I've been getting 90/91 Fuel Control codes. I'll occasionally see misfire during warmup on multiple cylinders. Car seems strong (no reference to what strong is or isn't) but has a 'lumpy' quality to the running at all engine speeds, esp. noticeable slightly lugging. I thought a bad cylinder or miss, but all sparks look normal, good compression, and no specific cylinder codes. I have some VANOS noises, but no codes for that. The last VANOS code was an exhaust CPS when I bought the car. Replaced it and no VANOS related codes since, although I do have the other three CPS's ready to be installed when I get a chance.
New sparks/MAFs/precat o2/fuel filter/air filters.
