Small miss or stutter at wot

**99GT2dr** · 02-24-2015

Really? Damn, going 3.5 to 3.2 my belt is nowhere near tight enough, and that's less of a change than stock to 3.4. 3.2 belt won't even fit over the 3.5.

**Scottydoggs** · 02-24-2015

the stock belts not as tight as when the stock pulley was on, but it holds fine.

**99GT2dr** · 02-24-2015

Then I stand corrected. It's probably my Uber horsepowerz that was causing my slip, the stickers man. My GTP had comp cams, sparkplugs.com, AND K&N stickers on it. All installed under the hood for even more gains, that was probably my problem.

**Scottydoggs** · 02-24-2015

stickers will do that all the time lol

your belt maybe old and worn out, that will let it slip.

**ItHurtz** · 02-24-2015

My sticker added so much horsepower my belt kept breaking so I dont run one no more

To the op, 103's are way to cold for a 3.4. 104's or bust

^^^^^^^^^^ love it!!!!!!!

I bet you have a faulty coil. Try putting some dielectric grease between your coils and icm. If you can scan for misfires it would lead you to the bad coil. If your wires are old change them to. Al104s but tighten up the gap to around 45.

**99GT2dr** · 02-25-2015

Duuuuuude, I saw that turbo sticker, but I was like naaaaaaaw I need this trans to hold up a while, lol. Need to save up for a TEP sticker first.

103's way too cold for your setup, do 104's and run the widest gap the car will let you.

seems like you were getting a little blow out. Glad to hear you got it fixed

**xxburkettxx07** · 03-01-2015

Ok I still have a lil stuttering going on at wot not all the time just sometimes lol.., what is this blow out you speak of??

**Scottydoggs** · 03-01-2015

spark plug spark being blown out pretty much.

try opening the gap to .50 .... 45 is kinda small.

**xxburkettxx07** · 03-01-2015

Can the gap being to small cause my problem ? It'll be a few days till I get a chance to re gap the plugs. Dang this sucks

**Scottydoggs** · 03-01-2015

you dont want to hear this, but its best to play with the gaps and see what feels best. i went through two set of different heat range plugs, gaped em both sets at 60,55 53 and 50 seeing what felt best. 104's won at 0.50.

so i had the plugs in and out a lot over a few days time. with headers and all the pull brackets removed i dont even rock the engine to get the rear plugs out no more. can swap em in like 10 to 15 minutes.

and you really need a down pipe and plog or a set of headers for that 3.4. that could be the whole issue still.

get the t app yet? i bet its slammed with KR.

**xxburkettxx07** · 03-01-2015

I've never rocked the motor to take out the plugs lol I have hollowed out cat n u bend right now I've got 3"off-road down pipe new resonator n borola mufflers just waiting to get it put on, I got the torque app the bluetooth obd2 will be here by Tuesday

**Scottydoggs** · 03-01-2015

the dp will help some. try to find a plog if you can.

id keep out of boost till you can scan it. lots of KR = chipped pistons.

im on a 3.4 and 1.95 rockers and headers and had a hard time getting rid of the kr. had 4.8* on the stock tune. zzp tunes are not the best out there either. most learn to hate it.

**gtpguy98** · 03-02-2015

Last time i was having a misfire at wot it was my icm. Thats why i was saying if you can scan for misfires and their all over the place a wot its probably your icm. If its one or two cylinders all the time it might be those cylinders coil.then again ive had misfires at wot because my plugs had to many miles on them. Spark blow out happens at the higher rpms like 5k and above. If it is bad enough you can feel but most of the time you wont notice it. I didnt till I got mine on the dyno and saw it on the graph. Just for reference im running a 3.0 pulley getting around 11.5 psi and im running Al103s at 35 and i change my plugs every 6000 miles.

**xxburkettxx07** · 03-03-2015

Ok it misses quite often not at just wot in overdrive going up hills on hwy it will cut out sometimes plugs are new gapped 50 new wires checked all the coil packs replaced icm just to see no difference I just put on supercharger gasket a garrlock one and throttle body gasket I have no check engine light I either.... cam sensor, crank sensor, fuel pump??
