Hello everyone. I just bought a 03 Disco HSE yesterday, and as soon as I pull it off the lot the check engine light comes on. I take it back to the dealer and he runs a check and says #4 cyl is misfiring. Is this a common problem? Possible reasons for misfire? Any help would be greatly appreciated, since I come from having a Mustang Mach I and a Lightning, these Discos are Mysterious and strange to me. Thanks

 

How many miles on your truck, did you check to see if your engine is one of the ones on Rovers list of possible oil pump/engine failures?
Any misfire can happen and most likely the truck hasn't been tuned and had the plug wires replaced.

 

108K miles, and I didn't even know about an engine list with possible problems. Where could I find that?

 

Well, at your mileage, you will probably be OK, call a local Dealer service dept with your vin to verify.
How mechanical are you, will you be doing the past do service?

 

I just printed off your high mileage service list, and I'll probably be tackling some of it this weekend. I just don't know if it's just a plug, wires, coil pack, or if it is something major that these vehicles are known to have problems with. So I thought I would ask since I know little about these vehicles.
