STOP USING IT NOW

You need to educate yourself--study OBD 2
Vehicle Systems

We have had check lights for 35 years,no reason
to not know about them or what to do

You do not use any vehicle with a check light or
any dash lights on,they are telling you the vehicle
has system faults, that need to be diagnosed & find
a problem to repair

It shakes,it smells-- but you keep using it,will get
very expensive, if you don't change your ways, when
it comes to motor vehicles

Get it to a dealer or the best local shop you can find

The BEST Shop-- not some highway chain store-- where
you sit for 5 hours & they do little

That is strange. Do not rule out the possibility that you have a leak somewhere in the vehical. I would check this out immediately, or it is going to cost more in the long run. Check the oil pan and the ground where you park your vehical.

Your EGR valve...Hope this helps.

you have to have a computer to reset the chang oil light

vacuum leak, bad plug wire or a bad sensor

p0128 engine coolant thermostat below operating temp. Possible low on antifreeze. not plugged in, possible chaffed wires.

P0106 pertains to the throttle body. most cases involve cleaning the throttle body

try turning up the idle ajustment screw also have alternator checked, another solution would be to have your car tuned up weak spark from your coil worn plugs wires etc. not enough power is being produced

Check your transmission fluid level with the engine running and your shifter in Park. When was the last time you had your fluid and filter changed? Could be a plugged filter.
