Plug and cap compatibility, well I never
Just checked, plug is a br10eix (irridium), but have also tried many others.
Cap has TD T-150 stamped on it. Not sure if it has been replaced in the past.
How do I check cap Ohm rating?
This doesn't cross refernce with any NGK cap number. Sure it's not TB --EM/A
?
Need to have a 'R' in the plug number or a 5K Ohm cap one or the other but not both or niether.
Lozza,
I'm running a non resistor cap AND non resistor plug, wasn't aware that this was a bad thing. Why?
From NGK website
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.
