Sounds symptomatic of failing coil(s)
Are these coil on plug?

Damn missed it again

No dice, after about 5km of driving a mix of 50kph and a short stint on motorway at 100, check engine light comes on and it starts to idle high again.
Once its been turned off, when i start again the CEL is off but high idle remains.
Time to start pulling the codes i guess, open to other suggestions

Cheers, I pulled the existing and gave it a clean, which had an immediate impact in fixing the idle issue for 24 hours, then it proceeded to do all kinds of weird idle 'control' that it hadnt been doing previously followed by some pretty consistent running. When it "fixed" it, I was hoping it was a ...

Only reason for coolant circulation is defrosting of throttle body IIRC, you can block/bypass/whatever

OK so cleaning the IACV seemed to help a bit, but then i was getting CEL, and sometimes revs at idle in neutral or park would be pushing 2000rpm, and in D its at nearly 1200rpm and fighting the stall of the torque converter. I found another IACV and that seemed to help for a few kms of driving but ...

I have a couple of spare tps's. I have a feeling the rotary iacv may have been full of crap so split that and gave it a clean out. Will see how it goes when its all back together

seems i can only get it as low as 0.54V and at WOT its 3.83V

Anyone know how interchangeable toyota tps's are between models (ie screws and plugs)?

nope, plugged and played, so will show my ignorance, how do I do so?

Presumably done by adjusting the stopper screw on throttle body - where do I take voltage from?

Ok so my spare tps/throttle fixed that. Unplugging the old one dodnt make a change to symptoms, replaced and problem went away. Drove for a bit now have vacuum leak symptoms. Idling rough and stalls when i put into gear. Thought it was brake vac hose but no. Seems to be idling and running lean

Will ...

they are quasi obdii iirc, nah havent pulled codes yet

OK so this new problem:

Caldina was running sweet, then went to go for wof recheck and it is running a bit shit
Hesitation when in gear (ie has load), or when in neutral and go straight to WOT (foot straight to floor). Part throttle through rev range seems fine in neutral (can gradually open ...

Cheers, has been holding but I will investigate

Outcome of wof check was ABS sensor dead and steering felt like UJ was binding
Replaced with a sensor from zebra - fault cleared
Fiddled with steering column and readjusted alignment a little - turns smooth

Fanged the shit out of it on saturday to ...

lol nope, everything came apart again ok though, leaks were a cone gasket not seating right and where the 2-1 flange connected to the fab'd system under floor, the alignment of the faces wasnt great so stuck a crush type gasket in and that sorted it.

Two problems left I think, radiator drain screw ...

Starting like a champ now, but suffering with an exhaust leak at header end will have to recheck gaskets

Well got one start, but forgot how loud this thing is (i have put st202 ssIII headers on to delete the cats in manifold abortions. I think the crank position sensor wires were shorting at least thats the last thing i $&#$% with/tidied before cranking. Hopefully can sort tomorrow

oh jeah

Hey guys, have had the engine out of the wife's caldina doing a bunch of seals and other bits and pieces as it decided to turn british on me.
Have got the engine back in and its cranking but wont fire.

I seem to get pressure at the fuel filter (when i crack the banjo bolt it squirts out but not a ...

Hey, so I managed to smash the plug off the solenoid on the wife's caldina when putting engine back in Does anyone know if the solenoids are engine specific? I can get new from toyota ok but its also easier and cheaper to get a hold of different engines solenoid valves, ie 2jz 1zz etc

you mean on the 2-1 section? I don't, was thinking of just getting a thread welded into one of the cylinders extractors
