So i bought a set of NGK plugs and wires
BUR9EQ
BUR7EQ
NGK 8156 Tailored Magnetic Core Ignition Wire Set

I cant seem to figure out where each set of plugs goes and which wire is which

I really don't want to cause any issues doing a tune up

 

put the bur7eq's in the bottom plug holes and the Bur9eq's in the top holes.
The plug wires: the Lower spark plugs hooked to the coil near the Headlight.(although you should put them as Front lower plug to L1 marked on coil and Rear lower to L2 on coil,they CAN be mixed up,as they fire at the SAME time)

The Upper spark plugs: the upper plug at the FRONT of the engine goes to the coil wire that protrudes Closest to the Front of the car.(marked T1 on the coil)..the other wire is a NO brainer!
NOTE: you have to make sure that the plug wires are EXACT for the UPPER plugs.They cannot be switched.If they are the car will Run like **** and you can damage it.( I am not responsible!)

 

Change them one at a time. Including the wires. Use a little anti-seize on the plug threads being careful to avoid the electrodes. A little di-electric grease in the boots of the plugs. Simple.
If it helps...Leading = L= Lower plugs on the housing. Trailing = T= Top plugs on the housing.

In the future it helps to post what year/model RX7 you're dealing with.

 

oh sorry thought i did post
its a S4 1987 na rx7

I am sadly still waiting for one set of plugs (i hate ups)

 

I changed the plugs and wires yesterday
the car is running a little better
still there is an occasional misfire?
it sounds like the engine just flumps over every soe many revolutions
and it has a hard time holding idle at 700~ rpms
