Just sayin
( BTW: these are the same symptoms I get if I forget to plug the MAF back in when I have the CAI off - did that once when I had it off for some fresh silver paint )

Well, if people cannot safely use ether then your correct and just bring it to someone else. Just saying... I did say 'lightly', just took for granted the person operating the can would not look into the nozzle and press the button.

OP didn't mention anything about having the MAF unplugged did he? Sometimes I just read too fast... It is a good idea to check the MAF connection as wires/connectors sometimes loosen up. Just hope it isn't damage caused by water or moisture buildup. If it is, it may be elsewhere...
