What is wrong with my Buick?

I have a 94 Regal 3.8. I just changed the spark plugs and pcv valve. Before that I took it for an oil change. After the oil change the car began making a grinding sound when the wheel was turned all the way. After the spark plug/wire change, the car is now shaking slightly when in gear. It is worse in reverse and non existant in neutral. Also there is a clicking sound coming from the engine (not sure if it is new, or I just never noticed). The car has 164,000 miles on it. What do you think is wrong and how much should I expect to pay to have it fixed? (Or even better how hard would it be to fix myself?)



All fluids have been checked and are at an ok level. A mechanic said recently that there was some metal shavings in the transmission fluid.What is wrong with my Buick?One thing at a time. Oil change and wheels are not related....so the noise was there before the o.c.. Would guess that the rim of the wheel is rubbing on the frame. There is a steering stop that can be adjusted to prevent the wheel from going over that far.

After spark plugs and wires were changed

car runs rough.....you crossed a wire someplace or you have a dead new plug.

Clicking noise could also be a spark jump from a spark plug wire to ground(either on the block or the frame) look under the hood at night and see if you can %26quot;see%26quot; blue sparks%26gt; fix that and it might just run better too....for that would give you the dead cylinder.

Metal shavings in tranny fluid, normal.What is wrong with my Buick?Dude your grinding noise issue has nothing to do with the oil or spark plugs. You better go have your tires/ball joints/suspension checked. I know this sounds weird comming from a girl, but my husband has his own repair shop and I've learned a lot. Sometime tires shake because of the tire having a broken belt inside.



As for the clicking sound you would have to be more specific. Maybe you have wires crossed.What is wrong with my Buick?I think you should start to look for another car. The buick you have is on it's last leg. I am a mechanic at a local car dealership and i have years of experience repairing auto's... your problems don't sound good...What is wrong with my Buick?The shaking that you are describing is your engine misfiring. The reason it is OK in neutral or Park is that your engine is not %26quot;loaded%26quot; in these positions. Only when you place a load on the vehicle- drive or reverse- will this condition manifest itself. I bet if you were to drive this car at about 40-45mph in 4th gear with the torque converter engaged and slowly accelerated the car you would feel this shaking on a larger scale. The rear spark plugs on this engine stink to get to and can easily be cracked if you aren't careful. I am pretty sure that your problem is ignition related. Do not forget to check the ignition coils for carbon tracking-black soot-if you see this replace the coil(s) as well.



Good LuckWhat is wrong with my Buick?lean toward it being a cv shaft (axle halfshaft) if its a fwd, otherwise get under it an see if they left something wedged up under your cars driveline components. a cv shaft u can do at home if u are mechanically inclined but they can be a pain an can also get pricey, they typically pop when turning. if they go out when u are driving u will know bc the car will no longer accelerate and just roll to a stop. u can always drain your tranny an investigate, usually shavings accumulate on the magnet thats in the tranny pan if there are any at all. investigate for yourself unless u know the mechanic VERY well to be safe. good luckWhat is wrong with my Buick?STOP steering it all the way over on either side!



there is NO need to turn the steering wheel all the way over until it hits lock left or right. By just backing off a tad until it is OFF lock, it will keep the pump from straining pressure thru its relief valve, and causing a lot of wear on your pump AND also you will not lose any of the front wheel steering angle you are trying to get to get out of that tight spot!



When you back off the steering wheel off full lock you are not losing any of the front wheel angle, and also you will not be slamming the pressure into the relief valve!



They probably put the wrong heat range or gapped the plugs incorrectly, they also could have damaged a wire. It is more important to change the wires as they wear out about 30,000 miles (before they start changing resistance) Plugs should last a lot longer than that as cars do not use lead anymore these days which fouled plugs really quickly back then!



They may be using a lighter oil than was in it the last time , that could be causing the clicking sound.



If the trans is shifting fine, then don`t worry about it.
