Unless you have a/c equipment, you're going to need to pay a mechanic of some sort to fix the a/c issues. My '94 had a leak around the thermostatic expansion valve I think it was and I replaced it myself, replaced the accumulator, and recharged the system at my school. Usually, these things leak from the evaporators though and that job involves taking the dash out/apart.

The engine misfire can be fixed by you if you find out why it was missing. If it just needs plugs and wires, than it shouldn't be too bad so long as you can get underneath the car to remove a few of the plugs and wires. If there is some other problem that is causing the misfire, than youll need more info. before we can tell you how to fix it.

The alternator is easy. If it does in fact need to be replaced, just get a new one, remove the belt, and like 2 maybe 3 bolts later, you're done. I would get a manual for this car if you plan on doing more of the work yourself. It will give you step by step directions on how to fix everything from oil changes to rebuilding the engine.

hi man.,.

thank you for reply.. l have the manual and it helps..

l am gonna explain when this misfire happened.

l was at the light and a cadilla pulled next to me and he said that my car was slow and he wanted to run and we took off, l reached to between 110-115 mph and l felt or heard a little thing from the engine and and right after that l saw service engine soon light came and l stopped accelerating and l drove home then to my mehanic and he read the code and it was multiple misfire..

now do u guys get an indea what my problem is and how to fix?

sometimes my service engine light comes on, sometimes it flashes and sometimes it is going away like nothing is wrong.. right now it is not on.. but l know tomorrow or other day it will come bacck again.



still need advices..

thank you..

that multiple misfiring thing is something that could be potentially difficult to diagnose over the net. Sorry, not trying to be negative, but it could be a some what faulty opti spark deal, or plugs that need replaced, actually any number of things. I'm hoping Mr. Luos will see this one, he probably will know right away. Sorry I couldn't be more help but more luck.

no man.. thanks for helping..

how am l gonna diagnose that then? if it is not the wires so whatelse could it be? will l have to pull the engine down to fix it? should l just go ahead and replace the wires?

my mechanic said that my car will need to replace all the wires.. actually needs a tune up. should go ahead and change the wires and see what happenns? or take the wires off and see if they are ok?

about power, l am 90% sure the power still there and the care is still fast.

[doodad]

actually guys..

where should l check to fix this problem or dignose this problem?

[doodad]

l just talked to my mechanic on the phone..

he told me that my car needs a basic tune up and which means 500 bucs parts and 300 bucks labor. total 800 bucks.

he said, we need to replace the spark plugs, sprak plug wires, caps and rotors. and he said, generally caps and rotors couse the misfire problem.

do you guys think that l can replace those parts by myself?

[CreepingDeath94]

$800 sounds about right. The job is a pain and takes forever if you dont do them everyday. If you have the original plugs and wores on that 130K mile car, then that is probably your problem right there. I would go ahead and replace the plugs and wires. That car doesnt have a cap and rotor per se, it has a cap with an optispark sensor under the water pump running off the cam. You could do it yourself, but it will be very difficult if you cant put the car in the air with a vehicle lift. Either way, the tune-up sounds like a good place to start because if they havet been done before, you need to do it anyway then.

well, l have those little things which you drive the car over them so the car gets higher and u get under it. would that work? so do u think, l should replace the cap/rotor kit, wires and spark plugs? l asked my mechanic and he told me that l cant do that by myself, it is hard and l could fuck up with stuffs he said. and now l am scared..

is there any step by sptep insturctions with pics how to remove and install wires, sparg plugs and cap/rotor kit?

thank you so much for help...

The easiest way I have found to change plugs is to have someone else do it. Aside from that, make sure the motor is cold when you change them as you are going to bump the exhaust manifolds with your wrists and arms. The last lt1 plugs I changed, I did the front and rear plugs from above and the 2 middle plugs on each bank from under the car because I couldn't get my arm between the valve cover and the strut tower. If you put your car on ramps make sure its secure and won't roll off or fall off as there isn't much room for you under it if it does fall. I used a 3 ton floor jack and jack stands, lifted the car about 12 inches and was able to do it, but the car was cold (had sat overnight) and it wasn't too bad, just dark and dirty under there. As for wires, they can all be done from above, same thing though make sure the engine is cold.
