I have a 2001 Ford Focus with a manual transmission and the code I got at O’Riely’s #1 cyclinder missing. I have already replaced the plugs and wires. more about the car on post June 29 2010
How about a compression test?
I enter the code incorrectly PO301
I get 30 highway and around 23 city mpg
sticky valve?
What would a compression test show?
