I have a 96 lt1 in my 91 z28. the problem i'm having is when i give it gas it chokes. like its getting to much air or not enough air or it could be the gas don't know. i changed the maf sensor thinking that was the problem but it stll does it. i talked to a guy at work and he said it could be the throttle position sensor. i'm thinking about changing it but i want to be sure thats the problem and not get something i don't need. any help please thanks. i haven't checked the codes becuase i'm not finished with the wireing.

 

Finish the wiring.

 

the only thing i might have left is check engine light and speedo. all the main wiring ground ,power ,fuel ingection etc is done.
