Hi guys, I am experiencing some warm start problem with my EVO SST. It's either a hit or a miss when the engine is warm. So far there are no problems with cold start in the morning.

Some background, my X is still on stock injectors and fuel pump. My plugs are fairly new (about 3 months old) and they looks fine when I took them out last week to check.

What I noticed was when the car do start, I had to give it some throttle to prevent it from stalling. Otherwise the car drive well without any issue.

Any suggestions on what to check next?

 

Letting us know your mods and if you are tuned would be a massive help.

If your car is stock, go see the dealer.

 

Yeah, so far I have an AEM intake, GrimSpeed 3 port EBCS, ETS intercooler kit and Blitz cat back exhaust.
