Misfire, Headgasket or The End??
Good morning…
I have posted in the intro but was very kindly guided here for any help.
My 2.5 Sport S Type Auto is currently misfiring badly, coolant needs topping up daily, Red light for (Limited performance ) flashes up, The anti lock (skid) light comes up saying it's not working anymore….so is this the end??? I have no idea what is happening but I don't think it will go on much longer. I would appreciate some advice or guidance as not sure how to keep costs down on this one. Thank you

Don't panic. It's unlikely to be terminal but does need attention.
+1 on OBD codes - cheap tool $10-20.
Get one with "live data" so you can read LTFTs (long term fuel trims) as they'll show whether it's an air leak / only one bank / etc.
Thread in General Tech but elm327 is great.
Commonly it'll be misfires due to coil(s) or an air leak. Possibly damp or other cause.

Thank you
Thank you all for your replies. I do know that when it had a test it said there was oil in coolant and it needed a new head gasket. The problem is cylinder 5…but the problem is getting worse. I need an understanding of how much this will cost, or whether it is cheaper to get another car?!!

if it is the head gasket (and i hope its not) and you are thinking of scrapping it, as a last resort you might want to try steel seal (or something similar) (a pour in head gasket sealer).
Now before everyone jumps all over me, i'm only suggesting this as a last resort, and the reason i'm suggesting it is, a friend of mine was going to scrap a van for the same reason, someone suggested he try this, he did, and got 50,000 trouble free miles from the engine, before the gearbox gave out.
