502 Mag Hi-idle after start
Hi,
Does anyone have a 502 MPI Magnum that would run about 1500rpms when first started? After it heats up and runs a bit it idles ok. I was thinking there was an isse with the IAC. I hear a "shisshing" noise while this is going on. I'm hoping it's not metal contact but no oil loss or anything.
Thanx
