hey guys. this is kind of long but i really need some help so please read.
i just purchased a 05 silverado a couple weeks ago. a few days after i bought it, it started smoking only when sitting in gear. as soon as i would hit the gas it would stop. when it would do it, it would feel like its running rough then it would smoke white. as soon as i take off from the light it starts running smooth again and stops smoking. its very random. sometimes it goes days without doing it. i also get a very strong smell of diesel when it starts doing it.
here is what i have done so far.
i took it to the chevy dealership and had them flash it to stock. (i wanted to make sure it didn't have a bad tune or something)
i also had them run a injector balance test. the guy told me all the injectors were out of range except cyl 2 and 7. he said anything about 1.8 +or- was bad???????
they were reading anywhere between 2 all the way up to 9. this was after he flashed it back to stock and after driving it about 200 miles. i don't remember what was +or- or which injectors were doing what.
it definitely had a tune on it because the drivablity was completely different after they flashed it back to stock
so i bought an edge juice with attitude tuner so i could try to do the injector balance test myself.
i ran an injector blanace test with it and here are the results
injector 1- 9.3
injector 2- 0.3
injector 3- -0.7
injector 4- -1.5
injector 5- -3.3
injector 6- -3.1
injector 7- -0.1
injector 8- -0.9
i also had 4 codes but not CEL
P0303- cyl 3 misfire
P0401- egr flow insufficient
P0404- egr control circuit performance
P1229- injector 3 output
this was all done after driving it for only about 10 mins on power level one
