MR2 2AR-FXE Cold Start
Stock exhaust aside from frankenstien motorworks header. the first few clicks of the relay before starting up is probably the starter acting weird, i have to turn the key a few times for it to start on some days.
The rattle in the first few seconds of running is because the haltech needs a second or 2 to synchronize the VVTi cams, so it "kicks in" as the rest position is not lined up with cold start timing. previous night was -12 C and currently its -6 C.
