4 brand new NKG ZFR4F-11 plugs
new 10mm tripple strand plug wires
new 193* thermostat
new belts
new hoses

one thing to note, the idle surges when its cold and when moving at high speeds out of gear when idling. but when it comes to a stop it calms down to 650rpm's

I cleaned the IACV with brake cleaner, it helped with the surging after it was warm and moving at freeway speeds.

I need to clean the FITV and rebuild it. every morning the car goes to 1500-2k and surges until it warms up. then its fine...

Im wondering if one of these is causing a VAC leak when on the freeway...
