    Sometimes I seriously hate this car. Codes inside.

    Car is starting its reduced engine power bull again. This time 30 miles from home. I'm almost home now but I got hungry and luckily my father works nights and is a police officer so he went to get me food lol. Anyway, dad also has the keys to a friends shop and I checked the codes to see if I could clear them long enough to make it home. No dice. Codes are P1516 manufacturer controlled vehicle speed, idle control, and aux input. (whatever that means) P0220 and P0120 throttle peddle position sensor switch A and B malfunction. I'm on my phone. This sucks.

    Your throttle body went bad. I had the same codes last month. Left me stranded on the side of the road and I had to call a tow.

    Luckily the dealer replaced my TB under warranty even with it being bolted to a maggie

    Then they even ground down the casting on the TB so it would fit under the hood

    You might want to disconnect the TAC module if it's intermittent 1516 code. A friend's car had the plug just resting there and no plugged in!

    The TAC module is next to the fuse box but between the engine and fuse box under the hood.

    My A/C died on the way home from V-Day III - The DIC-head displays "Service AC". This car is wearing me out with all the trips to the dealer. My first GM car may be my last.

    cars are not supposed to have any problems. Sell them and buy a Prius. They're made by Toyota so you know they're perfect.

    I was thinking this before I even finished reading your first post!

    Broken stuff is just an opportunity for upgrading...

    Do you have Corvette FRCs? If so I would guess they cut through one of the wires. Its happened to more than one person on here.


    I currently get the "Service Vehicle Soon" message every time I fire up since my Oil Pressure Sensor is finally caput and gives a --- reading.
