4AGZE spark plugs Mis fire issue

[D1]

hey guys i am just replacing my spark plugs due to misfire issues. I am finding difficulty finding upgraded plugs ie twin spark iridium or platinum. 4AGZE (4AGTE) was not in the dudes manual so i gave him the part number i was using NGK BCP7E S wondering if you guys know of any? part numbers would be helpful? Also whats the difference between resistor types and non resistor? WHat do they resist?

answer my own question

hey dudes just another spark plug question (that ill probably answer my self)

I ended up buying NGK BCPR6EIX-11

Iam still getting misfire i was told this is due to the gap. But on my plugs it says to not adjust the gap? does anyone know what the gap should be?

[mc68]

well if the gap refers to the 11, then 1.1 is a tad too big...try 0.7-0.8

and if your careful then gaping the plugs shouldnt damage anything.

u running coil packs ?

[D1]

yeah sure am man.

[D1]

changed the gap to 0.711 still getting misfire though i did chip a bit of one of the plugs. Ill be getting one new plug to replace it gap it then see how it goes. Never new this was such a hassle. If i still get misfire would it be the coil packs?

Coil packs getting hot and playing up ?

[D1]

hmm un sure man trying to figure it out.

if its still missing even with fresh plugs then your problem isnt plug related. Wether they are gapped at 1.1 or 0.7

Auto electrcian tiem for you.

Coil and/or ignitor, its a frequent thing finding misfires, especially in ignition system, there always easy to fix, but finding theproblem and fixing the right part is the trouble.

If closing the cap helps with misfire(after fresh plugs installed) then your trouble is coil/s, ignitor or to much resistance thru bung lead/s.

a weak spark is probably occuring.
