sounds like the timing is off.. btw this is the wrong section r-tard

no CEL? the plugs should tell you what's going on

Re: missfire issue tuning shit box build dirty d fluxcore t25
 

Whats the gaps on the plugs and the engine mangament?

He said they're gapped at .025"

Iridium plugs were a big waste of money

You answered your own question. If pulling the gap down on the plugs helped, then you have excessive air-gap in the cap/rotor. Change those. Also, only use OEM plug wires or NGK (same as oem).

try using zex nitro/turbo plugs only $25

Re: missfire issue tuning shit box build dirty d fluxcore t25
 

or try using ngk like previously stated and not waste 25 dollars.
