Put new plugs in today, (easy!!!) I have a uk my00, with full decat and panel filter, I put NGK PFR7B plugs in, and it now seems to run slightly less smooth than it did, but also seems better when on boost, and giving it a bit of stick, does this sound right?
I did disconnect a lot of stuff due to space, could something be not connected right, or would it just not run at-all if I'd forgotten something???
All thought gratefully read!!

 

Hmmm....check your idle pipes, and all the vacuum pipes that go back to the air intake.

 

still messed it up though

 

Did you check the gap before you put them in?

 

No I didn't check the gap, the guy at Power engineeriong said thye always spot on out of the box, It does seem to be a bit better today, I'll see how it goes, and maybe take them out to check them.
Cheers.

 

I've not had any NGKs set right from the box so far. Suggest gap to 0.7mm for best results.

 

I think the 'guy' at Power Engineering who told you that should take em out and re-gap em for you!!!!!!!!!!!

Looks like I might be taken them out then, seeing as 'The God' (JB) has spoken!!
Cheers.

 

I just regurgitate what Bob says

 

Fitted a set of 6B's this arvo and they needed re-gapping to 0.7mm.
I think they were probably about 0.8-0.9 straight out of the box.

 

Thanks all,
I'll defo have them out to check them when I get a spare hour or so, I was amazed at how simple ot was once you've removed a few bits, strikes me that everyone who thinks iits difficult has not worked on a lot of cars, I have!!

 

So, should I gap them to 0.7 then, will do it when I get an answer!

 

I've never gapped spark plugs before. How do one go about doing that? What is the best way?

 

You tap'em on a hard surface! Then put a feeler guage in to measure it.

Or for posh people you'll have a gapping tool to do it.

I on the other hand, pay someone to do it for me 'cause I'm filthy rich

As long as they do the job correctly Floyd!
