ive got a friend that called me a minute ago and said his 05 lly has started acting wierd. he said at about 1200 rpms and above it goes to smokin real bad. like its got a chip on it, but it doesnt. he said its shifting real hard and draggin the shifts out to redline before it shifts. its got 96k on it, fuel filter was changed about 5k ago, had the injector harness fixed twice now. and said its not throwing any codes. any ideas? thanks
