Slight miss at idle, slightly modulating RPM and a noticeable miss under hard accel
I think I have a CPS and maybe a injector trying to die.
At idle the RPM's very +/-100 in a regular pattern, kind of a surge. Its slightly rough at idle as well and if I really put my foot in it a noticeable miss.
No odd color or smell to the exhaust or anything and its still getting 16MPG so I don't think it is a major engine problem.
It feels like someones pulled a plug wire on a gaser V8.
I am suspecting a injector not firing right for the miss and the CPS for the floating idle. Could CPS be the cause of all of it?...I guess it could be now that I think about it.
