I think I have an oil sensor problem. For starters, every time I start my car it says I have no oil (even though I do) but this is not my main problem. After about a minute or so of driving (usually when I accelerate to make it up a hill) the car makes a huge jolt or jump if you like as the sport and snow lights flash away in unison while beeping 3 times to indicate an issue. After this jolt, the revs run slightly higher then normal but wont go over 2000rpms. This is very frustrating in traffic because my car will now take AGES to pick up speed. The strange thing is that this will only happen when my car is cooled. As soon as my temperature reader/indicator shows my my car has been warmed up, I stop and restart the car and then I have no issues. But if I try restart BEFORE the car has warmed up, it will do the same thing again.
I have done a little bit of google-ing on this and it does appear to be a common issue. I've seen it referred to 'limp home mode' but no one seems to offer a solution. I've read about plenty of people spending hundreds or more trying to solve the issue but failing. I don't want to be one of these people.
I've taken it to get a diag and the guy said there were 13 faults which he apparently fixed but I have seen no improvement. He said he also 'reset' my car computer. My mechanic told me he wants to clean out the oil filter and sensor first and if that doesn't help then replace it.
Ive has this issue ever since I bought the car second hand about a year ago so it's probably had this issue for a lot longer than that.
To date, I have spent about $700AU trying to fix this. I would rather not spend any more if there is no solution. I had the fuel pump replaced, the diag/repair and a general service / look over.

Please help me!

Thanks, Taylor

13 faults. Do you recall what they were? And what did this guy actually fix? Need a bit more history of repairs. Do you currently have any lights on in the dash? I would get this thing scanned for any fault codes. By any, I mean your car has numerious systems. If you go to a parts store for a free scan, they can usually only get engine/pcm codes, airbag, and abs. If you have any bodycontrol codes (however irrellevant it maybe) transmission codes, etc. A trip to an honest garage for a quick code scan shouldnt be much. Some guys do it for free. We need to know what exactly your computer is triggering.

Thanks for the quick reply!

I had a friend take my car in for me that day as I was unable to. Rookie mistake I know, because she couldn't tell me many details that afternoon. She told me that he said they were 'glitches' which he spent 2 or so hours cleaning / working on and he told her it had fixed the problem. All I know is that it cost me $500 and it didn't fix a thing!
There are no lights like 'check engine' warning or anything like that. Only the flashing 'sport' and 'snow' indicators that go out when I restart the car.
My car manual says that when this happens its and operating fault but doesn't go into further detail.
I did a bit more googling and have found many people suggesting a gearbox problem (I pray its not)
I spoke to another mechanic today who thinks its the oil sensor but I have arranged to have another diag on it next week (Only $100 this time)

Thanks, Taylor.

What did the work on/clean? I absolutely hate it when a dealership, or a garage cant figure something out, and they still charge! You had 13 fault codes originally. They should have checked your vehicles data. It will store info when it sets a fault. (Freeze frame data) from here, they should have noted every code, and cleared them. Then driven the vehicle. Once you reset the vehicles memory, any hard faults usually return right away. You fix these first. Most of the time, these will keep the other codes from comming back. I dont want to see you waste your money. Disconnect your battery, and touch both the battery cables together. This will reset your system, and the Keep Alive Memory. From here, drive it until your Check Engine light, or any other light come on. Go to a parts store for a free scan. Let me know the codes
