I have a 1986 Honda Accord LXi HatchBack, its Fuel Injected, 4 Cylinder, its a Manual. Ive Changed the Fuel Pump, Fuel Lines, New Spark Plugs, Cables, Air Filter, 2 New Fuel Filters, and a new Pressure Regulator,cleaned the fuel injectors, and it still gives me a problem. When I drive for about the first 5-10 min, it drives fine, but after that I cant press my acclerator that much other wise my car will shake a little, and I loose alot of speed, and my car wont go, but if im on the highway and i barely press the accelerator, it will go fine, its just the fact that when im at a stop light, i go real slow because i cant press my accelerator that much in or it will start shaking and sometimes my car will shut off, and sometimes when i do press the accerator all the way down, and then i take my foot off, ill push my clutch in, and look at my RPM Gauge, and it will go all the way down to like 0 and if i press the accelerator it wont respond, it takes about 8-10 Sec until my car starts to respond again, I have no idea what else it could be, when i did change the fuel filter, the gas that came out of the fuel filter looked like mud, ive changed the gas and put in new gas, with it, and used some fuel injector, gas, cleaner product. it ran a little better but still acts up, do you have any ideas what this problem could be, and what part i would need, its nothing really in the engine, its a fuel problem, Bad Gas or Something? Please leave me some help. Thanks.
