Hey all,
Now i know there are a few of these posts going around but mine is a different topic from what I'm reading.
I have a 4k-c KE55 that is misfiring. Two weeks ago i replaced a broken ballast resistor(voltage limiter beside coil) and was sweet after that. Now is becoming a little more reluctant to start. It once started perfectly everytime but now need to hold the ignition on and plant the accelerator to start it and even then conks out randomly. But once started is when the real issues occur. When driving off and revving up a little to engage the engine to release the clutch, it pitter patters like a misfire and darker smoke comes out of the exhaust when this occurs. So higher revving and slowly taking off gets me going but low revs in 1st and 2nd while driving it misses terribly and is getting worse. Under power over 400rpms it is fine and quite punchey but lower revs it is a total mess.
I doubt that the ballast resistor could cause any issues here as everywhere i called said they only carried the same one(listing) for every typre of car that needs one. But then again i don't know much to do with electrics on cars so i could most likely be wrong.
I have instaled a new alternator in the last 3 months which is fine and battery is completely charged. In the fuel i use Valve Saver Fluid and standard Unleaded.
Any help would be greatly appreciated.
