Hi everyone i have a MY02 sti. i had it remapped my dynamix a few months ago as i had an engine rebuild done by api as the engine went pop. i havent drove the car for about 2 weeks but i just now started it up first things the car idols just over 1.2k rpm as david said it would due to upgraded pistons. so about 5 mins later the exhaust is still blowing out a gray smoke is this normal? then a few mins later the car idols then every few seconds it chuggs (dont know if i spelt that right lol) but i found it did this when on boost just before i took the car off the road any ideas if this is bad or is it ok?

thanks in advance

 

the chugging on idle could be the fans kicking in?

 

That's what I thought but they went running at the time also the car is kept in the garage so it's not in the cold

 

mines been sat for a couple of days because had the rocker cover off (the dreaded oil leak) once all back together started her up and got loads of white/grey smoke out the back, dont say headgaskets because i`ve just done them lol.
its just because its BLOODY freezin outside!!!
once warmed all back to normal, does yours clear when warm?

 

If you have a stainless steel exhaust I've heard the gather quite alot of condensation when cold. Mine is very smokey in the morning but once the engine warms up the smoke clears.

Hope that helps

yeh mines a stainless system too.

 

any car will give off steam when started from cold as they all trap moisture in the exhaust, if it ok when warm then nothing to worry about,

 

well i have left it running for 30mins and the smoke is all good but the engine is still making a chugging noise from inside the car so i lifted the bonnet up and looked at it and every few seconds you see the engine move when it makes the chugg noise anyone know what this is and if its something to worry about? also i put my foot down on the gas and moved the revs to a steady 2k rpm and it still chuggs? any ideas whould be good as i dont really want another rebuild as i have only covered 2562 on this engine.

 

mine does it too mate, once ive started driving it clears and runs perfect

 

ok thats good to hear the only reason being is i have never left my car off the road for no longer then a week but ive now taking it off winter. so how would you make sure the cra is ok just keep starting it up once a week or every other week?

 

If you are worried, surely your FIRST point of call would be Duncan, at Dynamix? An extremely well-respected mapper, and a nice guy.

 

well i wanted to no if something like this has happend to anyone else on here so i can a bit more info on what could be causing it. but you are right about contacting him but as stated i just wanted a little bit of advice from you guys on here as some of you really know what your taking about.

 

Some of us do...........but very few know more than an experienced mapper and internet diagnosis is poor at best..........

 

I am up in Norwich on Thursday if you want me to take a peek ?

 

hi duncan what time will you be in norwich as im only at home till 12 as have work at 2pm. but the car is sorn so i cant take it to far would you still be able to give it a quick look over?
