LT1-LT4 Modifications - LT1 surging/hesitating when Hot

Hey guys im trying to be patient but for the life of me googling and looking on other forums i cant get a straight answer on why my LT1 starts to surge and hesitate when hot(220) in the middle. It runs fine until the needle hits the middle of the gauge. It also backfires at around 5000rpms. Can someone throw out some ideas what it could be? there is alittle oil leaking on the opti but i cant convince myself that thats the problem. what could it be? MAF, O2 sensors, intake leak, opti, air fuel ratio what? It doesnt seem to pickup as fast when its hot. Please help. lol :bomb:

If it's failing when it's hot, might be your ICM.

Also, 93 runs speed density. No MAF.

Mine would do the same with bad o2 sensors you may want to check into that first , opti could also be the problem if the oil has worked its way in there its going to go out .

Thats funny because mine has a MAF and its a 93. My manuel even says 93 camaro lol.

Pics or it didn't happen. Possible it had a 94 drivetrain put in it, but 93s don't have a MAF at stock.

Well i dont have a car fax and ive had the car for not too long now so i dont know the cars past.

Drivetrain swap wouldn't be on a carfax. You can check the vin number on a decoder to find out the year of the vehicle.
