22 - TPS voltage low
33 - MAP sensor, signal voltage high, low vacuum
42 - Ignition control circuit, short or grounded
48 - MAF sensor circuit...plug your maf in....can see that in the vid
63 - Bank 2 (right) O2 sensor, open circuit
83 - (M6) Reverse inhibit system
85 - Transmission TCC stuck "on"


are you sure nothing else is disconected or any damaged wiring?

the MAF is unplugged because one of the wires on it is broke off too close to plug in having to buy a new pigtail for it..and yeah thats all thats unplugged on the car..oh its an auto car forgot to mention

check all of the wiring around the (guessing) pass side exhaust...make sure nothing is damaged...thats alot of codes....I tend to look for what all of them have in common to start with

there is the ignition system wiring diagram...verify wire color and pin location and repair as needed

Look out for fried wiring...i had just the opposite....my driver side header cooked some wires....

The people that did my header install were idiots...

I learned after that....DO IT YOURSELF!!!
