I had the engine running with the A/C compressor on while I was under the hood. I've never had it on while I was working under the hood before this.
As I race the engine, the compressor vibrates forward and backward, enough to see it very visibly.
I checked the bolts on the brackets to the engine, and the bolts on the compressor to the bracket. They are tight.
When my engine was rebuilt, they had to recharge the A/C. Could this be happening because it's overcharged and laboring the compressor???
Also, the A/C belt is very tight, more than I would like to see -- could the belt be too tight and the compressor is vibrating because of that???
Any ideas -- or can someone with an A/C unit run their A/C and race the engine from under the hood to see if this compressor vibration is common?? Asking alot, I know.
