So, which one do you think I should replace first? The 7x. the 24x, or the crankshaft? Or should I just do all three and be done with it? Which one might be affected by heat/cool thingy like the original question?

Just so you know Buickfosure the ignition control module and the coil packs were both replaced but did the same thing. But you said crankshaft and/or camshaft sensors. And does the 96 3100 v6 have two crankshaft sensors I have seen 7x and 24x sensors advertised, what the hell does that mean?

I have cleared it out multiple times... keeps showing up... why would it tell me random/multiple cylinder misfire... duh OBD-II it's obvious it is misfiring WHY? Sometimes when it was acting up like this I could turn the key to the on position then off then on then off but not to the starting position and when I did turn it to the starting position it would make a more valiant attempt at starting or actually start.

the only code that ever shows up is Random/multiple cylinder misfire.

Is it possible the Throttle Position Sensor is shot, because the car is not starting at ALL right now. And when the car was running it would only act like this after you warmed it up, shut it off and let the car sit for 20-90 minutes or so, but yet would run for 650+ miles in one day as long as you didn't let it sit for more than 20 minutes. I have been told multiple things such as Camshaft Sensor, Crankshaft Sensor(and apparently mine has two{7x and 24x}, MAP, MAF, Air Charge) I mean if it is one lousy sensor fine, but if you add the price of all the stupid sensors I might as well replace the engine.

Actually I have to ride the brakes because if I let the engine rpm go down it starts flooding itself again. And do you mean MAP of MAF sensor and how do you test them or can you? Oh and I forgot to add that the missing/sputtering/flooding, whatever the hell it is has also happened when I got stuck in rush hour traffic in Milwaukee, but not as bad.

Stupid question but with the metal to metal sound is your a/c or windshield defroster on or off?

I have a 96 Lumina with 181,000 miles on it. Since last summer when I left the car idling for 30 minutes plus I have had this annoying problem where after you run it til it is warmed up and shut it off for 20 minutes to an hour and a half or so it will run horrible.. very rough like it is either flooding or choking itself. If I am fortunate enough to keep it running(while riding the brake and gas pedal at the same time) after a couple of miles it runs fine. If I am not fortunate it will take almost the entire charge of the battery to start if I am lucky. Recently I filled it up with gas at the local gas station just to have it do the same thing but was not able to keep it running and has not started since(2 weeks ago). I have replaced the coolant temp sensor, the PCV valve, the Ignition Control Module, plugs, plug wires, coil packs, fuel filter. HELP!!! Someone else has to have had this or a similar problem. By the way, there is plenty of fuel getting to the engine(you can smell it). HELP!!!!
