Bogging WOT??

[7mgte1988]

Ive checked codes and nothing but maybe a 52 when iam cruzing. The car just now starting doing this 2 months ago after HG fix. Has any one had this problem cuz i was thinking coilpack,fuel filter,and fuel pump.

I know thread has been posted somewhere

So you don't think the 52 is a problem?

NO cuz i had 52 way before my car started doing this

 

[jetjock]

I see. So you're saying the car was running OK with the 52?

Yea it was driving better than what it was now. i can start the car and drive normal and the when i start going into boost the light comes on

 

[jetjock]

Maybe you should fix that first.

To be honest the light started coming on the night i messed my last motor up and it never went off since. do u think thats got something to do wit it??

 

[jetjock]

Once the light comes on does it stay on until you turn the engine off or does it go off on its own?

Yea it stays on till the engine goes off

 

[jetjock]

As I suspected. You really ought to fix that...

So is it possible for the light to come on and go off when the engine running??

 

[jetjock]

Yes but in this situation it won't. Ever. That's why you need to fix it.

 

[7mgte1988]

Yes but in this situation it won't. Ever. That's why you need to fix it.

can a misfire cause a 52

 

[jdub]

No, but a code 52 can cause a misfire.

 

[Nick M]

Fascinating...

 

[7mgte1988]

like if the car warms up and i start driving it wont come on till iam getting ready to go in boost. i hate to start guessing but can a defected coilpack cause this code 52?? its been 2 1/2 years since i changed it.

 

[Nick M]

Have you looked up what 52 is yet?

52 is the knock sensor right. can a misfire make the engine shake as well? or preignition?

I got a similar problem, As far as I could figure out, its not boost dependant, nor RPM dependant, but whenever I would go WOT or even just put the engine on heavy load, the AFR would go RICH and the engine would bog down. Does that sound kinda like what you got? BTW, My check engine light is not on.

Sounds kinda like what got but mostly under a heavy load. the car is pretty quick up intill 80mph then it starts to spurter and it will ride good over 100. and i dont have wideband so i dont know AFR
