not sure what forum this should be in...
i just installed a FT 6" LA kit on my '00 XJ this last week and upon completion, started it up and it runs like crap. the exhaust pipe between the cat and muffler started to glow red after about 15min. of runtime. i took the cat out and now there is just a straight pipe. the vibration has gone down a lot, but something is still wrong. the engine seems to run worse as it warms up. i took electrical connections off the injectors one by one at idle to see it i could find wich ones may be the culprit. the #1 and 6 injectors had no effect on idle speed. #3 may also be bad but still not sure. i also noticed a small crack by one of the coils on the rail, which wasn't there when i put new plugs in around 10K ago. it's a 4.0L w/ 70k on it. any advice would be great.
i am also wondering as to where the best place to buy oem ignition parts for it would be, as opposed to going to the dealership.
