1994 Buick Roadmaster 5.7L LT1
Nicest car I've ever owned, but not the most reliable
Replaced rear shocks, brake line, thermostat, exhaust system from cats back, front pads and rotors, flushed coolant system, emergency brake cable snapped.
New plugs, new ignition coil, 2 new tires (one exploded on me).
Bad wire from battery to fuse box under the hood.
Beginning to hear ticking from valve covers.
Probably my favorite car I have ever owned. It's fast, smooth and comfortable.
It hasn't run well in a couple of months, and I just keep throwing parts and time at it, and I can't find the solution. Maybe it needs a new set of wires or new Optispark. Maybe the cats are clogged or it could be a sensor or vacuum leak somewhere.
My knowledge of cars is pretty limited, and it's very frustrating to me that I can't fix it. I love this car; I just can't get it to run right. If anyone has any suggestions, I could go into detail about what's wrong with the car and maybe you could give me some suggestions. It would be greatly appreciated, as I'd hate to let it go if it's a cheap easy fix.
I've owned an 81 and an 86 Caprice, each with over 200000 miles on them, and neither ever gave me any problems besides extreme amounts of rust and rot, and minor mechanical things. I assumed I'd get the same or better from the Buick, but it hasn't been the case. Damn it, I wish I knew more about cars!
Would you buy another car from this manufacturer? Yes

Sorry to hear about your issues. I have owned 2 Roadmasters, a 1995 and currently a 1996, both sedans, and I am currently hunting for a wagon. Is your car throwing any codes? The Roadmasters have a built in diagnostics center in the climate control that I have gotten codes from, even without the light on. Also these cars have one of the best online communities, between the Buick forums and the Impala SS forums. Let me know if you want my email, and I would be willing to try to help you as best I can.
* '94s are well known for issues with the opti, as water can get into them.

There are a couple of online forums for Roadies and their cousins. A lot of those people are very knowledgeable and helpful. They can point you in the right direction. The ticking may be an exhaust leak, the LT1 engine is famous for them.

The Roadmaster is now 22 years old. Preventive maintenance on any car stops most problems. Just listen to the car. I've owned it for 19 years and am extremely pleased with it.
A couple of tips:
Put about 4-6 oz. of thread cutting oil in the radiator. It's permanent. Never change the fluid again.
On all grounds and weatherproof fittings. Open them, put some wheel bearing (heat resistant) grease on terminals and they never fail. About 80 percent of all electrical failures are microscopic corrosion on the contacts. You can't see it.
Example - last night your TV remote worked, now it doesn't. Bang it and now it works. You moved the batteries and made new contact.
About a front end crash - there's 10' from bumper to your chest!
These tips work on ANY car.
