my harmonic balencer has a wobble could this be making my crank position sensor not work correctly?
thats the code its saying its cutting out and dying and then blowin black cloud when restarting it did not do this before i got my transmission rebuilt by a dumbass mechanic i really need help here guys this is my DD
code numbers: p1750,p0335,c0898,c0240,c0244.
its also not wanting to start either without cranking on it awhile.
will a harmonic balencer off of a truck work for my car?

i'd be safe and just get an ls4 balancer.

blkchevyz

looks like rockauto has one for 150 or so.

Year of car, mileage and whatever other info(CAI,tune,exhaust, type of plugs and age/mileage)
Can you read live data
What wobble is it a little or a lot
Have you checked the balancer bolt to see if it is loose, torque is like 240 lb ft so real blue face tight
AS for the codes I will respond when I can get to a good internet connection... meantime check and respond with some info

SleeperGXP

06 165,000 bought it used and its bone stock all it has is muffler delete
whats live data lol dont know much
i think its quite abit and it makes a weird noise to. no i will check it hopefully its just that i went to a shitty mechanic and they replaced my power steering pump so maybe they loosened it?

SleeperGXP

bump so everyone is sure i cant use truck harmonic balencer

Absolutely not.

^^^^^ what Brian states, no aftermarkets either go with OEM and a new bolt if you are determined that is what is wrong.(be sure to follow the proper installion technique and torque) Even ATI the balancer people wont make a custom for under 800 bucks for our LS4`s even as a group buy.
I think you have a wiring/transmission problem personally but I need more time as I have no internet at home to fully explain what might be your real problem. My balancer has a wobble since the first launch and 100000 miles later it still wobbles. Tomorrow I will be intown and can use their internet to post.

SleeperGXP

ok thank you guys

My internet is screwed, everything times out before I can do anything. In brief I think you have at least a ground problem and possibly a faulty 1/2 shift solenoid in your trans mission. This should be tested as the computer is not getting the proper response within the 2 second time aloted. I will keep trying to post up more info on what is happening.

P1750- 1-2 Shift Valve Performance
Go here http://www.gmls4.com/index.php?topic=1412.0 ,(You may have to copy and paste in a new window), then scroll down to the figure #8-919 check items 11,12,13 in that diagram on your car. Then figure #8-917 #`s 5 & 8. Then figure # 8-790# 12
recommend you remove, sand and apply a little die-electric grease to each and then re-secure each.
ALSO be sure the battery terminals are clean and tight.

P0335- CKP Sensor Circuit Malfunction
This is most likely due to the P1750 trigger

C0898- Theft deterrent system
triggered by the no start/ interrupted start. Removing key from car for 20 minutes will usually clear this one

C0240- PCM Traction Control Not Allowed
again triggered most likely due the P1750

C0244- PWM Delivered Torque Malfunction
again triggered because of the P1750

Do you have access to a DVOM?

SleeperGXP

thank you very much and no what is DVOM?

Ill_Born_ss

DVOM...digital volt ohm meter

SleeperGXP

yes starts at 12.20 volts then after driving awhile sometimes goes to 15

Ill_Born_ss

no,no a digital volt/ohm test meter for testing electrical circuits, sorry should of been more specific.
