Ok I bought my first car, a 97 Pontiac Bonneville last year.
Nothing was wrong with it, it drove smooth, no smoke, weird noises, etc... I actually thought that I gat a pretty good deal.
Then (per my mechanic) my oil pressure sensor went out and I needed new motor mounts... Ok, fixed that. It was riding good but soon after started running "Sluggish" all F'd up. (???)
When I start it, it idles really high, then when I put it in drive it goes down a little but idles enough to drive the car around without touching the gas ; ( If I wait awhile and restart the car it will idle normal and drive fine. Lastly, when I'm on the freeway sometimes when I accelerate the car pulls back and feels like it wants to shut off.
I apologize because this could be a stupid question to those that know cars but I kno Nadda. Any suggestions on what it might be cause it wont pass smog????
P.s when I took it to smog everything passed but the computer portion. TB sensor something???

I doubt its a vac issue since there arent many vac lines on that car. The Throttle position sensor sounds accurate. They can cause the car to run irregular and rough when they go bad. I just replaced one like 8 months ago on a 97 suburban.

I would first look at all the vacuum lines -- how well they are connected and if there is any cracks in any of them. Seems like you are sucking air. You could spray brake cleaner on the hoses as you flex them with the other hand while the car is idling in park and see if the engine idle speed changes(higher or stalls) That is the problem hose.

Do you mean the throttle position sensor. it sends a code and if it wont pass then its needs to be changed, this would also have some affect on the runability problem
