Any TBI knowledgeable people in the Indianapolis area

[all87s]

I just bought an 87 monte carlo luxury sport. It originally had a 4.3TBI and was swapped out to a jasper 5.7TBI. It will start and run, but not smoothly. Ive had this car since last season and would really like to get it up to daily driver status. I began trouble shooting but am at a knowledge loss that has brought me to a stand still. The engine light will come on after a few minutes and if I remember correctly it is a o2 sensor and one other code. I have swapped computers to the correct one for the 5.7. The swap was not a professional swap, so I feel like there might be some type of wiring issue. If anyone is in the indy area and would be willing to come out to educate and help me, I would be more than willing to compensate them for their time, wether you want my help or prefer to work solo. I bought this after I sold my aerocoupe and have been going through monte withdrawls lol. Thanks in advance everyone. FYI this is my first post. I am more of a lurker for knowledge than a poster but have been a long time browser of this site. Alot of good info here

Wish I were closer u sounds like a wiring issue indeed I did a tbi swap in my 84 and it's not a 100 percent perfect wiring swap from the 4.3 to the 5.7.....I'd be curious to know the code numbers u got.....the tbi 5.7 is a very reliable motor
