Swapped head, idles at 1.8k HOT, drops once in gear?

[oscaryu1]

Recently swapped a new cylinder into the camry (old one was overheated, dropped some valve seatS). Not sure what I'm doing wrong...

After "warming" up the car, everything under the hood seems to be VERY hot. Can hear gurgling around where the coolant temp sensor is. At the "warm" stage, the ECT measures 180 ohms... a bit outside the normal range of "250-300ohms at operating temp". Both fans will eventually come on, and the temperature gauge is always in the middle (normal).

When started COLD, idles at 1.5k, and slowly climbs to a tad below 2k. Accelerates fine, and once in gear it immidiately drops down to 1k RPM, and jumps right back up to 2k in neutral or park. When AC is on, drops to 1.5k everytime.

No CEL, no engine codes (checked).... could it be because I'm using VERY cold spark plugs? (BKR9EIX)? Those were all I had at the time and I just put them in. Started/ran fine... dunno if that would be the problem?

OBTW - Sprayed WD40 all around intake manifold top/back/flange area, no idle fluctuations. Air temperature sensor nozzle is broken off, not sure if that makes a difference (left it hanging in the engine bay... still plugged into harness though).

Your fine as long as you hear the coolant running on the head and the engine your fine. I did that to my 5sfe engine...engine got 300k miles on it so I put 160k miles from 5sfe 95 camry. I got the same problem when I drop it. Replace your thermostat, thermostat sensors and make straight positive wire to your radiator fan just the one side to ran it if in case the RADIATOR Fan is not firing too late. I mean too hot.

Is that head came from running car?

Is your radiator fan fire up when its too hot? As long as coolant running thru back and forth in the engine you be fine.....just keep the fan running if it got too hot....wire up the other fan separate to fire it up when you want it.

sounds like a serious vacuum leak perhaps?
do you hear loud hissing around engine somewhere? are all vacuum hoses plugged in correctly and everything matches up?

Check the Iac valve. Mine did the same thing.

I only did the VCV when I can't figure it out. As long as its not running loppy. Does the car shakes when you put it on gear?

[deejayphilo]

I mean VSV ...sorry......that sound your saying is the intake manifold gasket. Somebody told me if you buy aftermarket intake manifold gasket its not as perfect as factory...

[oscaryu1]

Sprayed WD40 straight at the intake manifold flange, no difference in RPMs. No sucking sound. IAC worked before the cylinder swap... cylinder was new resurfaced/rebuilt.

Try unplugging the connector to the iacv and see if there is a difference.

I think you have more on spark problem rather than on vacuum...
