Evo 8 340 Mr
Apexi fc ecu

When I start my car in the morning when cold I let it warm up a little bit then as I'm driving down the road it seems to be struggling, as in it like goes and stops like it hesitates to go anyone had this problem or know what it could be? Any info would be much appreciated 馃憤馃徎

I haven't noticed it when it's warm it's only on first start up and no it's not abrupt just a slight loss feels as if it's dropping 400 rpm or so then goes back up and does it a few times also my tickover sometimes does what it wants and take a while for the choke to engage

I'd be tempted to change the coolant temp sensor that feeds the ecu first.

After that, if it runs fine hot it may need extra warmup enrichment, even +5% can make a massive difference.
