2001 Chevy Blazer. Service engine soon light on. Check comp and replaced Temp. sender. Light came back on and it says it's the thermostat temp. sensor. Any idea where this is located?


The temperature sensor is located on the intake manifold by the thermostat housing. Check the wire leads first and if that's good, replace the sensor and thermostat. The 4.3 was programed by the factory to run it's best at 190'", if it runs too cold. The mil light comes on indicating a temperature sensor failure.

MPG excessive .10mpg 2001 Chevy silverado auto. 4.8 eng.I have new air filter fuel filter fuel pump OE tires,new oil 10w/30 pplugs look god as do the wires .No OBD lights truck runs great why the low MPG...


Usually horrible fuel economy comes from bad oxygen sensors, especially if the engine runs well. Oxygen sensors tell the engine how much fuel to add to the air it's taking in based on how much oxygen is making it out the exhaust. When they go bad, typically the computer's telling the injectors to dump tons of fuel into the engine, because it thinks there's too much oxygen making it through, meaning a lean mixture. They're normally good for about 100,000 miles on modern GM vehicles. and are easy to replace. You have 2 of them that matter for this purpose; one on each y-pipe, between the exhaust manifold and the junction of the "Y" before the catalytic converter. You will need to replace both. They look like a spark plug with a bundle of 4 wires to lead to the engine compartment. If you lay down and slide under the truck right behind the front wheels and look up, you should be staring right at the sensor. The best method of replacing is with a special socket that you can get at any parts store that allows the wires to exit the side of the socket. You do have a total of 4 of these sensors; 2 in front of the catalytic converter in the y-pipes, and 2 after the cat. The two after have no effect on the mixture; they are only for the emissions controls. Finally, 90% of the time, O2 sensors are responsible for poor fuel economy and poor emissions.

There are two knock sensors on your engine, and they are underneath the intake manifold. You will have to remove the intake to get to the sensors.

IDLE PROBLEM


Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
