Why is the engine on 92 Chevy truck flooding and bogging down?

Answer 1

i have a model similar to your's. there is little you can do without getting your hands dirty and going into the engine, which most people dont like to do that, simple things you can do is; fuel injector cleaner (read label for tank size the bottle is designed for) buy a bigger air filter, new spark plugs, for this model i would say autolite, whichever kind as the biggest end to get the biggest spark. if you dont want to buy new spark plugs then at least clean your old ones. very cheap ways to do a lot. what i ended up doing to my truck is clean the fuel injectors out with paper clip, gave me a lot more power. fuel injector cleaner is more of a preventative but it will give you 10-15 more horsepower back. replacing your belt will probably reduce power, but is better for the engine. new air filter and at least cleaning your old spark plugs is a must.

A faulty engine coolant temp sensor (the one next to the thermostat housing) can also cause that condition.
