Suddenly getting 10 degrees of KR

[Tuner-Extraordinaire]

yeah thats a bit low for 3.6 pulley on a genv.

 

[Tuner-Extraordinaire]

Should be more like 18 for IPW

misfire detection yet?

Has it done it with a full tank of gas?

 

[buickman104]

Yup with the full tank.

Look at O2's not IPW's. You can't tell dick from IPW's except that you are running out of injector/fuel pump issue. Which happens around 20-22 IPW. His mounts are nearly brand new. You'd hear/feel a mount letting engine vibration get into the body.

 

[buickman104]

Mounts are new. No mount clunking or excessive movement.

LCA's good ? No worn out bushings ? Cradle bolts tight ?

 

[buickman104]

control arms are both new one with about 5,000 miles the other with about 600 miles. Cradle bolts tight and new bushings all around.

 

[BillBoost37]

My 600ft lb 1/2" gun says his cradle bolts are good'n'tight.

 

[oldsman105]

Dumb thought, how much timing is being commanded at WOT? he loaded the 04 GTP tables recently ? maybe its too much?

 

[BillBoost37]

E...it might be. However it might be the weather we are having. I'm seeing some odd stuff. Haven't had a chance to grab the pc and tune it yet.

every resolve this problem? having similiar symptoms

 

[buickman104]

Once the weather warmed up my KR went to the normal levels of KR i see with about 14 degrees of timing at WOT. Noticed my KR gets high only when it's around or below 30 degrees.

Did ya ever figure out what the problem was?

Sounds like you need a bigger pulley -- And an all weather tune.
