this does sound like theres a loose line tapping the engine/frame,during warm up the engine idles faster which could make it vibrate faster causing the the clanking or tapping noise,if this has started after trans fluid change,then check the lines running from the trani to radiator sometimes the service person might bang into something causing plastic clips that hold the lines to break,try getting under it and have someone start the truck and listen to see where it's coming from also hold the lines & see if the noise stops,the service guy could have unbolted something & never put the bolt back causing the clank ex.line may have a clip holding it thats bolted to the trani pan ?good luck
The rattle is caused because the rpm is lower. When stopped in drive with one foot on the brake, press the throttle down slowly until the vibration stops and the noise goes away. Cause? Weak or bad motor mounts, loose bolts or parts.
may be a camshaft chain problem your aj26 or aj27 engine is prone to broken chain tensioner/guide problems they are plastic you need to go to a speciaist jag/engine person . good luck
try a oil additive from "Lucus". add it to the engine when you do next oil change. this additive is as thick as honey. it worked good for my lincoln. helped with compression.
HI MY NAME IS JUAN:
I HAVE A 93 BUICK SKYLARK CUSTOM
AND I HAD THE SAME HESITATION.
I CHAGED GAS FILTER, AIR FILTER, AND USE SEA FOME IN MY GAS TANK AND USE IT ALSO TO CLEAN THE INTAKE SYSTOM, AND IT HELPED ALOT. TWO MONTHS DOWN THE LINE HADE THE SAME HESITATION AND IT WAS ONE OF THE INISION COIAL PACK WAS NOT GIVING THE ELETRICAL SPARK TO THE PLUG. I CHECK IT BY PULLING THE CABLE OFF THE SPARK PLUG WITH THE CAR RUNNING AND FOUND THE ONE THAT WAS NOT GIVING SPARK. I REPLACED THE PACK FOR THAT CILINDERS PLUG AND THE PROBLEM WAS GONE.
HOPE THIS CAN HELP YOU.
pullys have bearings and the bearings will go bad. what you need to figure out is what pully is makeing the noise and replace said pully. another problem you might have is the power steering pump. check the fluid level to make sure it's not low or dry. when a power steering pump goes bad it makes some noise. another possibale problem is if the car has a/c. the a/c compressor has an internal clutch that will make a grinding noise when it goes bad. To test this start the car turn you a/c on or your defrosters on and listen for the noise in the lower front area of the engine compartment (usually the lowest front pully). shut off the car and look for metal shavings on the pully. for this you should take the car to someone to evacuate the system so you don't release refridgerant into the atmosphere (it is also very flamable) and will need to be oiled with 134a oil and recharged after the repair. hope this helps.
hi try taking the air filter pipe off the throttle body see if the butterfly spindle has no play in the spindle or the retaining screws that hold it to the spindle have not come loose just put your finger on the butterfly while its idling see if the noise goes if not just pinch the vacuum hose on the vacuum box see if noise goes or changes pitch yates210456
