88 rex w/ b16a. alllright.. so here goes. in the morning when im letting it warm up, it will bog out, then go back to idle, then bog out again continually until it warms up. once it warms up its fine at an idle, but when im driving at a steady speed (foot at a steady spot on the accelerator.. not accelerating or decelerating) it will start to feel like im letting off, then hitting the gas, letting off then hitting the gas... but my foot really is steady! but if i go to accelerate i have no problems. Spark plugs, wires, distributor cap, rotor, fuel pump, fuel filter are all new. Throttle body is clean, ran a fuel injector service the other day, helped a bit.. then problem came back. I'm beginning to think it could be the catalytic converter building up too much backpressure? i dont know where else to look
