I have an 03 disco 2. I replaced the fuel injectors but now I have a misfire on cylinders 3, 4 and 6. And the exhaust smells like its running super rich. Anyone know what might have caused this? I triple checked all electrical connections before everything was buttoned up. I should probably note, there were no misfiring cylinders prior to replacing the injectors. I should also probably note that it barely wants to start and idles extremely rough, but when driving around it drives like there it's nothing at all wrong with it and super smooth. Thanks in advance.

 

For anyone who may also he having this issue I think I may have found what the cause is. When I buttoned everything up I had a few plug wires touching the secondary air injection canisters lines that tie into the heads, and they got a little singed. I will change the plug wires and post the results.

 

Well it wasn't the plug wires. Installed new ones. Runs great when it's cold then runs extremely rough at idle when warm, wants to die but once I get moving the SES light stops flashing and she drives fine. Anything standing out to anyone? I'm stumped. New coil pack?
