My accord has been running like crap for about a week. there is a chance that my timing is off but before i dig into that area wanted to run a compression test. i have the f22b1 vtec engine. my 4 cylinders read #1=165, #2=165, #3=150, #4=150. Two parts here. is this in the range for the engine? is a 15psi drop acceptable? if you know any other areas i should be paying attention to please throw that in as well.
