Default 1995 buick regal minimal problems

hi all, I just bought a 1995 buick regal custom with the 3800 engine. I need some help please. 1. I noticed my rear side marker lights were not working. 4 door. I got under the car and there was no wiring harness to them at all. I looked at the wires going to the brake lights. there does not seem to be any wires cut from there at all.
2. my car has 2 fans on the radiator. only one kicks on no matter what I do. even with air condition on still only 1 fan runs ?
3. I notice a very slight miss at idle. you can also hear it putt putt out of the exhaust. its not using antifreeze and it runs excellent as soon as you give it gas. I mean the car runs excellent just the very slight miss at idle. I hope its not the dreaded intake gasket . I don't think it is but I don't know everything about cars but I know more than your average joe.

please help me if you can, ty

Funny. I have the same car. Mine was in for inspection and they told me that the rear side markers were out and had to be replaced. I told them to go ahead and replace the bulbs. he came came back about ten minutes later with a confused look on his face and said there was no wiring for the lights. I have always thought that it must have been in an accident and the body shop did not replace the wires. Guess im not the only one.
Regards
Rick

Great topic. The taillight/marker wiring I've worked on was all interior, not under car harnesses. Routed through trunk and hollow interior cavities. No wiring at all, don't know lol. Possibly an option for rear markers back then, just had prism/reflectors in place to fill opening? Not required if factory omission, same with no seat belts if car is old enough, not OEM before '68.

Radiator fan may be bad of coarse but could be on separate thermostat for overly high temp? Does motor overheat or run hot? Fans used to freewheel (belt driven) and had a viscous fluid heat activated to latch in operation.

Skipping motor at idle, in '95 cars still had distributors (optical points), HV coil, rotor, wiring and plugs of coarse as far as I know? I'd try replacing all, sounds like bad wire, fouled plug or connection (typical tuneup). Or possibly a sticking/collapsed hydraulic lifter, an additive as Marvel Mystery Oil would free that up and recharge with oil. Used to on occasion fill crankcase with kerosene and run motor for a short time to clean sludge out in the '60's. Some comments on this: Kerosene to flush engine??? | NastyZ28.com. I don't know if it was a good idea or not lmao.
