Misfire after new plugs

[99cobraUgotbit]

I had a bogging issue and change plugs. I used NGK TR6 gaped at .28
CEL came back on misfire 1 and 2 cylinder. Cleared it and again misfire 1 and 2 cleared it and got a p2195 with no misfire.

Now my car is notorious for needing new 02 sensors as it seems I need a new set every year. Is that normal?

not normal

I agree. Can anyone else chime in? Any ideas on how to fix this issue? New headers, new cool packs, new spark plugs, new 02 sensors?

I was having similar issues with 02 sensors after the header install.
Switched to the NGK from Van and haven't had sensor issues since.

Never had misfire codes though.

Yea I got the same 02's from Van. I'm just wondering if these codes are all related.

Anyone have the engine cylinder diagram so I can move those coil packs around. Looked but can't find one.

You got PM.

Also, You might need colder plugs than the TR6, especially for the TVS and 2.4 upper. TR7ix has been very good to me gapped at .032"

I don't have a pm...... you may be right about getting a colder plug. But! I have Ben running tr6 for along time with no issues. I was over due for new plugs when this came up
