Desperate for Legacy ej206 vdc hesitation fix

[vanislebh5]

Hi everyone from Vancouver Island ,BC Canada , car is a 1997 Legacy GT EJ206 , only 90k Km ,

I have this data from JDM app on my Android radio ,

I have been searching for the culprit of hesitation while accelerating mostly going up hill is worst...

I have a boost gage , boost is within normal limits
I have changed spark plugs
Fuel pressure regulator
Knock sensor

I have no check engine codes

[vanislebh5]

Would anyone suggest playing with the timing ?

also , does anyone see data that is off , this was at idle


My next thing is probably the MAF ....

I also cleaned all solenoids of the black box !

when was the last time you replaced the in-tank fuel filter?

How old's the fuel pump?

Can you explain a little more about what it is doing? "Hesitation" is somewhat vague.

Changed filter last year , pump is original 1997, car has only 85k km

Well it just almost cuts off , boost is normal , cleaned my maf,

Was thinking fuel pump too , but checked pressure is within specs

I am wondering if you are referring to what is known as the "Valley of Death" when the first turbo runs out of puff and the second is still spinning up. This is a well known phenomenon on the EJ206 and EJ208 with a noticeable drop in power from around 4000-5500rpm or so.

Hi , thanks RKRENICKI


It is not the VOD , I wish the car was running fine even with the VOD

It basically does this : if you are going uphill mostly (not very steep hill) and you press gently on the gas , it buckles , if you floor it , it goes full boost does not buckle but you can feel it that it not fully smooth , almost like misfiring if you had old spark plug cables and you were spraying water on them .

Thanks

If I were a betting man, I'd say coilpacks are the culprit. Sounds very similar to when mine started acting up

Thanks Durty

might be a good idea anyways since they are 26 years old
