1. looks like someone had an aftermarket temp gauge that plugged into that sensor. its defn. not the stock one.

2. looks like the 'stock' EGR/charcol canister system is still hooked up. nix that shit. plug and get rid of any unnecessary vacuum lines. could be leaky stock BOV. could be after MAF leak. dirty IACV. incorrect idle adjustment.

3. could be a anything; worn tie rods, coilover springs twisting in perch, worn steering rack bushings..ect. my first guess would be bad TC rod bushings.
