I have a 1988 Oldsmobile Ciera 3.3 V6 with 90,000 that I have had for 3months, about 2weeks ago on the way home it loss power, and it sound like the engine was louder or a hole in the muffler, then by the time I got close to home it stalled then i couldnt start it, I let it sit for hour and it started i got about 2 miles and it stalled again...so i left it and come back the next day it took like 3mins to get it to start but i got it home....now if i try to start it its very hard some times to start and i have to give it gas to keep it running or it will stall. i cant get it going for 30mins-hours but it will start again" it has A knocking/clicking sound at the back of the engine, it still has a power loss and it gets kinda HOT. Ive drove it 30feet in 2weeks what do i need? PLEASE HELP!!! it also sounds like a gun shot some times when i try to start it, and it sounds like a bubbley noise from the engine I think.

Best thing to do when it won't start is to find out what you are missing. Fuel or spark? That will help narrow things down...
On this car after hearing what you said I think I might take a quick look at the exhaust system.... Also most sounds like a restricted exhaust problem.... After it's warm hook up a vacuum gauge & see what the reading is @ idle & then high rpms.... If the reading is low @ idle & goes to almost zero at high rpms you may have a restricted exhaust system. Being able to take a back pressure reading would confirm it. If not you can run it until it dies & then pop out an O2 or take the pipe loose from the exhaust manifold to see if it will start back up (yea I know everything is hot but no way around that )........

Thanks for your help so far" well this week I found one problem to be the air filter, it was really really bad plus weeds and a dead mouse in it...i know thats pretty bad! well after changing it the car starts up alittle better... i was even about to take it to the store, but if it warms up it will not start for hr the fan does work though. now when I drive the car it feels like its not getting fuel or something doesn't have any pull, it does not go real fast, it takes time to get it up to 15mph to 25mph it fells like to wants to stall and if i push on the gas to far it will stall out but will start up aslong as its not warm. All the spark plugs are sparking, and i think the catalytic converter may be clogged, the bolts are rusted and i cant get them off, so i will be putting a few drill holes in it to find out if that is one of the problems!...I took off the start of the pipe right after the exhaust manifold not sure of its name, the pipe that connects the the front 3 to the back 3 and goes to the catalytic, there are 6 pipes that come from the engine the front 3 and the back 3. the back 3 that still was connected kinda to the catalytic converter had the open end though that had black smoke coming out of the pipe, The front 3 showed no smoke from its end that was opened" this means what??? I'll try the vacuum gauge also

carproblem; The 'black smoke' is indicative of overfueling, which will destroy a catalytic converter. The saying is "Catalytic Converters don't die, they are murdered". Try removing an oxygen sensor before you start drilling holes. It will be noisy, but if your power comes back, you can be pretty sure it's a plugged cat. The vacuum test is another good indicator. The vacuum at 2500 rpm should be as great or greater than the reading at idle. But.....you need to address what caused the cat to go bad, in the first place, or you'll murder the new one...if that's the problem.
