i was driving my car the other day, doing some mountain course, and all of the sudden i heard a very small pop,,, it sounded like a small back-fire,,, anyway, immediately after my car started bogging down, and it was very difficult to drive, it would barely make it over 2000rpm,,, i was able to drive it home and the next day i changed out the ecu, and that did nothing,, so i checked the spark plugs and they were black, so i cleaned them with some high pressure air, and then started my car and it idled fine for about 2 minutes and it started bogging down again,, does any one know what might be the problem? the spark plugs maybe? once they were cleaned off the car idled fine for a bit, so I'm confused,, maybe the injectors?? the car spits out black exhaust indicating a very very rich a/f.. please let me know what you guys think
thanks
