It's a 2001 Chevy Blazer with 100k miles. About a month ago it started to make this grinding/clicking noise during acceleration. I'm usually the DIY kind of guy so I started to research what it could be with no success. There's so many things that just didn't fit. I read some where it might be the ignition coil. But recently, my car would die from hitting hard bumps in the road. Car would start up again but would stall once I hit another hard bump. Any suggestions?
That sort of noise is normally associated with cv joint or "U" joint in drive line failures
engine stopping after hitting bumps indicates loose ground wires , loose battery terminals , loose or dirty wiring harness connections
Yes, you need a brake job or clean the brake pads by taking off the tires, then the drums, wipe the inside of the drums of dirt, wipe the brakes off, and reassemble.

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

Sounds like your A/C compressor is seized up and stalls the engine through the belt train when the compressor clutch kicks in.
Try turning the compressor by hand (not from the pulley but from the front part (magnetic clutch), if you can't turn this by hand, it means the compressor is seized up...
As for fixing it, the actual fix would be to replace the compressor assembly, but believe me, that is usually not a cheap fix...
If you want the cheap fix, find the 2 wires that go to the compressor clutch (there is usually a plugin close to the compressor), unplug it and/or cut the wires and secure them to make sure they don't short out anywhere, or even better find the fuse for the A/C and take it out. Of course then the A/C won't work, but the clutch will not kick in and stall the engine...

Hi Chris, I've been trying to imagine the noise you're reporting and I'm having difficulty? I'm wondering if it could be a intake ducting which is collapsing when you accelerate and thereby causing a restriction in the intake manifold? You did not mention any other symptoms which occur and that would be very helpful. Does the vehicle lose power when this happens or is the performance unchanged? How is the fuel consumption? You describe the sound as a grinding or clicking sound? How loud is it? Do you need to concentrate to hear it or is it very prominent? Which area does it seem to come from? If you can report any other problems you've noticed in addition to those you've reported that will help us too. Let us know the answer to these questions and we hopefully will be able to give you some help. Regards John
Hey John, the sound seems like it's coming from behind the dash. It's more like a grinding sound that is actually pretty loud. My brother and I opened the hood and was trying to pin-point where the sound was coming from exactly but we can't find it. Fuel consumption is still the same and performance is unchanged during the grinding sound. The only other problem was how the car now dies out completely after I hit a hard bump. Car dies out, and I have to pull over to the side and start it up again. If this occurs a few times during one trip, I have to keep the engine throttling in order to keep it from dying out again. Do you think they could be related?
