Question

My D16W4 aerodeck has developed a few issues recently, considerable loss of power at higher rpm all of a sudden which has only gotten worse, and stalling when the brakes are applied hard at low speeds as well as just driving it gently and then rolling to a stop the idle drops hard and almost cuts out or it just cuys out, it overheated yesterday morning and cut out in slow traffic after about 10 minutes at 60 on the dual carriageway, limped it back home once it had cooled down and didnt seem to overheat after but I havent driven it since except just to try and diagnose whether the stalling at low speeds and braking is a vacuum leak on the brake booster, booster vac line or master cylinder even but the booster seems to be working alright and the vac line from the intake still has vacuum so im guessing its not the line or the check valve inside.

 

Would be great to determine if these issue are fixable without too much headache (hopefully not headgasket causing the overheating).

 

Any help at all is appreciated, I really would love to keep the car on the road and usable as its only on 128k miles and if its too much of a headache i'll have to shelf it and use it for a more serious project (maybe a k swap)

Sorry for the late reply mate. Does the car run hot after a certain amount of time/miles every time. Does the temp gauge sit at normal temp then suddenly go high, or does it just keep rising once the car is started. Alternatively, does the temp sit below where its meant to but the engine overheats? Has the thermostat been changed recently? 

I'd suspect either the thermostat is duff or the coolant system needs bled. Cheapest fix is changing the thermostat so would always start there. These have been known to be a pig to bleed sometimes!

 

The other fault I'm not too sure on, you've mentioned a few of the possibles already so concentrate on those first and work from there. Faults can be a mare to diagnose because these aren't the usual OBD2 so can't plug in the diagnostic to check what the fault is. I'm sure it will be something simple as the D series engines are pretty unburstable. 

You could check the oil filler cap, see if there's any "mayo" on it which would deffo indicate failed HG, but highly doubt it on one of these.

Hopefully someone will jump in with more answers on that fault for you.
