I have been driving in the high way and all of a sudden the engine pressure gauge started to drop slightly and I started to feel engine hesitation very slightly, when I stop the car and start to accelerate it drives very slow it feel as I am having an cylinder misfire.

I drove around 25 KM to the nest mechanic next day I explained to them everything and they said we drive your car for one hour and we didn't find anything suspicious and they have me extended period to report to them if inexperience the problem again...

Now that worries me i might have some problem in the future...

Have you experienced any similar problems?

Note: There were no error codes at all, its a 5 cylinder 2008 hummer and drove it for 118,000 KM engine tuned up a month ago.

Could be plugs, wires, coil pack, throttle body needing cleaned, etc.

Well I did engine tune up and they replaced sparking plugs, engine filter and, cleaned engine coils and other tune up stuff thatbi do not know about... like they added some substance to clean fuel tank...
