Is it posibile that I take computer out from car, like in old time when car have only few wires?
I know that problem on blazer we can get because of some bad sensors. I dont want them!

 

technically but you will probably need a new engine and transmision. years ago i had a 95 s10 pick up truck, i put a v8 engine and trans out of a 82 chevy van, and it had minimal wires going to the engine, just powering the alternator, distributor, and coil. and as you can guess never had one issue with that truck. always started and drove

 

I have feeling that they use this all this just to sell more and that we visit service every 30 days..I realy like old style car...
