You cannot properly set static timing on any vehicle without using a timing light. Buy or borrow a timing light.

Overfilling your gas tank is not a good thing to do. You see, there is a carbon canister that is supposed to filter the air space that is taken up by the gas as you fill up. It's purpose is to remove evaporative emissions and reduce air pollution. If your car is backfiring, it usually means that your car's engine is running rich... getting too much fuel. I would check your EGR as the ECU has the additional air from the EGR factored in to burn cleanly. If the EGR is faulty and doesn't allow the extra air to get into the combustion chamber, the engine will run rich and backfire. Replacing the distributor cap and rotor, and OEM type spark plugs every two years isn't a bad thing to do. Using long-life DENSO Iridium plugs is a better option for plugs. There is also one of two Oxygen sensors screwed into your exhaust pipe to help adjust mixture with the car's computer (ECU)... these may also require replacing with new ones made by the OEM (DENSO is the OEM). The first thing you need to consider is buying a fault code reader and a Haynes manual for your car. The fault code reader will help you narrow down exactly what may be the problems. Look in the emission control section of the manual to tell you what the fault code numbers mean. Basic fault code readers aren't expensive.

First off your 91 Prelude is not OBD2 so those functions won't do you any good anyway. Second, you said programmer?? Is this a modded PCM/car? If so I got nothing for you. I don't deal with modded cars here, there's too many variables. Without looking at it in person, there's just no way to see what you've got going.

Probably a blown fuse or a miswire. Pull the radio and revert to stock. If the fan works carefully re-wire the radio with a good diagram.
if the fan is still dead with stock radio setup you may have a short, bad relay or bad temperature switch.
if you understand electrical get a tester and start snooping.
see if any of the manuals contain good wiring diagrams.
if not its best to leave it to the pros. You dont want your car to go up in flames. If you are super concerned about a fire, disconnect your battery when the car isnt in use. SpoonerTuner com Free downloadable Honda Acura Factory Service Manuals...

Do they have any markings?
If not you could always buy or borrow a micrometer and measure the lobes. You should be able to find a lift profile on a parts website.
repair guids should have this info. There are also online repair guides.

If it is making a knocking noise, you have a problem. Take it to a service center and have someone listen to it. Does it knock while sitting still? If not, it may be something else.

1991 ?
no transmission stated, so my answers new are impossible....
why not say why you want this. the context really does help.
you or anyone can look it up. in the FSM.
many cars have 5 sensors.
here are all speed sensors
the engine has 3 speed sensors. (cam/crank speed and TDC)
the MPH (road speed sensor) is below.
my guess you have ECU DTCs for VSS?
why not state it , flat out so helper knows the full context.?
qoute FSM and alldata.com (log in and see for self)
the signal from the vehicle speed sensor is used by the ECU as well as the cruise control and automatic transaxle control units. Accords and Preludes use an external sensor mounted on top of the power steering speed sensor in the engine compartment. The power steering speed sensor is gear-driven and controls the steering boost in relation to the speed of the vehicle. An electric pulser unit is mounted on top of this unit and is coupled to it by a small shaft. The motion from the lower unit is transferred to the upper unit; the resultant electrical signal is sent to the appropriate control units.

Go to your nearest Autozone or other parts house and buy an inexpensive plug gapper. I gap the Honda plugs at .045 .

It may not be the transmission, it could be the clutch or clutch pressure plate. Try double clutching (pump the clutch twice) before shifting.
