i have a 93 lx coupe 5.0 with heads,cam,intake. the problem is when i turn the car on it will run fine fr a few minutes but then when i drive it, it will buck when you cruise at a steady pace but when it's under a load it will run fine. Also, when i race the car or put it under a full load it runs AMAZING. the car is running rich and sometimes will load up so much that it will start to misfire. i have 24lb injectors and a pro m mass air.i have changed the computer, map sensor, mass air, injectors.....i dont know what else to do and am so frustrated with this car right now!! can anyone help on this subject??????

you dont think it would have anything to do with the ignition harness or wiring?
