first i hope i put this in the right area i changed the plugs rotor distributor and wires on my 94 s10 vortec v6 the plugs were super bad . well now i go to accelerate and it seems like i'm not accelerating . no matter were i put the peddle then it feels like i have a slight hesitation/ minor bucking .
could it be throttle position sensor fuel filter or i was told might also be coil pack ?
to try to fix it i disconnected battery for over a hour now it runs a little better still has hesitation but not as bad.
before the plug change i was getting service engine soon light coming on ever so often after plug change i reset computer after battery reset and driving it around for a bit no light yet.
i also noticed this the little plastic thing on end of this hose i think used to have a cap iv got some delayed shifting this comes up next to trans fill tube could this be part of my problem?

also thinking you need an injector harness too... These things should be part of a tune up, seriously they are not good. 8 bucks. Ive been screwed by this darned harness a couple times.

look at the cat conv. once they get cloged they cant send air throu the pipe pull your oxy.sensor from ths exaust it will be a little noisy but you shoud see some improvment or just replace it all together

it should be connected to a plastic clip on the frame and the plug in should be just beyond that about 6 to 8inches was the cat removed and replaced with a straight pipe?

No idea what the part number was. Just ask for the injector harness for your engine, it should be a white head with an oval shaped rubber insert in it, and there is 2 wires, red and blue, its about a foot long. You remove the upper intake to get at it. Dont try to remove the gromet the wires get outside the engine through, just cut them off and push through then solder back on. Let me know what the condition of the old one was though as this is my personal least favorite part on these trucks so far....

what codes have you been getting? You can check them by using a paper clip to jump the terminals ( i think its a and b but its the two upper right plugs on your OBD1 ) then you count the blinks
EXE: blink pause blink blink would be code 12
you jump the two terminals then turn the ignition to on
It will blink code 12 three times then it will move on to the next ones
If you have a haynes manual it should have more info on this in chapter 6
good luck
