Hi I am a returning member to this forum. I am currently in my surgery residency here in Gainesville FL and due to the limited amount of time I spend outside of the hospital have sadly neglected my '03 Disco since moving here 3 years ago. My check engine light came on approx 1 month ago but she was running fine... Then 1 week ago there was a really rough idle and intermittent acceleration jumps on the road. 2 days ago the coolant hose blew out right before the connection to the radiator. I have replaced the hose segment and that seems to be OK now but the car is still running very poorly and I hear a gurgling sound which I assume is the coolant reservior when I hit the accelerator. I went to go get the codes today, here they go P0300, P0301, P0303, P0304, P0305, P0307, P0118, P0171, P1319, P1412, P1300.
I would really like to try and fix whatever is wrong myself (if possible) but I really need some guidance/help. If anyone can assist me in any way it would be greatly appreciated, (surgery residency doesn't pay much and I don't want to let go of my Disco!!)

 

That's a whole lot of misfires and I think a temp sensor from low coolant probably. Looks like your running on cyl 2 and 8. Check the plugs and wires, bleed the coolant system and clear the codes. Then see what codes come back, hopefully not all of them.

 

Hi thanks for the quick reply, I topped off the coolant from the engine reservoir when my hose blew out but was wondering if there was a better way of flushing the system. Also, have you changed the plugs on a disco? I want to change them myself but I have read mixed reviews on how easy this is to do. I definitely am game to change them on my own if you can give me some instructions.
