Strange problem came up a few weeks ago and I have yet to figure out what is causing it... let me explain.

Sometimes my car will bog down and wont let me get above 1750 rpms. I can turn the car off, turn it back on and it will work fine for a few minutes and then do it again. I've replaced the fuel filter and no change, I've also checked the running pressure of my fuel pump and it stays inside the operating psi and doesn't change when the car bogs down.

I am sure this is someting electrical, but I havn't a good idea of what i am looking for, can anyone help? Someone told me that it is possible that my coils are deteriorating, could that be what is happening?

ANY help would be greatly appreciated. Thanks!
