Guys, I could really use some help with my car's new warm start trouble. Seems to start better when car's cold, but when it's warm, it starts "technically", but for the first few seconds the engine is either being choked (not enough gas getting in) or maybe flooded?

Upon starting, the engine always turns right away, but then seems to struggle to come to life - rpm's are like around 200-400 initially, then seconds later the engine comes to life and idles perfectly. No idle problems or stalling whatsoever once car is started. Goes WOT perfectly as well as drives smooth around town.

Last thing, the problem began after I had cams and 750cc injectors installed, followed by a custom dyno tune...


Any thoughts? Do you think it's the injectors are not properly scaled, too rich or lean at idle, or need plugs changed (have never been changed)? Car has 14k miles on it and mods are below in sig... Thanks, guys

 

To rich at start up due to the tuner trying to make the car idle after the cams...mine does the same thing.

 

what was used to tuner your car... tactrix cable, ecu flash etc...

 

Same issue with mine. I just put in GSC 280s, 780 injectors and 50trim. I am getting tuned over the email, so I am sure this problem will be fixed soon after a few more logs and maps.

 

assuming it was tuned on ECUflash, is there a simple fix like taking out some fuel at idle? I know my idle was set to like 850rpm, don't know if that matters...
