4v coils in a 2v?

I need to test my coils and the only ones I can get ahold of are 4v to put on my car to see if mine are bad. I don't know what the difference is besides the fact that they go straight down and not at an angle. Will they work with 2v boots?

4v coils will not work on a 2 valve. There are no provisions for bolting down the coil on a 2v. Also the polarities are different.

K. I wasn't sure. It was just to test the stock coils. If the other coils run the engine better then my coils are bad. I know it can be a bunch of things wrong besides that but that's the easiest problem to fix. I've got good fuel pressure and new plugs and o2 sensors so the next step is the coils. The engine just feels like it lost a chunk of power out of no where so that's my focus.

We have returnless fuel systems. With that said the fuel pressure is computer controlled. You need to first replace the filter then start diag. I have had the same issue myself. Where it seemed like under WOT the engine seemed to be under powered. I had a bad injector and the fuel filters time was over. If you replace the filter make sure you get a Stainless one.

Well it's not really just at wot it's all the time really. But the fuel filter would be a easy and cheap. So I'll do that tomorrow

I changed the filter. It made a big difference. Especially since the idiot before me had put it on backwards. I still haven't drove enough to see if it's still doing it or not though.

So far it seems to be running better. It's untuned and cammed and it doesn't bounce around at idle anymore.
