Is your Check Engine light on? If so, I suggest running the self-diagnostic procedure with your ECU. It might indicate a bad fuel injector, which have a tendency to work sporadically when they are failing. This causes a very noticeable hesitation, especially at cruising speeds. Unfortunately, this would be a costly repair. I hope this isn't your problem, though it's happened to my 1990 N/A on two separate occasions. Runs like a charm again when fixed though.

They are bolted to the exhaust manifolds, pretty much hugging the engine on the outside of each head.
It would take a long time to explain, so please refer to the 300ZX service manual. It is available for free on the internet, just do a google search for it. I'm not trying to be condescending.
Perhaps starter is getting weak and needs replacing--takes more effort to start hot engine
You don't have an airbag
Check the crank position sensor
No. None of the Z32 300zx's have them. (1990-1996) There is no option for it either. The only thing you could do is buy an aftermarket wheel that is smaller.
1,000 to 2000 depending on condition of engine
A clog in the radiator will do this.
you have to remove the motor and it still a painfull time consuming job
A 91 engine will not fit in a 98 Escort. The 91 engine is from a generation II Escort whereas a 98 engine is from a generationIII Escort.
There are two, they are bolted to the left side of the left head and the right side of the right head.
