I am not sure how I can check under the bonnet since it only shakes and shimmies while I am in drive. If it is clutch/ compressor related then I will take it in to the mechanic that did the original work.

They are new. Talking to my mechanic he says what you said earlier that maybe the clutch isn't engaging causing the serpentine belt to not cycle thru and then shake the vehicle and cause it to shut down. I wont be able to check this problem out until I get it over to my mechanic and see what he says. I will check behind the bezel soon as it is starting to get hot and I wont want to be in this hot heat.
Next thing I have you may be able to help so I am putting it out there. From a start I will give it gas and it will bog down like I am down a gear but its an automatic and hasn't down shifted at all. Eventually it will stop doing that and go back to normal. It doesn't last long maybe 100 feet. It almost feels like the exhaust has a clog, but it doesn't do it all the time maybe 1 time in 15 starts maybe less maybe more as I really don't keep track.
The other thing it does is surge which I believe is the TPS. This too doesn't happen all the time, maybe as much or less as the issue above. I have not changed my IACV sensor or my TPS. I believe this will help with my issue. Will it help get batter fuel mpg? I put in a new MAP sensor but haven't gone thru a tank of fuel to see any improvements.

Actually, I have the same issue. Never on a cold start. Usually after I have driven it about 5 miles and stopped at a store. It never happened until I upgraded to 4 hole injectors so I assumed it had something to do with that. It hasn't really caused any problems as it "cures" itself before leaving a parking lot.
As far as your TPS and IAC....You can clean your IAC and throttle body....but the TPS, from what I understand, is a non serviceable part, just a replace part. Many videos exist on how to do the above service.
Which by the way, didn't help with the parking lot hesitation....

I believe mine is on a cold start but its never really all that cold here. It just did it to me the other day and it was near 80. I don't have 4 hole injectors unless those are OEM. I haven't changed out my injectors and have almost 160k, should I and what should I change them to?
When I had to change my MAP sensor it was pretty basic so doing the TPS, cleaning the throttle body and getting a new gasket if it needs it. Having a new TPS will that help with the MPG's?
The coincidence of the blower motor acting up after your a/c "rebuild" may not have anything to do with the other. First, besides adding more Freon, what was done to the a/c system to rebuild it? As member AWG stated, you may want to visually inspect that the compressor clutch is engaging when you turn on the a/c. Also adding to much Freon is bad for the compressor and the system overheats.
Your electrical problem probably starts behind the dash...specifically the fan speed control switch.
Don't be surprised if you find this.
This morning before it got too hot I went out and removed the bezel for 2 reasons. One my stereo needed replacing and two the fan controller switch. Mine looked just like the one in the picture above. Since it appears to be a problem, how do you stop it from happening again and where do you get another connector like that one?
Start by checking the wiring to the fan selector switch on the dash. The switch and/or wiring connector is know to fail and melt/burn. My Jeep had the connector melt. I did not replace the connector, I attached thermal connectors to each wire and replaced the switch with a new one. Make sure, if you do this, that you know which wire goes to which terminal on the switch. Make a drawing and take pictures for reference.
