Thought I'd get started with a quick question. I have an 04 with the 5VZFE V6.
Bought it used, had it checked over thoroughly with a trusted mechanic. Replaced coils (those are rediculously expensive) wires, fuel filter, plugs.
First problem, it started missing, found that the electrode in the plug had been eaten away to a point. Was told to buy double platinum plugs, but it didn't explain why it was happening. This was after about a years worth of driving.
Yesterday, it started missing, so we pulled all plugs and they looked fine, replaced the#5 from what the computer said was bad, and it seemed to fix the problem, but it started running rough again today.
I'm thinking now, mybe bad wire/coil, (hope not), or maybe a bad plug, but NGK has a fantasitic record.
Any suggestions, comments would be greatly appreciated.
