Okay so i bought this S10 Blazer in June for 3500 . At the time it was a nice running ride. Drove it to kansas and back home to texas ran fine till i got 2 block from the house. Then it started just and almost stalling out. So i replaced the spark plugs with oem ac delco's new plug wires cap rotar. I also replaced the tps idle speed controll motor, air filter, fuel filter ,new oil ,iat sensor . still didnt run right so i took it into the shop , they said egr valve cloged had it cleand and put back on ran fine for 3 weeks then it started the slight rough idle . So i took it back into the shop . the did some test and found that i needed a nem mfi injecter set . had that done . still running poorly oh and i forgot to mention it was black smoking and loose gas mileage maybe if im lucky i get 180 to a tank . so again this time i take it to Chevy they said you need a new computer put in . SOOOOOO i had that done and what yeah your right still poor gas milage black smoking smelling rich . any i deas i vote for selling my problem to some one else unless i can get to the bottom of it for not much more money . by the way it is a

Has it set any codes in it? It's hard to say without being thier to look at the data and stuff like that.

 

Right after i put the computer in it set a p0113 IAT sensor but i replaced that sensor and had the code reset havent checked it yet was told to drive it around for a while and then take it back to be check for codes again .. will update post tomarrow when i have the codes checked again .. also i have been told that it takes 50 -100 miles once the computer has been replaced for all sensors to resync and adjust . is that ture . if so then im just prematurely over reacting .
