Hya,

When I first got the wrx import a week ago it didnt smoke now it has black/grey smoke coming out, I did put a little bit of 97 ron petrol in then relised and put in v-power straight away, it needs new exhaust manifold gaskets could this be the problem?

As well as the smoke its not idleing propaly at all and when I rev it it stuggles at 2k for a while.

I was told to reset the ecu due to putting the wrong octane in, it mucks with the ecu I was told what do you guys think

Thanks mark

 

did you put oil in it ?? grey smoke is oil....hope it aint the turbo seals...97 ron wouldnt have done this...

 

It's definately not because of the 97 ron, something else is the cause.

 

hya,

cheers for the advice, it aint the turbo seals I have had turbos before and blue smoke is turbo or valve seals, blake smoke is unburnt fuel as far as I know anyway.

Do you think its worth resetting the ecu?

thanks mark

 

Hya,

Has anybody else got any ideas, I thought it could be down to the leaky exhaust manifold gaskets as the lamba sensor wont get a true reading.

What do you guys think.

thanks mark

 

any cel codes ?? connect the two black wires under the steering column and check codes...might be the maf thats tooshed !!

 

Ok mate thanks for advice.

cheers mark

 

Have you made sure all the intercooler pipes are fine and no little leaks? Does she struggle through the rev range or just at 2k? Check the MAF by plugging it out when shes running.The Lamda is a strange thing.Think it works through signals rather than an actual sensor,like an oil temp gauge would.Worth checking out though.

 

Check out this info:
Lambda sensors / exhaust oxygen sensors

 

Cheers mate you are a true gent all finguers point to the lambda sensor now great help.

thanks mark

 

hya,

what motor are you running mate, is it an impreza saloon or wagon mate, just wondered.

mark

 

A nice big STi Wagon with plenty of room in the back for the ladies

 

lol

what tou running mate standard power or more, I bet you shock alot of people in the sti wagon.

mark

 

To be honest dude,i've never got a proper dice with anyone in her yet and i have her over a year now
Just a little more than standard at the moment.Waiting to get a Power FC in Oct with a few more goodies in place before that happens. Not going more than 330 > 340bhp cause my engine will start to bubble!!!

 

lol

340bhp is enough mate still fast as hell you will suprise a few people lol

mark

 

hi there mate i have a spare lambda sensor going cheap if you need one where abouts are ya if your anywhere near me you could always try it first see if it cures the problem

 

Hya mate,

I live in thornaby near middlesbrough thanks for the offer I will fit the manifold gaskets mate and if its still running like **** I will pm you mate.

cheers mark
