your float could be stuck
Not overly familiar with the Lumina, but you might have accidentaly disconected them at the bus, or the CD player could be drawing to much power(unlikely)
I had a similar problem turns out the Alternator was bad.
Yes any camshaft can break if something goes wrong.
1993 Chevy lumina: check all vacume lines for leaks and or splits around intake.AnswerIf you are not actually moving (just revving up the engine), it is normal for the engine stop at 4000 rpm. (governored)
Probably because it has a big tank that fluctuates. I could be wrong too though.
The 2001 Lumina has the OBDII system. The only way to access the data is with an OBD2 reader (about $120 ) from any FLAPS (Friendly Local Auto Parts Store) Or you could take the car to a dealer and pay them to read the codes. Purchase the Haynes manual for the Lumina so you can look up the codes and figure out whats wrong.
Ignition module. See if spark plug wires have arched. Check for spark. You could change it yourself. Module plus new wires will cost you around $200.
Could be temperature sensor Could be gauge
Could be a number of reasons. I'd recommend you take it in to a shop and have a system performance test done on it. While you could do it on your own with a manifold gauge set, you would have to be able to decipher what the pressure gauge readings indicate is wrong with the system.
Could be low on coolant or a faulty thermostat.
There is nothing wrong with the reverse lights. It is probably your turn signal switch. They are bad in the 1995 lumina. If you do it yourself it should cost about 100 bucks. Good Luck!!
Yes if one or more gauge is reading wrong
