When I'm coming up on a stop I push the clutch in and my rpm's drop to about 200 and my ac compressor turns off. After I have come to a complete stop and my rpm's go back up to normal the compressor will come back on. What could cause this? I thought after I got my computer reflashed it would fix this but it didn't.

Mods are:
3/8" plenum spacer
HFC's
Y-pipe
3in. single exhaust
CAI

 

Try Cleaning out your MAF sensor. There is a very simple DIY. It only costs a few dollars for the cleaning spray and the microfiber cloths. I had similar issues a few weeks ago and it cleared it up right away. Good Luck.

 

Ok I will try that
