SOURCE: Truck losing power and service engine soon light on

Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.

1992 GMC Sonoma - 4.3l cannot start after stall and knocking.

Sounds like an engine sensor, EGR valve or O2 sensor has failed. First thing to do is to look at the engine trouble codes to pin down the failure. You can usually borrow an OBD1 code checker from your local parts store.

2002 Dodge Caravan is very hard to start

this sounds like the fuel pressure check valve in the fuel pump has failed, have a fuel pressure leak-down test run, the system should hold pressure noted at engine shutdown for 24 hours with o more than 5 PSI drop, if it leaks down u get air in the system and the symptom's u have described.

Temp guage barely moves and runs rough just off idle

Try a full tune up.. get Bosch platnium+4 spark plugs and Acel wires, do the fuel filter and air filter(i suggest K&N) buy some fuel injector cleaner or use Marvel Mystery oil. The ECU could e gone but hard to diagnose if the car needs a tune up.
