Hi Guys
Yesterday when I was off-roading after putting a bit more pressure to the engine air bleeding T valve on top of the engine broke on the small water hose and started steaming. I have added water and connected the hose directly back to the t-housing as a quick repair and drove the car for about 10 miles to the dealer. Every time when I see the engine temperature rising I have turned the engine off and let the car roll gear in N to keep the engine cooler. (Stupid idea)
Service guys replace the top house and told me that the thermostat was also gone. So they have replaced the t with housing as well.
However this morning when I went to collect the car there was misfire from 2 cylinder and rough idle.
Since the further diagnostics and repairs would cost me lots I have taken it to a private garage.
When I drove the car I could see there was a bit of loss off power and it was only rough running when idling.

Private garage guys checked the coils and looked like were firing ok.
So I left the car again for further investigation.
I wanted to ask you what else might have gone wrong based on your experience?

Any advise would be highly appreciated

I've had issues with the thermostat that led to rough idle and CEL and REP. No misfire though....also the MAF leads to that. I also carry one of those bleeder T's with me...cheap part!

 

I have seen several instances of coils failing following an overheat situation. When I see this, I always suggest replacement of all 8, I've had a few times with replacing one or two, and needing to replace a few others a week or so later.
