What up guys? i did a long search and did shoebox and brents website but not sure still. i have a 93 z with 113,000 miles, all i have done is put an LPE intake and throttle body b/p. my car has seem to have lost some power on the low speeds but picks up later. also i have seen that my fuel milage has gone down, i got 145 miles on an extra full tank last time with just regular use on to work and back. i just bought the car and the guy didnt seem like the modding type so im assuming its all stock. dont know when the last tune up was either. im ready to change the plugs and wires this weekend though. but the weirdest thing is that i poped the hood the other day and noticed a loud ticking sound coming from the injectors. after a search i learned that the injectors do tick but mine can be heard over the engines regular noise, is that normal? also i could feel them tick pretty good if i put my fingers on them or on the fuel lines or rail, more on the front four than the back four. could they be dirty? need help before i do something drastic!!! some guy told me to also check to see if im not leaking fuel and to check my EVAP system.
