Any idea's, engine starts up with revs at 2000, and when it get up to temp, the revs start hunting. Water levels OK, but water line to iac are cold? Rest are hot
Other issue, timing looks out 14 degs?
Any pointers

Early 24v issues
Re: Early 24v issues
I'd ask the same question as Trev as I had that with my 16v on a couple of occasions.

Re: Early 24v issues
Yes the manifold has been off doing the rocker gaskets , we did try and squeeze the main hoses to see if we could get more air out but they were a bit hot, the heater hoses get hot as well, I'm going to loosen the front hose pipe to the throttle body to see is water comes out.
Re: Early 24v issues
I connected the garden hose to the bottom heater pipe. That fixed it! It went from South Georgia to tropical island paradise.brookie66J wrote: ↑Wed May 19, 2021 11:05 pmYes the manifold has been off doing the rocker gaskets , we did try and squeeze the main hoses to see if we could get more air out but they were a bit hot, the heater hoses get hot as well, I'm going to loosen the front hose pipe to the throttle body to see is water comes out.

Re: Early 24v issues
If the pipes to the IAC are cold then it could be a blockage on the EGR Valve as the IAC water lines run though this.
The EGR has a steel pipe that runs round it and this can corrode and get blocked stopping flow in and out of the IAC.
Also check where the IAC pipe joins the Engine block as this is a steel pipe that can also block up.
You need to get these hot so the IAC is fully open or the Idle will be all over the place
