I recently installed an intake manifold spacer in my car, as well as 2 new gaskets on both sides of the spacer. The spacer restricts a small amount of heat from the lower part of the engine to transfer to the intake manifold. After installation I had my CEL come on. Auto zone and O’Reilly ran codes and they were P01123- throttle position sensor/switch A circuit high input, P0222-throttle position sensoror pedal position sensor/switch B circut low input.

I sought help from some forums members at a certain website, and they suggested I get an OBD2 reader and an app on my phone to read if I was getting WOT from the TPS/Electronic throttle control. I did and I do get a full WOT when flooring it, which should mean the TPS/ETC is fine. I then used the reader and the app to pull codes from my ECU, and I got P0113-intake air temp circuit high input, P0106-manifold absolute pressure/barometric pressure circuit range/performance problem, and finally P2228-barometric pressure circuit low.

I have tried resetting the ECU a number of times. I have ensure all sensors are plugged in. I have ensured there are no loose wires or nicks or cuts in the wires. I’m at a loss as to what to try next. This is sort of a oddball car to get help on because, other than a dealership, there’s just not many specialists out there for them. Thank you for any information you may be able to provide.

My car is stuck in 3rd gear and the CEL is on. Took the car to the local Auto Zone and had them check the codes. The code that came was P0750 which after doing some research points to a bad shift solenoid A. What would be easier or the best way to fix this? To either replace the solenoid or to replace the entire valve body? Also I wouldn’t know which solenoid to replace because I haven’t found a good diagram to go by.

Mother in law is 13k past due on oil change. Pulled dip stick and the only oil present was the oil burnt to the stick. Popped the cap and can see its just burned up bad. After a couple of years working in a GM service department I know how bad and costly this could be. Any way to flush out some of the burnt oil and sludge without a complete teardown?

Can you please tell me the name of the part pictured with the hole in it. I am unable to find this piece online and I don’t know what part name I should be looking for.
