Hi can any one help me please, for a while now my revs have been staying up while changing gear at low revs and when coming to a stop at traffic lights the car ticks over at 1500 for a short while then jump back down to normal tick over, it is very anoying.

Has anyone else experienced this, could it be the maf?

my car's a 96 wrx impreza.

Thanks, Dan.

 

I had something similar on my old cavalier, it was a leaking vacuum hose meaning that there was a greater airflow into the throttle body. It's a simple check that won't cost anything

 

Thanks I will check all vacume lines.

 

i had this problem when my speedo broke and it went into "limp mode" with a 4.5k limiter...

 

Sounds like the IACV may want a spray out with carb cleaner tbh

 

i had exactly then same problem about a month ago and it did it for abbout 6 months. i changed the induction kit and it cured it

 

Thanks for your reply's
