sometime it feels that turbo has shaft play

Take a can of CARB cleaner and while your cars idling spray it around your throttle body, injector seals, intake manifold, brake booster, and bov flange. If you have a leak the CARB cleaner will cause your engine to rev higher up.

will do

can i use brake cleaner ?

 

[gofer]

NO!

 

[dawid4444]

ok i will use the CARB cleaner

im just wondering why cant i use the brake cleaner ??

thx

 

[Achelea]

Because carb cleaner is designed to burn away if there is any left. Brake cleaner is not. It burns, but it leaves behind stuff that can foul spark plugs.

[dawid4444]

ill have a EvoScan in like a week

will the log of it when the car do this weird stuff helps ??
will it help ??

A logging device(EvoScan) will help you a lot. Probably the first upgrade you should buy for your car.

A WideBand will also help. Probably the second thing you should buy.


Most of the time bogging at WOT is caused by Knock or a Boost Leak.


So log Knock and WB AFR(If you have a WideBand)

If more then 3 Knock Counts(1 degree retard), you need to reduce timing somehow. Timing is being lowered because of knock and the lowered timing reduces power output/makes you bog.

If running rich, most likely a boost leak. Running extremely rich will make you bog.

If running lean, there is something wrong with fuel system or you need to up size it.

ok guys i found that when the engine is cold the car do this all the time and not at WOT just normal driving .

Is your knock sensor tight, it needs to be torqued to 17ft/lbs? If the knock sensor looks like its burnt or leaking goo out the back of it needs replaced. Post a log, it can tell us a lot more than you could ever describe...
