Hi-Low Rpm's?

[donaldii]

Hey guys,
I tried to search this forum for my question but did not find a specific answer. Any help would be greatly appreciated.
1993 metro lsi convertible 5speed 95000 miles.
As I'm slowing down at a stop sign or red light just as I am almost stopped my rmps go up and down(engine revs) about 3 or 4 times before leveling off. It only does this when the car is warmed up. This is the best way I can describe the problem. Any suggestions?
Thank you

from all the stuff ive read on this site it sounds like the tps is going out on you. i think mine went out on my 94 but mine was worse-would rev to 4500 or so then down to 4or 500 ipulled the part off and no more prob but it did set my check eng light good luck!

Also, check and see if your engine has an ISC solenoid. It's a common problem with the dohc 1.3's, but i'm not sure if the 3cyl was equipped with one.
