Our engine hasn't been running right for a few months.
Generally speaking, accelerating with full throttle is fine, but when accelerating normally, the engine will often cut out at 3,000rpm and reaquire very light throttle to get past 3,000.
ECU Error codes said MAP sensor/ vacuum sensor so I shelled out for a new MAP sensor, no difference.
I replaced all vacuum lines to the Map & vacuum sensors. no difference.
I checked the turbo and couldn't find anything wrong.
Put a boost gauge on it and found that it was overboosting at 15psi. This will cause the ECU to cut fuel, so finally I know what's happening.
And with that question, it dawns on me that if the actuator wasn't opening the wastegate, the turbo would overboost.
So I checked the linkages again, all intact. Lubed them with some WD40, no difference.
Checked movement by hand, it opens the wastegate. I check the vacuum lines and realise, the line off the actuator is going to atmosphere instead of boost !!!
Plugged it back in and we're back in business with a smoothly running 4EFTE Sera....
Until the hose blows off again while the wife is doing the test drive. It cut twice then backfired and blew flames out the exhaust!!
I'm glad I upgraded the Cat to a 200cpi metal one
So now with 50cents of new vacuum tubing between compressor and actuator, it's fixed properly.
Time & money spent was a lot more than 50cents and 10 minutes of struggling to get a 20cm hand into a 10cm gap between pipes, radiator, manifold & turbo.
But the flames were cool. !

We decided to risk driving it 15 minutes to home - stopping a couple of times to fill up water and let engine cool down along the way.
Pulled things apart and here's what I found:
A new thermostat housing would be a good idea. Toyota "only" want $135 which isn't too bad, but none are in stock. It will take a week to make one and 2 weeks to ship it to me.
So instead I grabbed some JB Weld and have applied it over the holes and around the pipe.
Once it's set (15 - 24 hours) I'll give the cooling system a great big flush, reassemble engine and put a new hose all the way along that pipe so it covers the JB Weld where the holes were. Fingers crossed it will be reliable.

I've also flushed the radiator, heater matrix and engine with hose pressure water.
Next is reassemble, then a checmical flush and finally fresh coolant with rust inhibitor.

It's running, not leaking and ready for Toyotafest next week.

I had been having intermittent starter motor issues - sometimes it just wouldn't start and seemed to be a heat issue.
I suspected the starter motor was in poorly condition, so lifted the car and removed the Starter. I pulled it apart and couldn't see anything wrong, but...
A replacement was over $400, so I contacted an auto electrician about a rebuild. He said, old cars like that often have insufficient wiring to the starter and experience voltage drop. He'd run an extra power cable with relay and it should be good.
So I did that myself and it's been 100%. touch wood.
Then I noticed the battery was not only leaking a little acid, but also swollen, so it's been replaced. Was only 3.5 years old
Then a few weeks ago, we went to a car show / chill out. Kids had fun in the sun & it was good to look at a lot of other cars in the "scene".
It seems air bag suspension is becoming popular with a new generation of enthusiasts, so I bought some new suspension for the Sera.
"XYZ" brand Coilovers - specifically for Starlets, but I believe it's compatible. I get to install it next week.
I was quite impressed by the retail packaging.
The plan is - rear shocks are at least 15 years old and need replacing. Fronts are probably 10 years old and now I get to customise the ride height, removing some of the excessive gap between tyre and wheel arch.
Perfect timing for Toyota Fest on October 3rd.
Anyone in Sydney on the day, come & say Hi at the Toyota Dealership, Victoria Ave, Castle Hill.

Steering travel looks OK, about a fingers gap to the brake hard line. Jacked it up and vertical travel doesn't get any closer.
I'm not happy that one of the bolt holes on the front struts is slotted (oval) - makes wheel alignment harder to get even, but otherwise I'm looking forward to having these on the road.
Tomorrow I'll put the wheels back on and see how it sits on the ground - I'm worried I may have it a bit too low - this is the static (unloaded) height difference of the struts:
Some might be interested - these XYZ coilovers weigh 5.5kg, my old spring & strut with a Koni insert weighs 6.6kg - only 1kg difference.
The same suspension swap in my old Mitsubishi Magna saved about 5kg per corner.
