when i first start up my car it bogs around 5,000rpms until it warms up then it goes away,would anyone know what that is?

i think it might be my fuel injectors but im not sure.

5k?? do you mean 500?? you might have some idle air control problem...iac valve cause a air leak at cold start up to let your car heat up then once heats up iac shuts off...fuel can't really be the problem...to test if its fuel...just mash it full throttle..if it ups n goes its not fuel related (if its fuel the car should spudder do to the fact ecu reading tps is fully open so its dumping as much fuel as it can)...n worst is worst low compression do a compression test...
