Hi Ken,
When I start my car in the morning (cold start) the check engine light flashes and car rumbles. But it drives fine with an occasional jerk that feels like gear shift on a manual and the rpm doesn’t go above 4,000 RPMs whenever the check engine light flashes. After about 3-5 minutes, I restart my car and the rumbling fades out and everything feels normal. Engine light now stays on. Since the car functions fine. Now I let the car idle in the morning for 5 minutes and then start driving. The same thing happens in the afternoon.
In summary the check engine light flashes for a few minutes during a cold start. If I stop the car after driving for 10 minutes and restart it, there is no such problem. I suspect this is a rare problem. I have taken my car to several garages. No one diagnosed the actual problem. Coils and spark plugs have been changed recently, still there’s no end to this problem. Please help me out I'm finding a solution for 2 months. Please do the needful.
