Cheers guys and thank you for your responds. Yes, car runs lean on both LPG and gasoline which makes me think it's not the injectors. Both arms on the intake manifold seem to be working fine, I opened it two months to take a look at the 4 little bolts that unwind in time and I cleaned and lubricated it as well as I took a look at the flaps - were looking goof. I don't have back lambda sensors, they were deleted from the ECU but are still there. I'm going to measure the vacuum in the intake manifold on Sunday and I will definitely get new vacuum lines everywhere just in case. Something very interesting - today I went for a 700 kms trip and deleted/reset the trims on departure. After half an hour of driving with average 90 miles per hour long term fuel trim adaptation was 3,4% and then suddenly without me doing nothing it started raisin reaching 13%? Makes no sense to me!? Another idea is the fuel pressure under load- some guys say both fuel pump work simultaneously whose ssp says there is a "main" one - the one on the right that runs all the time and the one on the left runs at cold start and at high engine load. Any ideas?
