You can waste a lot of money on
the newer cars throwing a lot of expensive parts at them and still not
fixing the problem. It could be a simple loose connection somewhere. A
good tech can catch this type of stuff with a good scan tool.
Always check the fuel pressure .
It might be the in tank fuel pump or clogged filter
checking that can be done by you easily:
you might check the ground wires that are located at various places on the engine
check your IAC valve (idle air control), this is located on the
passenger side underneath the throttle body. These get all carboned up
and can't re-seat themselves properly. You may have to perform a
minimum idle setting also. This isn't to hard but is more complicated
than on a non-computer controlled
MAF signal checking:
I used a small straigt pin and shoved it in the back side of the MAF
connector on the signal line. I started the motor and expected to see
the voltage signal to start low at idle and increase smoothly with
engine speed. Instead what I saw was a stead 5 volts meaning the ECU
had supplied the bias signal but the MAF wasn't loading it down to
generate the signal. The issue was that the MAF socket pins in the
connector were slightly sprung and had a thin layer of oxidation on
them. I tiny rolled up piece of sand paper buffed the terminals up. A
tiny pick probe was used to squeeze the socket pins closed slightly. A
light doping of dielectric grease kept the moisture out and it's been
running fine for 5 or so years no
Hope this helps,kindly RATE ME
97 Malibu. V6-3100. Starter turns engine, but car
I think you may have answered your own question. I would check to see if the fuel pump is turning on when you turn the key on to the run position. You should hear a buzz sound coming from the gas tank. I would start there.
2004 Chevy Trailblazer idles rough.
If it has not pulled any codes (idiot light). Clean your throttle body, and change your spark plugs with A/C Delcos #41-103, most other brands will cause rough idle like Autolites and Bosch. This would be a cheap way to fix this problem.
If by chance you have just recently changed the battery or had the battery unhooked. Let me know, it's an easier fix that costs virtually nothing.
Are the head lights on all the time 1999 chevy silverado 1500 4x4
In the 1999 Chevy Silverado 1500, the headlights are not designed to be on all the time by default. They are typically controlled manually by the driver using the headlight switch, although some vehicles may have a daytime running lights (DRL) feature. If the headlights are continuously on, it could be due to a modification or wiring issue, and it's recommended to consult the vehicle's manual and seek professional assistance if needed.

Torque specs for inner joint bolts to diff. 2004 chevrolet 2500 4x4 front axle
The torque specifications for the inner joint bolts that connect the front axle to the differential on a 2004 Chevrolet 2500 4x4 may vary slightly depending on the specific model and components used. However, I can provide you with some general torque guidelines.
Please note that it's essential to consult your vehicle's service manual or contact a qualified mechanic for the exact torque specifications, as they can vary depending on factors like the specific front axle design and any aftermarket modifications. Here's a rough estimate:
- Inner Joint to Differential Housing Bolts: Typically, the torque specification for these bolts is in the range of 85-100 lb-ft (115-135 Nm). However, it's crucial to verify the exact torque value from your vehicle's service manual.
Always use a reliable torque wrench to ensure that the specified torque is applied accurately, and follow proper tightening sequences and procedures as outlined in the service manual to prevent over-tightening or under-tightening, which can lead to problems with the front axle and differential.
Where is the starter located on 89 corvette
The starter is located on the passenger side where the engine mates with the transmission. It's held on by two bolts and there are wire harness that need to be disconnected and are live so you need to disconnect the battery ground first. Good luck and hope this helps. Keep me posted if you need instructions to removing the starter or you can log on to Auto Zone and register free of charge and you can get a print out on how to get the job done with common tools. Be safe friend.
