keep in mind manuals run a little higher idle RPM than automatic trans. also 4.3 injectors are different than 5.7. I learned this after chasing an idle,. surging, lean problem for a long time,. bought truck as basket case, had blown head gasket, some parts were in the bed, some in the cab. short block was in the engine bay. I just assumed the intake and throttle body belonged to that truck. I TRIED EVERYTHING, from fuel pump, to 02 sensor, distributor, and on and on and on. I got the numbers of the injectors looked them up and they were for a 4.3.. went to salvage yard, got a set out of a 5.7, verified part numbers, and the truck ran great.!!! be very careful swapping parts around,, ALSO there were ALOT of changes in the 4.3 parts over the years.
DO NOT RUN 4.3 INJECTORS IN A 5.7 !!!
