What is the main cause of my FC bogging?? I've changed the oil and spark plugs.... and when i started it up the first time it ran perfect. The second time i started it and drove it around the block it started bogging... what is the problem?? fuel pump, injectors, or some mechanical problem????

Just a quick response that will help others help you. NA or TII, S4 or S5? any smoke on start up? Is it bogging all the way through the rpms or just a stutter and falling on its face at a certain point?

its a 1990 NA S5, and it does smoke when i start it up, but the second time i start it up it doesnt smoke. My RPM gauge doesnt work so i cant telll u the exact rpm when it starts bogging. From hearing the soound of the car i think its around 3k+. The car would ususally start up fine when i drive it and after maybe a hour of driving it would start bogging and bog for the rest of the day... =[

for your rpm gauge check your fuse to see if you can fix that so we can see what rpm it starts to act on you
