I drove about 20 min at 40-50 mph to the emissions facility. Shut off the engine for about 15 minutes. Restarted the car and waited for about 10 minutes. Rev the engine fat 2000 rpm for about 5 min before it was my tunr to be tested. Would these conditions result in these high numbers? Should I have warmed up the cat more?

How do I adjust the timing? I have the Haynes manual and the cd manuals. Are the instructions there? Would changing the spark plugs, air filter, and adding fuel injection cleaner help?
