So as of yesterday my engine light came on, I was driving to Toronto and back. On the way back I tried to accelerate on the highway and I heard a grinding noise. I backed off and pulled over and my car died when I stopped it. Hunted for an idle first. It started back up a little rough and then I tried to drive it again and anytime my foot compressed the pedal past a certain point (at least that's what it felt like, didn't FEEL RPM related but I could be wrong and pushing the pedal down does cause the rpms to go up but when I engine braked in 2nd the rpms went up and there was no hesitating) there was a bad grinding noise (fast and changed in pitch depending on the gear I was in) and the engine light would flash (yet surprisingly not stay on afterwards). Today I went and filled up on fuel and it seems to have improved it a bit, as well I went through a heavy duty car wash to try and clean any crap that may have gotten underneath the car.
So! In short.
SYMPTOMS
1. Flashing Cel
2. Grinding Noise
3. Dies at Idle
4. Hunts for Idle
POSSIBILITIES?
1. Fuel pump/pressure?!
2. ESS needs a clean bad and is causing the ECU to think my car is misfiring..
3. Something causing back pressure in the exhaust system (cat?)
4. A problem in the ignition (Harness, Plugs, Coils (BHR), Wires (BHR))
5. ????????
As a side note my engine has less than 50000 miles but it is an engine I bought so it's not covered by warranty and I can't take it to Mazda. The engine itself IS under warranty though so if it turns out to be a problem with that it's not the end of the world.
Transmission has been revamped recently with new clutch and flywheel.
Relatively new coils, plugs, wires.
**Coolant has been overflowing and spilling everywhere to the point where it damaged my power steering (getting a new harness because cleaning didn't work)
Please help :):crying:
EDIT : The weather has been super awful (40-50 cms of snow recently and driving has been bad, I've tried to minimize but I had to drive a fair amount on the day it happened and it was a struggle to say the least)
So! In short.
