If you are meaning that you are having to spin the starter longer to get it to crank on a cold morning then more than likely the coolant temperature sensor needs to be replaced. There are two sensors relating to the temperature of the engine. One gives a signal for the guage and the other for the computer. The one for the computer should be right beside the thermostat housing. It is what tells the computer that it is cold and the computer adjusts your fuel for a cold start.
Yes....try Hypertech or JET.
Does it have enough compression?
My 89 Corvette which is also a C4 recommends 35psi on all 4 tires
no, the hinges are different and size
No. There are three different tops for the C4 Corvettes, 84 to early 86, late 86 to 88, and 89 to 96.
On 1984-1989 Corvette, the dash top grilles only housed speakers if the car was not fitted with Bose stereo, about 10% of production. TOM
Inside the distributor
They're all 350 cubic-inch small blocks in 1989.
Pull the housing off at the gas fill, it's under there

They are the same, however, I have to advise you here, there are federal laws about odometer tampering, so you better check them, and apply them to your situation, before proceeding.
Hot or cold is relative. Certainly 89 degrees Celsius is very hot. But 89 degrees Fahrenheit is pretty warm, but not exactly what most people would call "hot". Consider that water boils at 212 degrees Fahrenheit, so 89 isn't hot compared to that.
