Take off your ovcp and look inside the throttle body see if any drips out of injectors. For best results send your injectors out for cleaning and testing rock auto does it as well as other places.Also fuel gage should be installed at the back of tb where the set screw is.Fuel pressure should stay at 36-38 and never drop regardless of rpms.If it does? Your fuel filters are clogged most likely from rusty tank or your fuel pump is weak possible fpr. But most likely clogged fuel filters. In that case l suggest cleaning the fuel tank new filters and cleaning all the lines top hat before you install your new or tested injectors.Little bid of work but worth it!
Other things to do is check your timing is set at 10deg and test your vacum advance.New plugs wires cap rotor and ignition coil.
Good luck

I bought a pair of injectors (primary and secondary) $225 ($240 after tax and shipping) They do sell a highflow secondary but its not stock. Warranted for life, can't beat that. They're in Tampa FL. I'm in Central FL. so I got the m next day with regular shipping.
Hope that helps
correction: just checked the website and they list the warranty as 12 months

I love the stock injectors - had one replaced with used - still good.
How do you like these? How is the fitment with the spacers? does the stock pigtail fit?

Fitment with the spacers was fine, since these have angled connectors (that why the spacers). Everything hooked fine, Nice and tight.
The stock(?) pigtails are standard GM plugs (at least on mine) Car was falling on its face under boost (anything over 3k-3.5k unless you slowly accelerate)
After I put in the pair it's been running fine, pulls nice and boosts good. Boost buids up at about 2.5k-3k and goes up from there under load.
