Hello everyone.

I have very delicate issue with my lexus is220d 2008. Car starts and drives, but some time loose power, starts to rattle( its gives same effect as MAF sensor issue)

I brought it to garage and diagnostics guy says "fuel pressure dropping rapidly"

Please help as this machine trying to win over human being, I figured this is insult to all of us...)

 

Actually the mechanic may have a valid point. You buy an OBD adapter, load up the Fusion OBD app with the Toyota Lexus PID pack and potentially verify this yourself. Of course you also need to know what normal is so logging data when running well and compare data to running poorly and maybe it points you to the problem.

Its that, pay another mechanic, or go on a goose chase cleaning the tanks pick up strainer and/or replacing in tank pump or HP pump.....

Basically you need a lot more info that we don't have.

Well...
I have changed fuel pump from fuel tank
Changed maf sensor, fuel rail with both sensors, sensor from hight pressure pump, cleaned dpf, cleaned egr valve. Went to 4 different guys for diagnostics.
Last night have tried disconnecting battery and connecting it back to reset ECU.
I feel like I'm doing everything in reverse in terms of finding the problem.
Today car feels good, will give it few days.

 

Any recommendations on which OBD adapter to buy?
