not long had my wagon back after a rebuild,the problem is when accelerating (not hard) the car seems to surge\pluse. i can seem to think what might be causing it any ideas.


my99 wagon magnex, backbox, vf28 turbo, and induction kit

 

mines doing that at the minute, gonna try a MAF sensor and see if it makes a difference

 

mines just had that though in the rebuild,i suppose it could be faulty may get to look at the 02 sensor as well.
i just wondered if it was due to the turbo change?

 

is it a uk car? if it is has it been re-mapped for the new turbo?

 

yes it a uk.
no i have not had a remap, this is what i was thinking of for my next job.just trying to recover from puting a new engine in after 11 days ownership.
i know it is a commonish thing on my99 but i thought it was when the engine was cold?

 

Curiously enough, my bog standard MY02 WRX does this on 95 RON unleaded, but not 97 or Optimax. Does it definitely have the right fuel grade in?

 

since it blew it has had nothing but optimax in it.how much would a remap cost?

 

did you discover why it blew? if not could this pulsing be a sympton of the same problem and its going to fail again if you dont drive gently until you find the reason? Just a thought.

 

Similar here on MY97 with full de-cat and dawes.

Hunts around 2.5-3k put pulls OK when floored.

Will check ecu over the w/e along with other bits and bobs!!

 

thats why i posted about m8,(i can not afford another lump until next month) i wanted a bit of info on thing to suggest when i take it back sturday

 

i can not really say if it is ok when flooring it as i am just finishing running it in,but it does seem ok if i change down and acellerate.it seems to happen if i use a steady gain in speed like on the motorway.

 

It's probably fed up of running in
Redline it
