in my 320i mod. 1993
 

My car accelerates from zero to 80 speed slow it takes me long time to go to 100 >>..

my car is 1993 BMW 320i

the car in good condition

Its good car that manufactured on 1993 and released on 2004, so might be in good condition.
You have to see auto parts for external manufacturing.

What is the car doing? Any particular noises, warning lights? Does it bog down when you go wide open throttle? Did it start doing it recently or has it done it since you bought it? When was the last time it had a service (oil change, fuel filter, spark plugs)?

No noise at all
when I push on the Accelerator over normal it gives me what I want
and its like that since I got it
I have to change oil in those dayes, I have never changed fuel filter, and never changed spark plugs.

>> What I have to do to make light Maintenance with out paying to much

Well, new fuel filter and plugs would be a good place to start. Resetting the lights have a couple of alternatives. look around they're on the site here
