can any garage read the ECU codes? or do i need to visit a mazda specialist?
exhaust does seem to be blowing a little from towards the front of the car, but how much effect can this have?
ive just used the £40 i put in last week and got about 70miles which equates to 10mpg, and only maybe 3 time did i drive it hard, but only for about 1/2 a mile each time, i cant afford to run it at those costs!
Id fix this first mate,if it has a blow it will cause real flooding/fuelling issues as the ecu reads more o2 it throws more fuel into the engine thin king its running lean causing the symptoms youve experienced.
and it can lead you down the path replacing sensors/switches etc.
one of my own cars has a leaking second turbo and its horrifically rich to a point it it doesnt want to start on stock ecu
