so let me start off my saying i have been fighting this issue for over the period of about 3 months so far. heres a short video to see if you guys have ran into anything like this. im battling this first start issue still. in this video you will hear when i hold the gas pedal steady the rpms will hunt, almost like its either cutting fuel or spark. this does this at any rpm. its not the tps or map sensor. any ideas i would love please! also found out that if i unplug the coolant temp sensor, the fans will come on. is this right? as stated the car will not start on first start ever. it will just crank and crank with no spit or spudder. spray some brake cleaner through the uim and it will spudder and start. if you shut the vehicle off before it has a chance to warm up say 40 seconds you will have to spray some brake cleaner in it again to start. otherwise let if warm up for say over 40seconds and it will start back up on its own. PLEASE GUYS HELP ME OUT IM RUNNING OUT OF ALL IDEAS.
so far i have replaced and rechecked
-engine harness( this is a jdm)
-front main harness
-all sloenoids are removed execpt the fuel regulator is plugged up, i have the fpr running straight to a vaccum port.
-spark plugs and wires
-adjusted tps 3 times just to be sure
im running the factory ecu and compression is at about 90psi
