ok guys sorry for the length, but I want to make sure to get an accurate diagnosis. I have researched and asked and have found no prior case such as this. My 96 Gsx started out having a very bad idle and a small arcing like sound coming from the general area of the 3rd cyl. It is not the plug, and I cannot pinpoint it. I have changed the plugs and wires. It has a very bad Idle. It is an AT car. and when I have the ac on it will idle at about 1100 rpm in park and neutral. When I put it in gear, no matter how high the biss is, it idles down to about 200 rpm, sometimes to the point of choking down. It is very hard to crank cold, and you must let it warm up before driving or it will die. It has progressively gotten worse. Now, when at a stoplight, when I go to accelarate, it hesitates sometimes going nowhere almost 5 seconds, regardless of how hard or light I mash the gas. Now it has started bucking during driving at about 3500 rpms. I have to let off the gas to make the gears change, and I can only go about 65mph without violent bucking. Today to make matters worse, It has started backfiring in conjunction to the bucking. I did a compression test, and it read 155, 175, 175, 155. The number 3 plug though only a month old, is black and fouled signifigantly worse than the other 3. I am at a loss. Might it be the ignition module? The guy at the mitsubishi place said it may be a timing belt, but I do not believe he was right, seeing as how he did not even drive the car, and it has 100k miles on it. This particular dealer is notorious for performing unneeded maintenance to vehicles at high labor costs. Any suggestions or ideas, guys, I would appreciate it greatly. Thanks, Josh
P.S. I checked the oil, it is up to level, but I only have 1600 miles on it and it is black as crap, more than it should be for this many miles. I use mobil1 10w30???????/
