someone please help my protege is dying

[nightmaresk8r45]

ive never used this forum b4 and im getting desperate

i bought my MSP in november from an older guy who was the original owner

i only paid 3500 dollars for it

BUT

it has never ran right since the day i got it

it stutters and bucks and hesitates

its dirt slow

and EVERY so often it will run good for a liitttle but then goes back to s***

it has 138k

everything is NOW stock

i tried modding it but it just made things worse

it throws a "random cylinder misfire" code

when u rev the engine up and kick the pedal i spit flames...it sounds like gunshots tho its so loud

i replaced the coil packs

spark plugs

spark plug wires

egr valve

timing belt water pump etc

and it still does run any better

i also changed this VICS sensor..stil no better

i CANNOT fix this car idk whats wrong with it..neither does mazda or any of my friends

the car legit sucks

it makes boost and everythhing

but it goes NO WHERE ..

u hardly feel the turbo.

the whole car sounds like it struggles..id say its a 16 second car at best

help me fix this thing

Ever do a compression test?

 

[03.5BlueMSP]

ever look at the stock exhaust manifold? you may have a giant crack..

 

[sublyminull]

Where are you located at? if your in or around kansas city missouri i'd be willing to help you take a look at it.

But yes start checking through all the threads in this forum that have similar problems. it might be a cracked exhaust mani. And taking it to the mazda dealership and having it diagnosed if you can't find whats wrong would be a great investment. gives you a starting point.

Dumb question, but are you filling up with 93 octane? We had a guy with similar issues that was cheaping out and using 87. He switched and the car ran fine...

 

[nightmaresk8r45]

i use 93 octane evveryday

my exhaust manifold is okayy

i sorta think its my fuel pump?? im not sure..

OR my exhaust manifold has a crack underneither it??

but i doubt this because once 2 of the bolts fell off and my exhaust mani leaked and u could hear it

it still sounds quite so i doubt its leaking anywhere

im really starting to hate this car...its been 8 months and it still runs terrible :[[[[[

 

[nightmaresk8r45]

oh yeah and my compression WAS fine when i bought the car...but from it shooting flames all the time everyone tells me is gonna ruin my compp. so idk if its still good anymore

 

[shane02pro5]

Is it possible your timing is off? What does it do just cruising and not under hard accelleration. How is the idle? Also does it have starting problems?

 

[Outlawstar98]

What's your vac pressure, and how much boost is it showing?

 

[slavrenz]

What's your vac pressure, and how much boost is it showing?

+1. Maybe there's a big vac leak?

 

[bazooka joe]

didn't notice o2 sensors?

 

[nightmaresk8r45]
