    Progress Thread 7991LXnSHO’s- bug deflector damage.

    After being here and owning my current Mustang for 10 years, I realize it would have been good to have a slow progress thread to keep track of what was done and ideas that need done.

    I noticed my tps and other sensors like iac and others are giving a 12 volts read on my multimeter with key-on instead of the usual 5 volts it goes as high as 18.5 volts with car on!
