I finish the swap to my FC. She started and running idle at 750-800rpm range perfectly fine but like 10min later it'll would just die. Or it i take it for like a long drive i cant let go the throttle or she'll just die and i have to wait a while till she'll start up again. I get series for back firing from time to time.. so im not sure if the injectors are leaky or timing issues is on hand here.

you need to check everything, your connections, TPS, and your timing

my first thought was tps or temp sensor, because the engine got pretty warm after driving more than just around the block, and timing was my main concern because it make it weird noise when im passin 4k or what not
