My 2zzge seems to not be its old self anymore. Its always had a slight miss at idle, but these days it feels extremely sluggish from about 1000-2500rpm.
When engine braking down a hill I have got the car to back fire before quite loudly too.
The other thing i've noticed is that the transition to LIFT doesn't seem to be noticable at all, it used to be an ON and OFF thing, but these days it just seems like a continuation of the revs (while I can JUST notice an increase)
I'm wondering if maybe one lift bolt (or maybe both) has broken?
I was wondering what might be causing the misfire (rough idle). At one stage at the lights it felt like it was going to stall (went to about 400-500rpm)
