Cory....bro... so what you're saying is you do need to modify the "stock" set gap distance on the tC's....IF you're running a FI setup then? Good to know...I'm on a N/A setup so I wasn't aware of that need with FI.

 

yes you need to gap down i run a little over 30/1000 i have never had a misfire code the only code i get is the ocassinall 0172 bank one rich

 

did you gap them down and is it running better now

 

Always check your plugs first.

If you've just installed new plugs, they could still be fairly clean - as Paul mentioned, it depends on how hard you drive.

Always make sure your gap is between 28-32 (it's what I use.. others may offer different numbers). Right now my plugs are at 30 and everything is great.. I run 1 step cooler NGK Iridiums.

 

heck yes to 30

 

28-30 thousandths

 

so i checked them and they're at about .028 already should i gap them lower?

 

No keep them there... that should be fine.

Now that the plugs are out, how do they look? Want to post some pics?

 

lol i just put em back in they looked good just a little soot around the top of the treads and the tip had some whiteish greyish deposits

 

pics coming

 

 

As far as I can tell the plugs look fine.

Does your F/IC have the resistor mods?

 

yup

 

You can do the following.. get a multi-meter and check

1.) Cam position sensor - s/b 835-1400 ohm cold or 1060-1645 hot.

2.) Crank position sensor - s/b 985-1600 ohm cold or 1265-1890 hot.

3.) With ignition on, check with meter between pins 1 & 4 of the coil pack for correct voltage.. s/b 9 - 14 V.

 

i was thinking maybe coil pack told him to switch out the bad one to another place see if it throws code in that cyl

 

are the cylinders numbered from right to left 1234

 

yes just switch the outer 2

 

so i havent had the misfire code since i messed with the plugs the other day but now im getting the cel p0138 wtf
