It should have the W code engine. If you look at the top of the engine it should have an air filter mounted at the front of the engine compartment with an intake tube running to the engine. If it were a TBI engine it would have a standard air cleaner on top of the engine. I believe GM quit using the TBI in favor of the SCPI in 96. Hope this helps.

94 tbi starts but dies unless u pump the gas it runs rough


This could be a whole range of problems from lack of fire to engine to a bad fuel pump or pressure regulator in the TBI but if all of that is good then check the Cat. converter to make sure it is not plugged or the muffler. As I have 1994 Chev Silverado myself I know you can pull the 02 sensor out ahead of the cat. and it should run better not well but better. It will relieve the back pressure to the engine.

Location of thermastat on 2000 chev blazer


Hi Bill, Open the hood and follow the top radiator hose to where it is connected to the engine. At that point you will see a domed housing which is the thermostat housing. regards John

WHO KNOWS ABOUT THE 1999 CHEV. ENGINE 4 CYL.? IS IT A GOOD ENGINE? I AM THINKING ABOUT BUYING A 99 S-10 WITH THAT ENGINE IN IT.


I have owned a 1984 S10 blazer since new,
some 28 years & I would never buy that with
a 4 cylinder

I have a 2.8 v6, the only 6 cyl I have ever owned,
& it won't get out of it's own way. People have to wait
at every light,it take a 1/4 mile to get to 40 mph,can
you imagine almost 5000 lbs & a 4 cyl
