[QUOTE="mebcop, post: 14279508, member: 70119"] OK, something interesting. I was watching my fuel trims last night and they were crazy. When my car was tuned it held within 0-3% fuel trims (LTFT's stayed at 1.0) 99% of the time. Last night as I was driving down the road with cruise control on 60mph, and it would read between -16 and -19% for a mile or so and then it would swing to +15 to +19 for a while. Every so often it would come back to (-2) - (+2). Its like someone flips a switch and it flops from -16% to +16%. It'll stay on -16 to -19 for a mile or so(sometimes 4 or 5 miles even), then +16 to 19 for a while (sometimes a mile and sometimes like 5 miles). I thought maybe it had to do with the evap valve opening with a leaking tube, so I shut the car off, unplugged the electrical harness so it would default closed and then started the car back up and drove it. That didn't change anything. I am still buying the roush intake but I'm worried it won't fix my problem. [/QUOTE]
