Hi,

My car was having a misfire. I had changed the four fuel injector, power plugs, software update but nothing helped.

Still misfiring and jumping RPMs. Water throwing from cylinder when the engine is cold. Every time I start the car in the morning it irritates me. Every morning i need to warm up the engine at least 5 to 7 minutes with RPMs at 1,000 to 1,200 for couple minutes after the Engine reaction is no problem at all.

So far, several mechanics have checked the car no one produces a long-term resolution. Please advise.

When you say water do you mean coolant? Can you upload a short video of the problem so I can see what's going on? Also, we should do a compression test to see if the engine is in good shape.
