Dear Angela @Foxtrot Oscar thanks for the advice. Yes I had only 1 stuck and 2 refusals. By the time I was trying to self recover from the refusal the car was already bogged down and @GauravSoni & @Yousef Alimadadi were already beside me and had started to give instructions and told me to stay back in the car. I had opened the door to come out and asses the situation when they already instructed to stay back in the car and follow their instructions in recovery.
Anyways I hope you remember I had some overheating issues some time before in a drive of yours and I had to exit. I had tried flushing the cooling system, subjected the car to innumerable computer diagnosis but was not able to eliminate the problem even though controlled it to some extent. The engine always used to cut the power when the RPM rises above a certain limit which resulted in some stucks before. I had to adjust my driving style and somehow managed all the drives till now. No mechanic was able to understand the phenomenon. They all even advised me to change the knock sensor and sort like that, even the engine mountings. Yesterday night I pin pointed the problem. All this started after I changed the spark plugs sometime before. Every time I tell the mechanics the same and they ignored it. I took out the spark plugs yesterday night and viola the culprit lay bare in front of me. 1 of the spark plugs installed was different from the rest. The spark plug number is same but spark plug is different. While 5 were platinum tipped and had blue markings. 1 was ordinary and had green markings but same number marked on it. This spark plug's heat range was different and was misfiring resulting in the engine laboring a lot under stress which made the engine overheat which led to loss of power and momentum. Its sometimes strange we can't even leave the car in a garage trusting the mechanic will take care of it as well as we do. The moment I replaced the different spark plug with a new one, the engine started to run smoother, the overall heat fell down drastically and the acceleration is linear. Hopefully I can drive smoothly during your next Saturday drive.
