2003 Roush Running slightly rough, and really slow 1/4 times
Hi
Ive got a 03 roush I bought a while back. I changed the sparkplugs, cleaned the throttle body, changed the tranny fluid, installed a steeda tri-ax, and put some nitto's on it. The spark plugs seem to make it run a little better, but still a slight shake every 3 or 4 seconds. I took it to the track and my fastest time was a 15.4, reaction time .013, 60ft 2.29, 1/8 mph 71.26, trapped at 90.29 at the finish line. I launched at maybe 1700 rpm on this run, previous runs were slightly slower and launched at idle, i shifteed at about 4700 1/2, 2/3 at about 5200, 3/4 4900 or so. I had 5 runs and this was the first time ive ever raced a car. My second fastest time i shifted at 5900, rpm or more every shift and let out of it before the 1/4 ended...i got scared lol
