Hi
I have a my93wrx with decat ,apexi induction kit, blitz vta and apexi backbox when I accelerate hard in 1st and 2nd then have to slow down quickly (braking) the revs dip down extremely low or actually stall is this a problem with the vta spring going slack.
Most of the various sensors have been replaced (including the maf) and it was running fine.
Is the hot weather going to cause problems?
I know some people will say get rid of the vta because its chav but i would rather not have to spend money replacing it.

Thanks in advance

Paul
