go to the nearest parts store and ask for a helicoil for spark plugs

on alot of vehicles from the mid 80's and newer you have to take off your steering wheel and get a tool called a lock plate remover... take off your horn assembly.. your lock plate(locks your steering wheel from moving.. ) and then you need the key... try to turn it to the accesory position.. towards you.. it should slide out and new lock switch slides in... these are generic steps.. your car may be a little different.. but it should give you a good enough guide to either try or maybe get a friend to help good luck..

maybe a little corrosion on the connection from your alt? it could cause the higher resistance to make the voltage drop. the higher rpm's increase flow of electricity forcing it through the corrosion... maybe???

is this a rare v6 or turbo 4 cyl (dist in back of head and can be moved)/ does your dist have a small black connector in the very bottom (look hard)

yes,

you have to remove all belts before going to timing belts,

if you have to do some experiments than you have to remove all those,

THNX

if no spark do a compression test

If there is condensation building up under the distributor cap, perhaps the cap is not vented properly.

Hi William to start with, check if there is output voltage from the alternator it self ( at the back of the alternator ) using a voltmetre Chould give 14.0 Volt, if is OK, that means you have a broken wire between the alternator and the battery, this is common. good luck

check the wiring connection under the inlet manifold for your cold start injector and your cold start sensor. clean or dry it if dirty or wet. pull apart and clean.and clean the butterfly at your throttle with throttle cleaner.and clean your idle control valve piston may be sticking due to dirt.

need a small 7 mm spanner to remove .mark each lead with a number in the order of removal .change both it and your rotor arm at the same time.

EFI-212 indicates the o2 sensor wiring is open, or the o2 sensor itself is faulty (replace o2 sensor). Rarely, it could be a problem with the LH computer itself though that has its own code: EFI-112.

simple pour coka a cola on the plugs then sand wipe with sand paper let dry then try

You probably have either a bad tach or a bad wire connection. The wiring of the tach is very simple - there are really only three leads to deal with:1. 12v positive from ignition - may be a red wire, goes to switched side of ignition switch to provide 12v when the key is on.2. Ground - goes to ground - usually black wire3. Tach sense - goes to the ignition - usually grey wire4. Light - there is probably another pole for an internal light - this would go to the nav/dash light circuit to pick up 12v when the lights are on. It would have no effect on the operation of the tach.Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using Fixya, and have a nice day.

some cars dont go by timing marks to set distributer you will have to make sure of the way your car gets set the best way is too pull number one spark plug put finger on hole have some turn engine with wrench until you fell compresion then get the piston all the way to the top then check were its at then if its still 180 out then pull it and put in right place only if you feel you can go into it that far
