hey guys, so a couple weeks ago, i had a slight misfire on my car that didnt show any CELs. i took it to my mechanic and we suspected dirty injectors since i just did a valve adjustment / spark plugs. cleaned the injectors, throttle body, piston, intake. misfire went away. but suddenly i started to have a weird problem. when starting the car, theres like a delay or hastened start. i took a video of when this happened. its very unusual because it starts right up when its cold, but after driving it and starting it, it does it. i replaced air filter, checked battery / alternator (checked out to be fine). so i have no clue what it is. maybe starter? my starter was going bad, but it never had this issue. it has to be from the fix from the misfire. it never did this before.

 

Reset your ECU (search on here) and try again. You can check your long-term fuel trims also just in case but you can just jump to the ECU reset to zero them out.

If the issue persists, keep in mind that it might not be fueling related then and a slow start/crank when hot does sound like a potentially tired/bad starter.

 

already tried resetting ecu. didnt solve the issue. my starter was already bad, making the grinding sound every so often. i dont suspect the starter bc this issue started out of nowhere

 

Mine has been doing this for 10+ years. It acts like the battery is low when warm and barely starts, but ALWAYS eventually starts. I'm starting to suspect maybe a bad ground, but I've been through those a few times and even replaced the engine wiring harness, starter, and battery (Multiple batteries) for good measure. No luck so far.
