No im not happy that i spent tha money.. When i bought the truck i had a new dual exhaust with new 02 sensors installed..

HAS no exhaust leaks b4 or after 02 sensors.. has no convertor on either...

Spend the money on that cable and the free software and learn how to do a data capture then look at it and fix what is wrong.

can you verify what type of egr system you have and double check to make sure you have the correct egr valve for it.

all the parts that i have replaced came from the gm dealer.. i provided them the vin number and they gave me all the parts......

far as the data capture.. the shop did that and all the sensors and everything was working and in order they said...

the one thing they did tell me was when they had the tank dropped the strainer was clogged with rust. they thoughly cleaned out the fuel tank before re-installing.. do u think that maybe the filter and line goin to tbi could be clogge???????

 

[SunlitComet]

possible. have you actually done a key on engine off reading of any codes by enabling the diagnostic mode?

 

[cburns002]

@sunlitcomet... can u explain how and what to do??

 

[SunlitComet]

on the diagnostic connector below dash look at the top row of terminals and the right end the last two wires should be white/black and black white. these wires are right next to each other not a few wires apart. short the two together and turn key to on but do not start. the check engine light will start to flash. 1 flash, short pause, 2 flashes then a long pause. that means 12. you will see it flash the number 3 times. if you have fault codes they will each flash 3 times, if you have no recorded faults it will continue to flash 12 continuously.

@sunlitcomet. ok i done the key off code and first code was 12 then it flashes 3 quick flashes?? would that mean a "code 33" any ideas what that code is?
