Have a 1990 4runner with the 3vze and have issues with the idle.
It seems to struggle to keep the revs up often after stopping at traffic lights, or when turning with the wheel at full lock.
It also has a bit of a stutter at around 2000rpm in 4th gear, is quite jerky.
Replaced so far:
Dizzy cap and rotor
Plugs
Leads
2 x Solenoids under inlet manifold on right side of vehicle(they were missing when i bought the truck)
Other things ive checked:
Throttle body removed, cleaned and replaced
Idle screw changed but does nothing
Vacuum lines checked (1 is open not sure why or what its for)
I was talking to my auto electrician today when i got my AC regassed, and he says there is a sucking sound coming from the EGR thingy on the right hand side of the engine which shouldnt be there.
This is it:
There are some holes in the bottom of it that are constantly sucking in fresh air and its quite loud.
Had someone else mention that it might be only running on 5 cylinders?
Anyone have any idea on what mite be causing my screwed up idle?
Cheers
