    Stalling corona

    Toyota Toyota Advice Toyota Corona Toyota Corona Advice Toyota Corona 1980
    I own a 1980 Toyota Corona. It has done 221,000km, and it is in good condition. However it idles roughly and stalls when I start it and back it out of the garage every morning. Once it's warmed up it seems fine. I was wondering if the problem was caused by the ethanol in the LRP petrol I use?

    There were reports from Western Australia of a build-up of deposits on the spark plugs of engines running on LRP and which were driven only short distances. The deposit was blamed for poor starting and running, so it's worth checking your plugs for abnormal build-up of deposits. Clean the plugs before reinstalling them in the engine. If there is an unusual build-up that could be causing the problem, consider changing to a higher heat range spark plug that would help burn off the deposits. While there is a chance the problem is caused by the LRP you use, it's more likely to be a problem with the engine itself, so check the carburettor to ensure the automatic choke is operating correctly, and check the ignition timing, points and set them to specification. Also check for signs of intake manifold leakage.
