look at my plug wires

So I just did a plug change and noticed something that was not to appealing. Check out my plugs, then look at the condition of my plug wires.














And now the plug wires. Both had a small abrasion. I tend to think this is actually from the age of the wires.

time for some new plug wires

Yeah, plugs looked decent though.

yeah

How many miles are on those,are they stock plugs

35k on the wires. The plugs are not stock, but they got replaced anyhow.

I think you found your 4k RPM miss ...

I hope so. We will see this morning.

plugs look a lil lean

if that's white, it's lean as crazy. if it's chocolate, light brown color with a line just above the curve on the wire, then it's good. Timing line should be right above the curve on the wire.

They're copper plugs.

look on the bottom to see the number. if it's BPR7ES, it's stock temp, if it's BPR8ES, it's one step colder.

That and you need to measure the gap. You'll want to be .032 if you're stock mods, .024 ~ .027 if you're modded.

Yeah, I was running BR7ES, which are 1/2 step colder. Gap is fine for my mods.

Nope. It's still there.

4k rpm 5th gear misfire? that's 03 ecu being too sensitive. you need mitsu flash, then flash again with aftermarket. that fixed my problem with misfire.

Misfire was in 3rd and 4th from what I remember.

Mostly 3rd and 4th, and occasionally in 5th.

mine was always in 4th and 5th, mostly on 5th while cruising.

I have read that the 03 ECU is a bit sensitive, but this just started happening.
