Problem... ECU or Boost?

Check the snugness of all intake/intercooler piping junctions.
Checklist:
1) Intake to turbo
2) Turbo compressor to hot IC pipe
3) hot IC pipe to IC
4) IC to cold pipe
5) cold pipe to TB

As far as the "lighting up like a christmas tree", this is just what happens when your engine stalls, just like when you first put your keys in to start the engine.

I tighten them all last saturday and it didn't changed anything.
 
You may also check the manifold to turbo gasket is leaking, start the car, with your hand close to the division where the gasket is placed, accelerate the car a few times, if its too hot, use a hose and your ear.

I'm gonna tell them to check for leaks...

Could a jammed cat do this?
Funny thing is that there is no check engine light so they have no lead at all.

Well, extreme situations calls for extreme mesures!!

Next monday a bran new ECU is gonna be in the car (boom07)
They will also check the turbo mainfold for leaks and the cats for jams...

Plugged cat will be a constant problem.
Yeah I know, I was planning to get rid of the cats in late spring/early summer. But that is IF they can get the car running before then. What happens if a dealer can't fix a problem? They call a "super tech" higher in hierarchy?

they will offer you a NEON
 
Well I was expecting it: the new ECU didn't do s***.

Dealer is now checking for leaks or bottlenecked cat.

do you get to keep the old ECU? (naughty)
Lol you know dealers, if the part got replaced and that didn't solved the problem they return it back :(

I'm giving them until friday then I'm sending an email directly to Mazda Canada so one of their "super tech" gets working on my car.
I'm starting to be realy pissed. I'm going to pay my car payment for the full month but I will only have it for half of it if it or less if they don't find the problem by friday.

(bang)
 
at least the dealership is helpful. i'm sure the problem will get solved, but if they have the car for a long time, and attempt to fix the same problem more than once, look up the local laws regarding lemon cars. unless you don't care about the waiting. wondering why the dealership changed the ecu first before checking for leaks or the cat, weird.
 
I just called them. They told me that the Instructor in chief of Mazda Canada is on my case. He sent them a new coldpipe to try and see if it solves the problem. Belive me if it's the plastic pipes that caused the problem I'm gonna put some hardpipes in there as soon as I get my car back!

While they wait for that, I told them to hook off my boost gauge from the vaccum line... can't belive I'm looking for a solution there!
 
The new cold pipe is because they found the vacuum/boost leak. Probably the nipple for the bpv was loose/cracked.
