hey everybody let me start by saying my car is a jdm import st205wrc with the 3s-gte engine
i live in ireland and always run 99ron fuel
my problem is a bit of a odd one to me im getting a miss/hesitation around 3k rpm but not when cold or hot
but when its been parked for around ten min after driven and then go driven again and its only there a few
min and goes away again
iv put in a new fuel pump, dizzy cap, rotar arm, leads, fuel filter all from Mr T ngk plugs no7 iriduim and platinum
and checked the timing and all vac pipes
has anyone here even come across this before my only other option after this is take it to Ttec

Only thing I can think of is perhaps you need to replace the coolant temp sensor.

re-check spark plugs and wires. check for air leaks after the turbo. when this happens, see what the OEM boost gauge is showing. probably AFM is malfunctioning. you can do voltage test on the AFM (if you`re not using map sensor).
i`m not sure, but maybe fuel filter its a good idea to replace it anyway

ok so where exactly is the coolant leval sensor

"AFM is malfunctioning. you can do voltage test on the AFM (if you`re not using map sensor).

st205 run map sensor from factory and i have a new fuel filter in already

coolant temp sensor...its located on the coolant neck on the engine
