oh another thing. i dunno were the hell it went to or what it supost to connect to but the driver side 02 sensor isnt pluged in to anything cause i dunno what happened to the plug that plugged in to it lol and it sounds like my headers leaking on the driver side i dunno whatelse to do to it its as tight as i can get them... if anyone has any suggestions or ideals id really appreactie it guys!

 

[89RedFoxGT]

I been looking and looking for the other plug that plugs into the driver side o2 and i cant seem to find it? the one from the passeranger side plugs in under the MAF and goes down to it but i dunno about the other one?? can anyone tell me were its supost to be? I'm pretty sure its got something to do with it runnin like chit, and anyone that has any ideals at all please let me know!!! again thank yall and sorry for all the questions I've had the car almost a year and never drove it and i got ab out 3,500 in the car alreay so im pretty much ready to drive it....

Header bolts will keep coming loose for awhile, so yeah, you will have to continually monitor them and tighten them. The o2 sensor plug is attached to a whole wireharness. You will probably have to look around under the car for it, its possible it may have wrapped around the engine mount or something during install. Its there somewhere. As far as your timing which is probably waaayyy off. If you moved that distrubutor when the car was off after tdc was set, you will have to go and find tdc again. If you want to try and find a sweet spot with out a timing light. Start the car, remove the spout connector, loosen bolt on distributor a little and turn distributor clockwise. I highly suggest you go and buy a cheap 30 dollar timing light at your local auto parts store. Trust me, that thing will be your best friend.

yeah tomorrow im gonna put it up on stands and put the driveshaft back in it and find the other 02 plug.whats the easiest way to know if the pistions at tdc? and my friend has a timing light im gonna get I just figured I could get it close enough so it dont miss like crazy when you revv it? its got new plugs and wires what would make it miss like that? im gonna set the timin tomorrow and go from there... any ideals would be nice yall and thanks!!

Pull #1 spark plug, stick your finger in the hole and rotate the engine until you feel compression, wait for the piston to come all the way to the top, and you have TDC.

do as mentioned above. When he says compression stroke, he means you WILL feel air coming out of the spark plug hole. That is the best method. I ususually do this while i lay underneath the front of the car. I put a socket and wrench ont the crank bolt and turn the engine over with it while i have my finger over the spark plug hole. When you feel air blowin your finger off the hole, now is the time to look for the zero degree mark on your dampener. Line that zero up on the timing pointer EXACTLY and your done underneath the car. Next pull your distributor up and position your rotor at 11oclock (some do 12 but 11 gives you more room so your wire harness doesnt hit your water neck if trying to advance timing past 16 degrees). Then put your cap back on with your number 1 plug terminal close as to the middle of the motor striker as you can. Tighten down the distributor SNUG enough so it DOES NOT move when you are starting the car. If it moves, you will have to start all over again. Once the car is started you can adjust the distributor to advance your timing. AGain, tighten down the bolt before you shut off car. Also check timing again after you tightend the bolt. I forgot to mention that you must remove the spout connector after you start the car to advance your timing
