Were the GP platinums too hot of plug? That can cause the pinging you were describing in the last thread.

Just goes to show you, stock can be hard to beat. Turns out the Toyota engineers weren't so stupid after all!

shafner30

does anyone know if those ngk gp platinum spark plugs have a hotter heat range?

shafner30

then the stock bpr5ey ngk

yayfortrees

They probably do, do you know the number of the plugs that were installed?

shafner30

it was ngk bpr5egp spark plugs

yayfortrees

Well, that's not it then. I thought maybe a parts guy had grabbed the wrong ones by chance. Out of curiosity, do you know what your compression is?

shafner30

no i dont knowwhat the compression is

PismoJoe

I'd guess its ok since you said its running well now with the correct plugs

yayfortrees

I was just curious if he maybe had slightly higher than normal compression. I would like to know why the different plugs would cause pinging, even though they were the right heat. Were they causing pre-ignition, or just what? Anyway, it doesn't really matter since the problem is fixed.

I run Bosch Platinum II's with no problems at all.
Just saying.

were they gapped properly?

problem that i've seen with any pre obd2 motors and platinum plugs is that they foul easy and make a hotter spark even though the heat range is the same. stick with what the motor calls for.

Absolutely right. Your plugs are not the problem. I run the NGk Platinums and could not be more happy with them. The heat is almost the same as stock specs.

You have other issues going on. I would look at your cap and rotor. For your cap and rotor I would only go with stock OEM parts.

yeah i run platinums... no problems

rotor button, distributor cap, or crossed plug wires would be my guess. i'm also running ngk platinum's with no issues.
