- Apexi Short ram intake
- Perrin turbo inlet tube
- APS SR40 turbo
- APS up pipe
- HKS down pipe
- Greddy RS BOV (recirculated)

Only starts like this on a cold start. Any tips?

  • get it tuned. im pretty sure its really off. specially with all the mods you have. like getalife04 said. it sounds like a A/F ratio problem and your engine is retarding the gas ALOT. cuz it sounds like knocking when ur starting it

  • Normal lol or get a new battery. Stock one isn't the best check your water levels in the battery top it off with distilled water only, start it up run :)

  • i hate the sound of those things

  • That wasn't even that hard of starting

  • I would have to say that you definately have an air fuel mixture issue. I would check everything and make sure that nothing is leaking along your intake and make sure that you don't have a vaccum leak anywhere. If it comes down to it take it to the dealer and have them hook it up to their computer they can tell you with their computer whats up. But with your mods I don't know if that will effect the results or not. But check that stuff first.
