Heres the story, sorry for the length but you'll understand it better.
So I just got done installing my Dynatech LT's and a few other replacement parts and gaskets on my 93 Formula. Well I got everything back together and it all went well. (Open headers http://images.ibsrv.net/ibsrv/res/src:www.ls1tech.com/get/forums/images/smilies/LS1Tech/gr_grin.gif) Now mind you I don't have my o2 sensors hooked up cause i'm waiting for my 4 wire Heated o2's to arrive. So me and my buddy went and took it for a test drive cause i'm impatient. The car ran great but just a little rich on the fuel is all and so I went and did quite a few pulls with it just cause it's impossible not to get on it with open headers and naturally my SES light came on after awhile but didnt affect anything.
After 2 days of just a little driving around I came to a stop light and out of the blue I took off and it started "ticking" sort of like a header leak in a way
(but it's not). Well i drove home and it seemed like it was under powered. Still starts fine, don't smoke, oil pressure is good (60 PSI+) but has that ticking sound that follows the RPM of the motor but it's only the drivers side that does it.
Did a compression check last night and all cylinders are about 120+ PSI and they hold the pressure. Spark plugs are fine except maybe #5 which looked maybe a little bit more wet, not sure. Wires aren't burnt or anything. It almost sounds like it's "detonating" or pinging on just that side of the motor on one cylinder. Took the Valve cover off while it was running and everything looked like it should.
What the hell could be happening? Would the 02 sensors cause the computer to make a lean condition or something? I just don't know what would cause this?
Anybody have an idea??
Thanks
