Hi Everyone,
Im quite new here, so would like to say HELLO!Please forgive me if will make some mistakes in writing but Im not native English.
I hope you might have some suggestions regarding my problem. Alright.
I am very happy owner of lexus ls430 2001 form march 2011.In May I decided to convert Lex into lpg system due how many miles I drive per month.From March until now I have done 25000 miles.Driving lot. Few weeks after installation car started to loose power on lpg and when switched back to petrol all was working fine.
I went to guy where I did installation we checked everything and didnt find any problem, he adjusted what he could and seemed to be fine.On the way from Germany to UK suddenly check engine came on and car slowly reacted on pedal depress, accelerated from 1000-2400 then PRM increased slowly to 4000 and then 'new knock' and power back.I managed to get to UK but it was nightmare. So went straight to lpg installer we checked all and found that Magic reducer was causing problems,not enough pressure.We checked OBD codes and came with 0325 Knock sensor. The lpg installer put second reducer, we changed both knock sensors on new ones and now seems to be fine if I drive gently up to 3000RPM (driving on petrol), above 3000RPM check engine comes on with 0325 code.So we swapped knock sensors but still same code is coming out - 0325.If I drive on lpg check engine comes on straight away. I do not know what we might do else.
P0325 - knock sensor bank 1 sensor 1.
Any suggestions and help please????
Marek
