Mcx apex hard to start? Need help

[viperbusa]

Having trouble starting my apex when cold. Have to hold the throttle open just slightly or it dies. Acts like it is flooded if open throttle all the way. After holding it like this a few minutes it will idle on its own. When warmed up starts and runs fine.

Interesting, my MCX turbo Phazer does the same thing.

Do you have an AFR-meter?

Stock plugs gapped to 0.018" or 0.45cm.

Don't have afr on this one. Shouldn't it be running stock injectors when at idel? Or can I map it to lean out at idel?

I had the same on mine, was a faulty mcx ecu reading boost at startup when cold.

What did you do to fix the ECu

 

[MRFUSION]

Did you just recently install the turbo or did this problem just start?

changed the ecu, try disconnect yours.
