I have been building up my gsx and recently installed a 14b w/7cm, 660cc's, and tuned with ECUFlash. Car was running GREAT for like 6 weeks.
Recently I have been getting misfires in cyl #1. I changed plugs and no help. I changed wires to different cylinders and still just on cyl #1. I did a compression test and got the following numbers from cyl 1 to 4: 140, 150, 160, 160.
The weather has been REALLY hot around here lately and I wondered if that can contribute to burning a valve? I don't have a fmic and was getting a few counts of knock, but nothing over 7. Could that be an issue?
I have some hks 264's in my garage waiting to go on, but I figured that with that 140 in there that I might buy a new head and get some nice springs and such and install the 264's. Then later, after its built, toss it on. What do you guys think? Do you think I should do something else? Maybe 272's?
