loss of acceleration+ low idle

[bunge1]

I'm driving a 95 pontiac bonneville se with 143,000 miles i noticed that i have been recieiving a low idle and my acceleration is lower then what it used to be. I just got done putting platnium spark plugs, air filter, and just changed oil. Can someone please tell me where to start, and what the problem can be.

I'd start simple and check your plug wires for good connections and possibly a crossed wire. Was it running fine before the plugs/wires change? Are you sure that you bought the right plugs? I'm assuming that you don't have a check enging / service engine light on. Next step mught be the TPS but, I think you would get a light. These are my guesses. LEt's see what the experts have to say.

i checked the wires,they are fine. i bought platnium spark plugs, they worked well when i put them in, can they be dieing this fast. i took apart the air filter box and teh tub by the sensors, im gunna be spraying that to clean it out, maybe that will do it.

Oh, so the car was running fine immediately after the plugs and wires change then started to run poorly a little while later? About how many miles between the plugs/wires change and the low idle / poor accelleration condition? Does it idle roughly or just lower? I'm maybe starting to think vacuum leak or mis firing plug.

all my spark plugs are firing, it was been about 3,000 miles since the new spark plugs where put in. i seem to have better acceleration after i clean out the hoses in the airline, but still low on the idle. running around 800 rpms at 0 miles an hour when its suppose to be around 1100

where is the vacuum so i can see if i can find the leak, if there is one.
