like the title says i have some funny noises coming from the back of my car. its like a whining noise whenever i am below 2k rpm. I just changed my plugs, wires, cap, rotor. the car dies on me sometimes, but it will start bak up when i give it some gas. Also i keep getting diz code on my car for the O2, i just changed both of them like 5 months ago. I also got a code for misfire. I am thinkin it has sumthing to do with my fuel system. but i need ya help!

Possible vaccume leak. That would cause a whining noise. I wouldn't rule out a bad map sensor. If your running an o2 code your cars either running very rich or very lean, or something electircal. What do your plugs look like? That would tell you a lot.

how or what causes it to run very rich or very lean and what does it do? also ive heard the the whinnning noise miht me a bad fuel pump. Im thinking bout upgading my whole fuel system. Fuel pump, fuel filter, injectors, and possibly fuel rail. I got just I/e/h. what kinda prices am i lo0king at for these and which should i use

are you sure you put the wires back on in the right order? are you sure you put the distributor on the right way? are you sure it's not a bad wire instead of the sensor itself?
