1986 vette trouble
getting two codes 23 and 32 just replaced the manifold air temperature sensor 23 and now it says it is open itfluctuates between-40and 200 degrees celciusis this correct? Since I changed this sensor now I am gettin a code 32 it seems like whenever I replace one thing another one is ready. I need some advice car doesn't run bad until I get on it/.

Air temp should be what outside air temp is on cold starts and will warm up as engine tempdoes. It sounds like the plug is not plugged in and it is a fun one to get to. Code 32 is EGR and more than likely the EGR temp switch in the tube coming off right exhaust manifold by the distributor is bad or the vacuum solenoid that controls vacuum to EGR valve. [8D]

Sorenson is a cheap brand. I suggest you try either Carquest or someone who handles A/C Delco parts. First, check and make sure you hav vacuum on the EGR vacuum solenoid. Follow the vacuum line off you EGR valve to a solenoid bolted on the thermostat housing and check the other line on the solenoid at idle to see if you have vacuum. [8D]

I would leave the mat sensor right where it is under the manifold, and relocate it to the air inlet ahead of the mas sensor The original position gets the mat heat saturated, and the relocated sensor is in plastic, which is almost not influencing the mat output to the computer.

I have thought about removing the sensor with the kit, butu I heard it does nothing and the horsepower claims is false and that it might hurt performance....Just heard from others though so, I am asking what are the advantages/disadvantages of it?
