checked the codes there are 8 of them po606 po238 po237 po123 po118 po113 po112 po236 i checked the book po606 is ecm failure but could it be something else before i buy a new computer ?

 

The first thing I would do is unhook the batteries for 20 minutes and ground out the system by pushing the brake petal/turning the key while they are unhooked. Reconnect them after that.

While they are unhooked, I would check my grounds and the connection to the ECM, look for corrosion and loose wires. Feel the main ground, see if it feels abnormally hard, there may be hidden corrison.

I did not check all of the codes, so there may be something else...

Hope for the best...
