92 chvy pick up surges poor idle
1 have a 92 chevy k1500 5.7 eng,200100. Miles on it, the fuel pump went out , changed it. When I start to go from a stop it feels like trans is slipping,rpms fluxuate in park. Changed trans fluid, it looked and smelled clean, still same. At idle it surges. Don't remember having this problem before the fuel pump left me sitting. Did complete tune up , cleaned fuel injectors with inj. Cleaner.could I have a bad fuel pump or do I have a problem with the tbi unit? Any ideas?
Checked for vac leaks all good no codes
