Its called a period. If you use them you don't sound like a raging lunatic.

Anyhow, how about you just test your ignition coils, huh?

If you don't know how to do a compression test, how did you manage to swap out the block? I hope you torqued everything down to spec...

For a compression test, you can buy the thing or rent one. I don't know how much it is to buy, but it's a little gauge with a rubber hose with a fitting on it so you take out one spark plug and screw the gauge in then crank your engine for about 3-5 cranks and see what psi your reading on the gauge, that will be your compression for that cylinder. Repeat for each cylinder.

Renting one I believe you can do at an autozone or kragen, it's like $70 but then when you return it you get your money back.

Search. First you need a compression check tool you can find at a local auto parts store. It comes with instructions.
