My 95 2500 (K series, 4WD 350) is having problems that I think may be injectors and if it is I'm going to buy the holley TBI unit but I want to make sure before I drop the money on it. The truck is all stock other than a K&N and full exhaust and has just over 120k on her.
First let me state that I did the fuel pump and filter in July.
Now the problem is that it stumbles when starting from a stop, once I get going I can get on it all I want and there are no problems but starting out from a stop if I go anything above 10% throttle the truck stumbles so bad that it dies. I am so skeptical because I have already tried swapping injectors with some I had laying around and it didn't help at all, if anything it hurt. I cleaned the original injectors as well as I could (just by taking them out and cleaning the screen) and put them back in and that seemed to help a little, after that I sea foamed the motor and didn't really notice much of a difference but I only drove it around the block (did that today). The PCM is throwing a lean code every now and then but it appears to be random and has done that since I owned it, when I hook up my snap-on scanner and watch the data feed I don't notice anything out of the ordinary. It does take a few seconds of cranking to get it to start but it has done that since I got it as well. Thanks in advance.
