well installed some new injectors today and the truck is running lean as hell long fuel trims +25 and short fuel trims +18 +15 bouncing back and forth, what have i done wrong?? I've looked at all injectors and made sure there all pluged in properly no leaks.

 

I assume these are larger injectors. If anything, I'd assume them to run rich if they were were plugged in without a tune.

TTT for you.

 

your pcm needs to be retuned for the larger injectors.

 

there not larger injectors they came out of a 2003 gmc truck. they were his stock injectors and he put on a radix so i bought his old injectors thanks.

 

taking from an 03 and putting on an 01 may not be the same type of injector.
I know on these trucks on stuff is changed every 2 years, it is 99-00 then 01-02 then 03-04 even the 05 is slightly different then the 04

 

well i will pull them in the morning and see if there the same part #. the truck is very hard to start and is running way way lean. when you floor it the truck just boggs down like it cant get any fuel. maybe there just clogged from sitting to long??

 

quit messing with it Kevin

 

i told you daniel you broke the damn things messing with them......

 

I had NOTHING to do with it, I plead the fifth and all that jazz...Zed
