skunkanova

did a full tune up...the wire to the 02 sensor was rusted through....and when i took out the rear leading plug i got it out...but the piece that goes from the wire to the engine came out due to rusting....old plugs apparently...or possibly something worse....but anyway... on with my long *** sentences...i put the plugs and wires back on, and the o2 sensor back on....and now the ****** wont start..itll go up to about 2k and just die.....wont run for any length of time....im using the ngk 7q and 9q plugs....as stated in the manual...7s in the bottom 9s up top.....top plugs to the coil nearest the rear of the car and the bottom plugs to the coil to the front of the car, just like it was when i took it off.....im lost...any help?

Check you air flow meter to be sure it's plugged in. Also check to be sure you didn't know the big hose that comes off the rubber intake boot the upper back part of the intake off messing with o2 sensor...



Basically just check for vacuum leaks...

sounds like a vacuum leak to me. Check all the hoses and things make sure you didnt knock anything off or nothings broke. Sounds like everythings really old on that motor anyway.
