I have a 90 LX, and the problem i'm having is at lower rpm's when i'm cruising the car spudders and surges. When i'm getting on it i have no problems, it pulls fine. It's just when i'm cruising it feels like i'm going over never ending train tracks. It is a 5.0 5 speed with 351 heads. It has frp pistons, an "F" cam and headers with full exhaust. Stock rear gears, 3.08's maybe. As far as i can tell the maf and injectors are all stock. I was thinking maybe it needs a bigger throttle body, maf and injectors, maybe it's not getting enough fuel and is choking. I don't know. It's got a fresh tune up with plugs wires cap rotor and coil. Any help or suggestions would be great. Thanks

try cleaning your maf. Could be detonation? plugs look ok when you did the tune up?

if it was a fuel problem with pump or injectors or a maf or throttlebody choking it of air it would not pull like normal well you got on it, it would get even worse. it could be the lose of vacume due to the cam that is causing it just a suggestion.
