I read through the search (compression tests) on here and finally decided to do the compression test myself. I just have a couple of question.
1. What happens if the psi between each plug is more than 14?
2. Another thing, what does "crank/turn the engine over until guage stops responding" mean? (I know this is a stupid ?)
3. Should I give full throttle or not, whats the difference?
4. Can you check it by turning on the car for a short while, letting the guage measure the pressure, then shutting off? (my friends mechanic told me this was okay to do, but not sure)
thanks in advance
