Just got alot of stuff done, as shown in the sig. But i am sorta hesitating or missing in higher rpms...the thing is, i still have my stock injectors that i believe have 150k+ miles. do you think fuel regulator and some 30#s could fix it?

 

9 times out of 10, a skip/hesitation is the result of an ignition issue. I see you did plugs and wires...how recent? Is it the original optispark?

The only true way to tell what condition your injectors are in is to pull them and have them checked on an ANSU machine. That way the spray pattern and volume can be verified as well as cleaned beyond anything you can pour into the gas tank.

 

I would also recommend taking a look at your ignition coil. Typically a miss up top is due to a bad coil.

 

new wires, plugs, and opti. just went in w/ the rebuiold and ncoils want much before that(msd)
