Why does the engine stall a couple times when i first start my toyota t100 2.7

Hi there: It could be a number things fuel injectors that are wearing out also vacuum leaks that after vehicle warms up they go away etc.. I would suggest to have a ASE certified repair station to look at it. We here at Ultimate Performance would be more than happy to look at it for you. Please feel free to contact us at your convenience. Sincerely Ultimate Performance Team
