Engine wants to die when turbo kicks in.

[spizwalt]

Hi guys,

I have had this problem for a while now and can't get my head round it.

So the engine will start and Rev freely when just parked up and not under any load. One issue I have noticed is the boost gauge invariance then normal cluster doesn't show boost, shows vacuum and increases slightly but no where near where it should sit. It has boost their as the dump valve is dumping correctly.

So basically I can drive it down the road fine, boost once, and then as soon as I try to accelerate hard again it does until I lift off of the throttle and then it picks up again...

So confused.

Any ideas would be great!!!

Cheers

Will

I f you have a cat fitted check it's not collapsed, as i had the same problem, just an idea.

Could be so many things, as John says, could be the cat.

Personally I would start with a fresh fuel filter but its also worth we had a T11 years ago that did the same and it was a faulty switch on the throttle ( engine end)

Okay will try Fresh fuel and fuel filter this weekend and get back to any other ideas would be great? Do you know the exact sensor? Tps?

I have a racing beat full system which came in the car, I believe it doesn't have a cat fitted, but will also check this on the weekend

Just checked online, my exhaust system deletes the cat so that isn't the problem, cheers for the help any other ideas would be great

It may help to know that in our General and Technical section you will find on the front page we have all Rotary Manuals from Vintage to RX-8

so ive tried fresh fuel, fuel filter and also replaced the fuel with a walbro 255 as i had one on my shelf ive been meaning to fit for ages.

still no luck, who is the best place to take one of these to which would be able to sort our at least locate the problem?

any other ideas would be awesome, car is going in for some welding this weekend and cage fitted so after that its winter proofing it and trying to get it back to running perfect

Tim is extremely knowledgeable on all Mazda rotaries and is probably your closest specialist.
