An AC compressor puts a big strain on an engine when it's engaged. This is especially the case with low horse power 4-cylinder engines. What makes matters worse are high mileage engines which are in poor running condition. I experienced this with a Saab I used to have. I could only run the AC when I was moving at highway speeds. Otherwise it was too much ...

You might expect about 19.6 km/l (all things perfect, maximum efficiency), but 14.5 km/l highway to 11.5 km/l (city) is realistic if fuel/ignition/engine are in excellent condition and the tires are correctly inflated; those numbers are original factory spec. There are physical limits to the efficiency one might expect from any given car due to weight, wind ...

As I said previously, a set of Osram bulbs would help a lot. Further to that, your headlights may just need a nice polish. Some people try to get real fancy with products and methods, but what it really comes down to is that you need to use various grades of sandpaper (from rough to very fine) and finish off with rubbing compound and/or liquid polish (I use ...

It's an engine control module, and it's not the problem. AKA "computer". However, "computers" usally get blamed for any electrical problem, first because old-guard mechanics hate the things and long for the simple old days, and second because their functionality is fairly opaque and hard to analyze/test, and third, because resetting a computer often clears ...

Assuming this problem is with the vehicle stationary and at idle (question states 800-1000 RPM), this usually happens due to one of the following reasons: A leak in the air intake tract/manifold that allows unmetered air in One could detect the presence of leaks through a smoke test. Compressed air and soapy water works as well. A faulty idle air control ...

It is worth making sure that the bulbs are getting their full voltage - Halogen lamps drop off in brightness significantly as voltage drops. Many cars of that age didn't have relayed headlamps, and so as the wiring has aged, it's resistance has increased, and the performance of the headlamps will suffer - fitting relays close to the lamps with new, good ...

I had similar problem with my car too. During the 60 000 km check my mehcanic said they had to replace the "AC belt tensioner" because it was in bad condition. It didn't cost too much, worth a try. That 'click' sound after switching on the AC means that the AC clutch engaged and yes, it could be a bit noisy and it cause a strain for low powered cars. It's ...
