Hello, not really around much here but I figured this is the best place i know of to get help. I finally got my 92 RS coupe on the road but i encountered a problem that ive narrowed down to 3 possibilities that i would like you all to see if ya can help me. when my car idles it is usually aroud 1k RPM and dips under a little bit at times and sometimes it will dip that low it stalls out. it also does this when i am backing out at low speed. it also has a hesitant bobble when i get on the gas like it dies and then gets back up and goes. with this all, i could think it is either a bad plug(s) shot wire(s) or maybe a clogged injector(s). i had it running and once it starts going it is fine and no problems at all, sounds really good with the wrong muffler hehe but thats another story. the motor is a 2.2L non ecotec 4 cylinder with 132604 miles on it. the transmission is a 3 speed auto. thanks all for reading this i hope i can figure this out asap with all yall's help!

Sounds like a possibe problem with the TPS "throttle position sensor". Check that but more than likely that sounds like the problem. that might help you out plus tuning it up.
