damn that would make sense even if im not getting a code it could be that...i had an isue once on my buddys evo and it was that but his was acting different than mine so i mean it is posible....Thanks man I allready called them and told them to check it...Your the first person to give me some advice that i havent gone through in my head or thought of or checked man...thanks alot bro

 

Log the RPMs while the car is doing that. I had the same thing happen to my Talon, but it ended up being ignition related. I logged the RPMs and they would spike to 10000 when the car was bucking. Replaced the coil pack and all was right with the world. A cam sensor going faulty should LOSE the RPM signal though, so it should spike to 0. I never got a code either. Something to consider!

 

i changed the coil packs first because i thought the same thing and i did have a misfire code but that was due to a broken o2 sensor wire and posibly the coil packs

 

man i cant wait to post in here what was wrong and how my cars driving awsome!!!! Im cold as hell and having to drive my gsxr 600 cause all my other rides are in Texas ahhhhhhhhh lol

 

1) over boost protection. is the car tuned? how much boost are you running? whats the boost limit set to?

2) spark plug misfiring, whats your plug gap at, what plugs?

3) boost leak causing it to run very rich at WOT. are all your pipes connected and tight? no vacuum lines popped off anywhere?

 

not over boosting!!!! i have it buschur tuned my plugs and coil packs and not pipes or anything like that...its a drive train problem or my cam position sensor or my car just doesnt want to leave ohio lol

 

rule out the drive train then. get the car warm which is when you say it does it. then get the car rolling forward, make it buck which is the problem you are describing. then get the car rolling again and try the same thing with the car in neutral. does it buck? does it make a popping noise if you turn the steering wheel hard left or right and roll forward?

and for the first 10-20 minutes when the car is cold, you can floor it and it runs perfectly fine?

 

yeah bro it still bucks even in neutral after it starts happening...it will start and i can shift into neutral and it still does it...so strange i know...it doesnt pop or anything when i turn the wheel just bucks the same...Yes it drives great cold i can floor it and it runs perfect cold....It mostly starts bucking on deceleration but it also does it giving it gas to...this is so crazy lol....i need some tom cruise voodoo magic or something

 

Paranormal Activity!

 

well if it does it even in neutral it rules out diffs and axles. take your intake off and feel the turbo compressor wheel.

does pressing the clutch in have any effect on it?

 

trunk monkey. Feed him.

 

the dealer said the turbo is fine...its the damndest thing and i just cant figure it out...im hoping its the cam position sensor

 

Sorry to hear Rob. Check out this, as it is cam sensor related

Perhaps youve pumped some $hitty gas in your car?

 

thanks paul...im pretty sure it is the cam sensor

 

stupid question....is there any after market cam sensors???if so who makes them
