Well yet another update in my problems.
Got the car back after he did the radiator, the transmission appears fine now.
Last night once i got back from work, did some paperwork and then went to go back out shopping, the car wouldn't start.
When placing the keys in the ignition and turning it, it would not even attempt to turn over, it just comes up on the dash, Fuel Guage Error - Contact Dealer, then Very Low Fuel warning then Service Vehicle Soon.
After trying over and over to get it started, i ended up pulling the battery terminals off and back on and then the car would start.
The first time it started after doing this, the engine started normal, then reved down heaps as if it was going to stall, then it went normal, but the dash instantly give a Check Powertrain warning, no more Fuel Guage Error or Service Vehicle Soon message.
I decided to turn it off and try again, this time it started all fine but the Check Powertrain warning still came up.
Took it for a little drive after this to see if it was going ok, all appeared ok (from what i can tell).
Drove the car back home and this morning the Check Powertrain doesn't come up anymore.
...This car is getting weirder as it goes.
I've gone to another mechanics who has a computer to run diagnostics on it, but they are booked out till Next Week.
The original mechanic is coming over to check the car after 2PM today.
Could this at all be related to the O2 Sensors or?
After forking out a loan to get my car fixed, i don't want to wasting money where it shouldn't be getting wasted.
I NEED this car for my 2nd job, and so far its been 2 months without it and is starting to really P*** me off.
