Car Doctor: Why does the engine just cut off?

I have a Toyota Carina II built in 1991, a 2.0 automatic. The engine cuts off but judders first as if starved of fuel but the tank is at least half full. It will re-start eventually. I've checked all electrical and fuel connections and fitted a new air filter. But I can't locate a fuel filter, any ideas?

With thanks to the Toyota technical department, the fuel filter should be located in the engine on the right-hand bulkhead. As for what could cause these symptoms, it may be worth inspecting the carburettor for contamination and inspect the anti-run solenoid for correct operation.

My car always starts, whatever the weather, the problem is when I stop at a junction. Firstly the revs drop down, all the warning lights come on and then the revs climb again. Sometimes it stalls and I have the same problems when turning the steering wheel on full lock. There are other minor electrical glitches. I did get my local garage to clean out the throttle body but I'm still stalling.

To an electrical specialist it sounds like a problem with the wiring harness. There could be a loose wire. A garage that can fault code read your electrical system may be the easiest answer. Alternatively the idle could be affected by a faulty control valve, although when the garage cleaned the throttle body they should have checked it.

My car is generally very quiet, but I have noticed that at motorway speeds there is a lot of noise from around the windscreen. I have looked at the seal and it seems fine to me.

The most obvious cause would be the bonding agent on the glass itself. This can wear away after several years. However, if your windscreen was replaced in the last few years it may not have been sealed properly. In that case you will need a specialist to remove, clean and re-fit it. If you have a sunroof it will probably be worth looking at the seals, just in case the noise is coming from there.
