Mk1 Mazda 3 MPS late 2009. Petrol 2.3 disi turbo
Wondering if anyone has come across this. My motor has been doing this for a while and its intermittent which makes it a joy to troubleshoot and it only happens when in boost. In the mechanics today had the diagnostics on it ..nothing no mil comes on, no codes logged and no abnormal values. He took it for a spin and typical it was on its best behaviour !
All coils and sparks have been replaced btw.
Wednesday evening was the worst its happened coming onto the motor way 5th gear and gave it a boot full 3.5k and it started to pick up then it was like hitting a brick wall felt it though the whole car. Pulled back of the throttle slight still doing it, dropped into 4th squeezed the throttle still doing it, totally let off in 4th then squeezed it on and it started to pick up again gave it a boot full and away it went.
The whole way home even in the lower gears 3rd it would do it when you asked for full throttle…it wasn’t having any off it. Thought I bust something for sure.
The only way I can describe it was like being off a cylinder…stutter…stutter..stutter like a machine gun. It can be a load of stutters till you let off or it can be like a hiccup when picking up through the rpms/ in boost.
No consistency at all but happens more often than not like today did a 4th gear pull didn’t miss a beat. Next min in 3rd stuttering again !
No smoke out the exhaust when it happens
Not sure if its got a map on it
Any help appreciated dont want to be throwing more £££ parts at just to see if it fixes it.
Anyone know a mechanic that would be handy with jap turbo car. Belfast, antrim location. Cheers
