Idling Rough - Help!

[1970KE10ROLLA]

FIRSTLY DISREGARD THE CAPS MY LAPTOP IS KINDA BROKEN

 

SO ANYWAY I GOT MY CAR UP TO DARWIN ABOUT A WEEK OR SO AGO AND HAVE BEEN DOING SOME PREVENTATIVE MAINTENANCE ON IT.

 

THE PROBLEMS STARTED TO HAPPEN WHEN I DID THE PLUGS...

 

IVE GOT A 3K ENGINE IN MY KE11 AND I PUT NGK 5ES PLUGS IN WHEN REPLACING THEM.

 

I DIDNT REALISE AT THE TIME THAT IT ACTUALLY NEEDED TO BE THE NGK 5EY BECAUSE THEY HAVE THE RESISTOR IN THEM.

 

SO ANYWAY WAS DRIVING ALRIGHT FOR ABOUT A WEEK AND THEN IT STARTED TO REALLY IDLE ROUGH AND NOW ITS PRETTY BAD.

 

I HAVE CLEANED ALL THE POINTS ON THE DISTRIBUTOR CAP AND ROTOR, REPLACED THE LEADS BUT ITS STILL DOING IT.

 

HAVE I WRECKED THE DIZZY OR THE IGNITION COIL BY PUTTING SPARK PLUGS WITHOUT THE RESISTOR IN FOR A WHILE?

 

PLEASE HELP

 

 

THANKS

Hey man, I don't think it'd do any damage, if you go to the NKG website you'll find this under FAQ :

 

"Q: When should I use a resistor spark plug?

A: NGK "R" or resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking.

NGK strongly recommends using resistor spark plugs in any vehicle that uses on-board computer systems to monitor or control engine performance. This is because resistor spark plugs reduce electromagnetic interference with on-board electronics.

They are also recommended on any vehicle that has other on-board electronic systems such as engine-management computers, two-way radios, GPS systems, depth finders or whenever recommended by the manufacturer.

In fact, using a non-resistor plug in certain applications can actually cause the engine to suffer undesirable side effects such as an erratic idle, high-rpm misfire, engine run-on, power drop off at certain rpm levels and abnormal combustion."

 

So I think if you just switch to normal plugs you should be fine.

 

good luck

bump up the idle speed and don't worry:)
