Leaded race fuel highly knock resistent. So if you still get 43 counts of knock then it's not looking good.
So did it do this before the timing belt job? Or is this a new project all together?

hmm i always thought it would leave alot of deposit in the engine, i put a lot of octane booster in it and it still did it, but i took a friend for a ride and i noticed that the clutch kinda chattered a little bit,could that possible cause i knock that could be picked up? Also i have noticed when it rains the car runs like a champ, and since its been getting colder it is also getting back to running well too. I just think the car likes to mess with me.... lol

I have heard of bad TOB causing knock counts. I've never experienced it for my self.

Personally, I think the knock is a symptom of the miss and not the cause.

The first step is to isolate it to a specific cylinder if possible.

If you can, catch it in the act and pull one injector at a time to see which one doesn't change how the engine runs. Or if you get lucky pulling the plugs and looking at them right after it happens might tell you something.

We have pulled the plugs one at a time and they all made the car act the same. Its not a bad miss... just a "pop" every now and then. If you slowly give it gas in neutral, the higher rpms you go, the more it misses.

It sounds like a timing issue to me.

Where would I be able to get the lead gas from? I really wanna know if it is a real knock or a phantom knock. I also really think it is a fuel problem, but we already changed everything besides the injectors, but we have tested them.

Balance shafts out of phase perhaps?

If you think its a fuel issue, have you hooked up a fuel pressure gauge or looked at fuel trims?
