Problems with TPI spark
Hello everybody
Iroc was rebuild and i drive it for a year. All this time i have problems with spark.

What problem is:
1. If In idling position make 2500 turnover for 1 minute - exhaust manifolds (stock iron) become red and then white. In drive position no problems with color of exhaust manifolds
2. When i push gas pedal in idling exhaust pipe start to shot fire. (ignition set according to instructions)
Specs:
TPI with top intake Camaro 1991, lower intake with heads Vette 1987
ECM Camaro 1991 (stock)
Timing set in stock position
EGR delete
I realy do not understand where problem is? TPS? Oxygen sensor? MAP? Knock sensor? ((( Please help.
By the way, i have another problem:
When i stop after driving, the gasoline starts to swell in the tank. The fuel gauge also jumps. At the same time, the engine XX begins to float up and down. In this case, the car may stall. When the fuel tank is full, this is not a problem so often.
