Hi guys I could do with some help I have had my Holden Jackaroo 2001 Monerey 4JXI for about 2 years now. In the last 6 month I have had the head crack on me with cost me $6000 to fix the first time and the other 2 times was covered under warranty. After they had fixed it for a 3ed time they gave it back to me and only 10 mins later the car stopped on me all of a sudden. The engine just cut out and the power steering locked up and the brakes were hard to push. The mechanic told me it was the Oil rail pressure sensor. Witch Holden had only replaced 18 mouths ago. The mechanic replaced the ORPS with a brand new one. Straight after replacing it the car sounded like ###### and there was no throttle response. you had to keep your foot on the accelerator to keep the engine going if you took your foot off in would die. the car would not move and sometimes you could not get it to even turn over. the mechanic put the old ORPS back in and now it will only run for about 10 mins max. the car runs fine and sounds good. the mechanic told me that they had hooked up my car to there computer and that it had said the ORPS needed replacing. But bear in mind that after I took my car there I have not heard a good thing about them and how dodgy they are.
My question is dose anyone know why there is no throttle response after replacing the ORPS.
