ok just got hotrod cams installed and i was planing on getting it dynoed at the shop but thier dyno software wasnt up to date so i had brenspeed send a tune. the shop told me i could drive it home with out the tune (as did brenspeed), its less then 2 miles, so i get about half way and it dies. i restart and it seems as if my throttle doesnt work cause ill floor it and get about 100rpm increase. so i had to leave it overnight in a parking lot till the tune came in. i go back today load the new tune and i get the same problem. the car will idle at about 1100 for 15 secs jump to 2200 on its own and then stall. im getting Po123, Po223, Po2104, Po2110 codes. i think the 123 and 223 are throttle position sensor codes. WTF? is it the tune or did the shop not plug something back in? please help.

P0123 Throttle/Pedal Position Sensor/Switch "A" Circuit High
P0223 Throttle/Pedal Position Sensor/Switch "B" Circuit High
P2104 Throttle Actuator Control System - Forced Idle
P2110 Throttle Actuator Control System - Forced Limited RPM

this is what i just found on google. what would cause this?

thats what im thinking but looking at the codes it also looks like the car is in "Oh **** somethings wrong" mode

I just got the Brenspeed 91 tune for my FRPP Hot Rod cams that I installed last week. The car is a monster. Sounds like you need to comb over your engine and make sure all connectors have been reconnected. Hopefully your engine didn't jump time during the cam install. I hope they used the required spring compressor and timing chain wedge. I know some people get away without it but Im just saying. I highly doubt the it's in the Brenspeed tune.

Check the tune... maybe they set the RPM's low... try returning to stock tune... disconnect battery then reload brenspeed tune and check the idle and RPM cutoff... they coulda screwed it up

aaaaaaaaaaaaaaaahhhhhhhh............for the sake of the search feature and any forums members running into my issue i will not try and delete ths thread eventhough it makes me look like an ***. i went to go unhook the battery and noticed the throttle body sensor pulg was disconnected. reconected it and everything is good again. so for any one searching the engine codes above in the future CHECK YOUR THOTTLE BODY SENSOR AND MAKE SURE THE DYNO SHOP DIDNT LEAVE IT UNPLUGGED!!!!! thanks for everyones input, its why i can here first before calling the shop or a tow truck.

Jeez. I'd call the shop and let them know so that they don't make that mistake again for anyone else.

if it was unplugged u would have had that problem as soon as u tried to leave, they prly just didnt plug it in all the way, and it vibrated loose
