Why doesn't right wheel work?

Well I edited the post a bit and corrected spelling, and I have read it 6 times. I see a lot of stuff that isn't relevant and still wondering why you are waiting with a radiator cap in your hand :>)

So you had a lot of coolant leaks, you have them fixed and you were worried about the water pump, so you told them "while you have the car up on the hoist for the wheel bearings, change the pump please". They did that, they lost a fixing bolt, but they found another. Now the car misfires.

Well the water pump and the coolant system don't affect how the engine runs. The only thing I can think of is that when they changed the water pump they disconnected some wires that were in the way of the pump. Maybe the Crankshaft Position Sensor is down there and wasn't connected firmly.

Shops shouldn't be charging $280 for plugging in a scan tool, my tire guy does it for nothing, having said that, the Lexus Dealership charged my $238 for a $40 plain wheel bearing!

The water pump is not easy to get to

Misfires should display a code

sounds like the transmission is not going in netural check and see if there is a blokage or is out of adjustment.

you have a bad power stering pump you might try taking fluid out using turkey baster trning wheel all the way to right or left and add little at a time while rotating it rt & lf till it squeels each direction allowing fluid to fill the rack & pinon if you have a rack & pinion cylinder on this auto if it ran dry and it's not purged ti will act like what you are discibing add a little start turn lf& rt few times turn off do agian til you top it off. good luck ckeck youtube video.

get it off the groud rear wheels put a weight on forward drive if it works fine if not with the weight still on start turning wheels by hand if it work let run like this 30 minutes if not did you use the right fluid not transmission fluid if you did buy new hydrostatic pump buy one any way pumpsounds like bured up 200 dollars for pump before you do this isworth it if mower over 4 years buy new mower you will save a lot of money in long run

First check to see if you have any leaks especially on the problem let side. This includes the wheel motor. where hydro oil comes out, air can go in. either way it sounds like you need to take your pump out and open it up and check for metal inside. If you do not have any metal inside check the 5 pistons to see if they are stuck. What series hydro pump do you have?
10L 10A etc.

It sounds like you have blown out the speakers.

first check the oil level it may have a low oil shut off then swap the safety switch from side to side

first check to see that you have enough hydraulic fluid in the resevoir and that the right side hydraulic pump is not leaking....there is the possibility that the lever that controls the right side is slipping on the shaft where it connects to the pump causing this condition...if you have the manual the mower came with ..you need to go to the procedure for bleeding the air out of the pump....if it is not in the manual, you can call a dealer for the instructions or order a service manual....if all the above does not fix the problem... then you may need to get a rebuild kit for the hydraulic pump...these are not too expensive..but they beat buying a new pump as pumps are anywhere from 400-700 dollars

Did you purge the hydro system after the service/repair? At the shop we always jack the rear of the mower up,start it and engage the drive levers and let it sit for 15-20 minutes to get the air out of the pump,wheelmotors and lines.

Two possibilities: This is a stove orificed for propane and connected to natural, or the regulator ( a squarish shaped thing in the line under the cooktop) has a problem and is limiting gas flow way below normal. In the first case you just got the stove, in the second it has worked fine until the sudden change.
