Rough run on start up
 

starts ok. Sort of hick ups sometimes like bad timing in gas model. Appears to run fine after about 10-15 min warm up. Idles ok. Step on fuel it chokes & no power. Surges only a bit when idling every now & then. Has new injectors, fuel filter, radiator, trannie electrical harness new. Any ideas?

A whole lot of possibilites this question, with a 94 and single lift pump power OPS comes to mind, bad lift pump, clogged in tank fuel sock, bad glows, dirty GNDs and lastly timing you have access to a bi-directional scan tool ?

New injectors or re-mans?

Where did you get them?

Bosh or Bosh knockoffs?

Bad miss/hard start before the injector change ?
