Hi everyone, so we have an issue with our Vitara since Saturday, actually the issues started about a week before, but Saturday was when it really got so bad that I couldn't get it started. Sounds like she is running on 1 cylinder on cold start, she eventually starts running on full cylinders the warmer she gets and needless to say she is using a lot of fuel. Black carbon emissions spitting out of the exhaust. We have changed all spark plugs and cables to distributor, we have cleaned the carb (not the original as we had similar issues last year and replace the carb) She is regularly serviced with all new filters, etc. So my question is, where should we start looking to solve this?
