my zc is really bogging at rpms lower than 1500, after that it picks up steadily, and it gets worse once the car is warmed up? i have a zc with a dc sports header, new cat, 2" 1/4 exhaust, intake, new spark plugs, plug wires, cap and rotor, timing belt (and yes the timing is set right, first thing i checked) brakes arent binding, ???? what could it be and what should i check, i did throw a mapp sensor code a few days ago and just reset the ecu and it went away (if this would be of concern) and also a eavc code (i think i was resetting the idle and it threw that one but not entirely sure if it was a seperate occurance) any help greatly appreciated, because it will really bog when i try to start rolling at a light and then once it gets going about 20 feet and it gets into the 2k rpms it starts taking off? any one have anything like this b4?
