i had the pfc and commander hooked up to my 1994 FD for the last six months, and it ran well with only one problem...anytime the water temp went above 88 degrees celsius, my car would bounce the rpms from 1100-2200 until the water temp cooled back down to 87 degrees celsius. and a friend on the forum advised me that if i followed the install instructions from dave, my car would no longer bounce the rpms above 88 degrees celsius. so i followed the instructions, did the idle learning process, then went for a drive....the car ran perfect. that was yesterday. today, i started my car and allowed it to warm up to 80 degrees celsius before i began driving. and i start driving, and as soon as i push in the clutch to stop, the car stalls out...i restart it....drive.....stalls when i stop....it did this 3 more times.....then after it ran fine. later today i leave work and it does the same thing. can anybody offer an explanation? i have the follwing mods.....99 spec turbos, down pipe, mid pipe, cat back, y pipe, pfc, mild streetport, apexi CAI
