Hello Everyone ! After more research Im still at a loss And could use some help. First off I have no Codes, Setup is cai, new plugs, wire's, disty,(also tried old one), fuel pump, both new fuel filters, timing is at 13 degrees using 93 octane , new pcv, ground kit, header, new o2 sensor (Tested at 0.93 V) and full exhaust. also just tested tps.
: Problem is before engine is warm both under Full throttle and partial throttle the engine will lose power like the fuel is being cut off but does this randomly at no specific rpm or throttle posistion but seems to fade off over 5k rpm. This problem dose still persist when engine is warm but is less noticable. I have ran stp, and lucas fuel injectors through last 2 tanks, fuel economy has been down around 26 Mpg which is low considering i always shift under 3.5k usally under 2.8k rpms dont ride the clutch and drive gently, Most of the time

. I have swapped out plugs wires and disty and still have had the same problem. One thing i should note is i did have the fuel injector wires cut at one point for old fuel injectors, Is it possible to hook them up backwards and still run ? also engine idles smooth could this possibly be fuel pressure regulator. Really need some idea to fix this problem im sure when i fix the fuel issue mpg will go up. Thanks in advanced !
