Hey guys I need help!! I have a 1990 convert 6 spd 87000 miles on it usually runs great about a week ago it started acting up.when engine is fully warmed up it has a low rpm flutter (misfire) so far I have changed the plugs wires dist cap and rotor,fuel filter and the knock sensor and though the plugs and wires made a noticeable improvement overall the problem is still here.when the car is fully warmed up and it is doing the missing if i shut her down and imediatley try a restart it sometimes wont start or it is reluctant to start.wait a couple of moments and it starts right up??/any ideas?? ps no lights are coming on either.I havent hooked it up to a diag machine yet.:confused

Bad injector(s) maybe ?

I agree with JimBob C4 could be injectors, could also be the fuel pressure regulator.
Pull the vacuum line off the regulator and check for fuel in the line. If so your diaphragm is bad.
